A Racial Study of the Fijians 2012-03-15T02:00:31.197Z The American grey squirrel, for example, passes a deadly virus to native red squirrels, whilst European hares threaten the ecological and genetic integrity of the native Irish hare through competition and interbreeding. Warning over native Irish species 2012-02-21T06:32:42Z The value of the interbreeding shows up in the immune system, Dr. Parham’s analysis suggests. Gains in DNA Are Speeding Research Into Human Origins 2012-01-31T00:23:17Z I have become even more interested in Gambel’s quail after realizing that they could potentially be the gatekeepers for genetic introgression — the swapping of genes between species through interbreeding — among all the Callipepla quail. Scientist at Work Blog: Quail Hybridization in Mexico 2011-12-28T22:50:17Z Somewhere in Southeast Asia is the most likely place they would have had interbreeding with the Denisovans. A Conversation With Chris Stringer: Chris Stringer on the Origins and Rise of Modern Humans 2012-07-16T17:20:00Z At that time the species probably was a continuously interbreeding unit. Speciation of the Wandering Shrew 2011-12-22T03:00:30.143Z There is evidence that a barrier occurred in the Pleistocene in central M�xico sufficient to separate the supposed interbreeding, relatively homogeneous populations of pygmy mice. Speciation and Evolution of the Pygmy Mice, Genus Baiomys 2011-12-15T03:00:11.933Z Dr. Reich and others suggest that the interbreeding that led to this phenomenon probably occurred in the south, rather than in Siberia. Gains in DNA Are Speeding Research Into Human Origins 2012-01-31T00:23:17Z The interbreeding of these different classes of population resulted in creole types, characteristic of each region. The Social Evolution of the Argentine Republic 2011-11-24T03:00:43.903Z The argument went that we remained one species throughout that evolutionary process, because there was interbreeding among the different populations. A Conversation With Chris Stringer: Chris Stringer on the Origins and Rise of Modern Humans 2012-07-16T17:20:00Z The animals of this western segment and the new arrivals from the east were by this time so different from one another that the two kinds lived in the same areas without interbreeding. Speciation of the Wandering Shrew 2011-12-22T03:00:30.143Z And the fish have to be killed to prevent interbreeding with the smaller stock of natural wild salmon. Appetite For Catch And Release Tempered at Delphi Lodge 2011-10-22T16:21:27Z Whence it inevitably follows, as a matter of simple logic, that where divergence has occurred, intercrossing and interbreeding must in some way have been lessened or prevented. Darwin, and After Darwin (Vol 3 of 3) Post-Darwinian Questions: Isolation and Physiological Selection 2011-10-18T02:00:18.363Z The interbreeding with the Indians formed an inferior class of half breed which approached the type of the mother more than that of the father and which was certainly not a robust or handsome race. The Social Evolution of the Argentine Republic 2011-11-24T03:00:43.903Z Do you now accept the new evidence of Neanderthal-Homo sapiens interbreeding, which seems to establish that we are more than 2 percent Neanderthal? A Conversation With Chris Stringer: Chris Stringer on the Origins and Rise of Modern Humans 2012-07-16T17:20:00Z Many contemporary Aboriginal Australians also descend from Europeans because of recent interbreeding between Aboriginals and Australian colonists. Hair Sample Yields First Complete Genome of an Aboriginal Australian 2011-09-22T23:15:05.773Z Experiments in interbreeding of cattle go to prove that in some cases, at least, this may be continued for many generations with no unfavorable results. Insanity Its Causes and Prevention 2011-08-29T02:01:05.400Z Its importance, indeed, can only be denied by denying the swamping effects of intercrossing, and such denial implies the tacit assumption that interbreeding and interblending are held in check by some form of segregation. Darwin, and After Darwin (Vol 3 of 3) Post-Darwinian Questions: Isolation and Physiological Selection 2011-10-18T02:00:18.363Z In this way the creoles, the product of interbreeding, were recast into the dense mass of the Indian population and became more conversant with American traditions than Spanish. The Social Evolution of the Argentine Republic 2011-11-24T03:00:43.903Z Specimens referrable to the Indigo Bunting have been taken as far west as Finney County, but most specimens from that far west show evidence of interbreeding with Lazuli Buntings. The Breeding Birds of Kansas 2011-08-27T02:00:24.797Z By comparing individual DNA letters in multiple modern human genomes with those in the Neanderthal genome, the date of that interbreeding has now been pinned down to 65,000–90,000 years ago. Ancient DNA reveals secrets of human history 2011-08-10T17:20:25.990Z They are interbreeding with the resident worms, and the resistant mutations are becoming rarer. Evolution Right Under Our Noses 2011-07-25T16:35:11Z These two local varieties, being by the terms of his supposition better adapted to the environment than the freely interbreeding forms in other parts of the general area, increase till they supplant these original forms. Darwin, and After Darwin (Vol 3 of 3) Post-Darwinian Questions: Isolation and Physiological Selection 2011-10-18T02:00:18.363Z One possible explanation, Durbin says, is that after the first humans left Africa some 60,000 years ago, successive waves of Africans followed suit, interbreeding with the ancestors of the earlier migrants. First Humans Who Left Africa Continued to Mate with Africans 2011-07-14T00:15:05.750Z The species hybridizes freely with the Baltimore Oriole, and most Bullock Orioles in Kansas show evidence of such interbreeding. The Breeding Birds of Kansas 2011-08-27T02:00:24.797Z Reich's team is now developing tools to find signs of more recent interbreeding that might have occurred after humans arrived in Asia and Europe. Ancient DNA reveals secrets of human history 2011-08-10T17:20:25.990Z At the same time, the two species are interbreeding, producing hybrids. Evolution Right Under Our Noses 2011-07-25T16:35:11Z The finding also shows that interbreeding doesn't necessarily destroy a species. Polar Bears Rooted in Ireland 2011-07-07T17:15:00Z Especially, as Robert Sinnott, the chief executive of Kayne Anderson Capital Advisors, put it, when the markets seem like “a pond with black swans interbreeding and laughing at us.” DealBook: Gloom and Doom, and How to Profit From It 2011-05-12T21:26:51Z The smallness and isolation of their communities must necessitate close interbreeding; and I think it very possible this may cause the physical deterioration of their race.” Explorers and Travellers 2011-05-11T02:00:17.627Z The interbreeding, they postulate, occurred not in Europe 40,000 years ago but in an earlier encounter 100,000 years ago. Neanderthals and Early Humans May Not Have Mingled Much 2011-05-09T20:41:24Z Starting in 2003, biologists began interbreeding Columbia Basin pygmy rabbits with kin from Idaho. Believing in the Pygmy Bunny 2011-04-21T17:19:00Z Given even more time, those smaller populations will stop interbreeding, and become different enough to call separate species. Ecological opportunity: The seed of evolutionary change in your backyard--and in your veins 2011-02-21T14:15:05.737Z This mingling of characteristics of different animals is not to be attributed to interbreeding, but is the converse of the combination of characters found in hybrid animals. Dragons of the Air An Account of Extinct Flying Reptiles 2011-02-20T03:00:13.067Z The width of the genetic divide suggests there is very little or no interbreeding between the groups, the team reports in the 4 February issue of Science. 'Outdoor Mosquito' May Have Unexpected Role in Malaria 2011-02-03T19:01:00Z Dr. Klein said interbreeding between the two species was perfectly possible in principle, “but it’s kind of anti-archaeological because there is no evidence that they overlapped” in the Near East. Neanderthals and Early Humans May Not Have Mingled Much 2011-05-09T20:41:24Z The study follows a paper published earlier this year by Professor Paabo and colleagues that showed there was interbreeding between modern humans and Neanderthals as they emerged from Africa 60,000 years ago. Ancient humans interbred with us 2010-12-22T18:03:12Z The study follows a paper published earlier this year by by Professor Paabo and colleagues that showed there was interbreeding between modern humans and Neanderthals as they emerged from Africa 60,000 years ago. Ancient humans interbred with us 2010-12-22T18:03:12Z Next, the researchers looked for evidence of interbreeding. Siberian Fossils Were Neanderthals? Eastern Cousins, DNA Reveals 2010-12-22T18:01:18Z The first comparisons of small sections of Neanderthal DNA did not indicate any hybridization, and the lack of interbreeding became a widely accepted conclusion. Remarkable Creatures: Hybrids May Thrive Where Parents Fear to Tread 2010-09-16T03:31:00Z "A little interbreeding would have spread those genes far and wide," said British anthropologist Chris Stringer at London's Natural History Museum. Most People Carry Neanderthal Genes 2010-05-07T00:02:00Z Just last year, when biologists first announced they had decoded the Neanderthal genome, they reported no significant evidence of interbreeding. Study Says Neanderthals May Have Mated With Humans 2010-05-06T20:43:00Z The interbreeding occurred after modern humans left Africa but before they diversified, through chance and natural selection, into the ethnic groups that exist today. Neanderthal DNA found in some modern humans, scientists say 2010-05-06T19:48:00Z Dr. Bustamante also thinks that other cases of interbreeding are yet to be discovered. Siberian Fossils Were Neanderthals? Eastern Cousins, DNA Reveals 2010-12-22T18:01:18Z If that is the case, it would have occurred significantly earlier than scientists who support the interbreeding hypothesis would have expected. Scientists Sequence the Neanderthal Genome 2010-05-06T20:05:00Z That suggests that interbreeding occurred in the Middle East, where both modern humans and Neanderthals lived thousands of years ago, he said. You're a Neanderthal: Genes say yes, a little bit 2010-05-06T18:15:00Z But the Leipzig team’s second conclusion, that there was probably interbreeding between Neanderthals and modern humans before Europeans and Asians split, is being greeted with reserve by some archaeologists. Study Says Neanderthals May Have Mated With Humans 2010-05-06T20:43:00Z "Although I have never ruled out the possibility of interbreeding, I have considered this to have been small and insignificant in the bigger picture of evolution." Neanderthal genes 'survive in us' 2010-05-06T18:02:00Z However, the scientists were surprised to find a large population of a hybrid species of orchid growing nearby, created by interbreeding between Ophrys arachnitiformis and Ophrys lupercalis . Light shed on bee-tricking orchid 2010-04-21T09:16:00Z It is not clear whether interbreeding may have happened a few times among small populations or frequently among large populations — the genetic remnants would look the same to scientists' current technology. Scientists Sequence the Neanderthal Genome 2010-05-06T20:05:00Z This has resulted in interbreeding between the wild caribou and their inferior domesticated relatives. The Barren Ground Caribou of Keewatin Richard Klein, a paleontologist at Stanford, said the authors’ scenario of an early interbreeding episode did not seem to have taken full account of the archaeological background. Study Says Neanderthals May Have Mated With Humans 2010-05-06T20:43:00Z The most conservative model proposes that this replacement took place with no interbreeding between modern humans and Neanderthals. Neanderthal genes 'survive in us' 2010-05-06T18:02:00Z On the basis of field and laboratory observations he tentatively concluded that one of the main barriers to interbreeding was the reluctance of the males of carolinensis to clasp the smaller females of olivacea. Field Study of Kansas Ant-Eating Frog They are admirably suited for window and greenhouse culture and are interesting subjects for interbreeding, though no startling results should be expected. The Gladiolus A Practical Treatise on the Culture of the Gladiolus We have also seen that the inhabitants sometimes introduce cattle on their estates to prevent the evil effects of close interbreeding. The Variation of Animals and Plants Under Domestication, Volume II (of 2) If there was any interbreeding, the flow of genes should have been both ways, Dr. Klein said, but Dr. Paabo’s group sees evidence only for gene flow from Neanderthals to modern humans. Study Says Neanderthals May Have Mated With Humans 2010-05-06T20:43:00Z The authors of the paper in Science do not rule out some interbreeding in Europe, but say it was not possible to detect this with present scientific methods. Neanderthal genes 'survive in us' 2010-05-06T18:02:00Z They are quite evidently a distinct race from the Japanese proper, although of course there has been some interbreeding between them. The Empire of the East Neither interbreeding nor interaction has created, in what the French term "nationals," a more than superficial likeness or like-mindedness. Introduction to the Science of Sociology Close interbreeding, on the other hand, induces sterility; and this indicates something quite distinct from the augmentation of morbid tendencies common to both parents. The Variation of Animals and Plants Under Domestication, Volume II (of 2) The Leipzig group’s interbreeding theory would undercut the present belief that all human populations today draw from the same gene pool that existed a mere 50,000 years ago. Study Says Neanderthals May Have Mated With Humans 2010-05-06T20:43:00Z Yet interbreeding has doubtless been an important element in the elaboration of the stupendous caste organization. India, Its Life and Thought An ecological analysis of the interbreeding of Crested Titmice in Texas. Birds from Coahuila, Mexico Amalgamation is a biological process, the fusion of races by interbreeding and intermarriage. Introduction to the Science of Sociology Although nothing is directly known on the evil effects of long-continued close interbreeding with plants, the converse proposition that great good is derived from crossing is well established. The Variation of Animals and Plants Under Domestication, Volume II (of 2) We believe that under eastern conditions the only opportunities for outdoor breeding work will lie along the line of interbreeding with peaches and almonds. Northern Nut Growers Association Report of the Proceedings at the 13th Annual Meeting Rochester, N.Y. September, 7, 8 and 9, 1922 From the most northern colonies as far south as Florida there was much contact resulting in the interbreeding of Indians and Negroes. The Journal of Negro History, Volume 5, 1920 And thus, the strange fact of the increase of fertility in the successive generations of artificially fertilised hybrids may, I believe, be accounted for by close interbreeding having been avoided. On the Origin of Species by Means of Natural Selection or the Preservation of Favoured Races in the Struggle for Life. (2nd edition) The splendid work of our President in the interbreeding of northern types of nuts gives us strong hope to expect results of this nature. Northern Nut Growers Association Report of the Proceedings at the Second Annual Meeting Ithaca, New York, December 14 and 15, 1911 In relation to the subject of domestication, the whole question is of some importance, as too close interbreeding interferes with the improvement of old races, and especially with the formation of new ones. The Variation of Animals and Plants Under Domestication, Volume II (of 2) A biological objection has also been alleged, in the possibility of interbreeding between the yellow and white races. Applied Eugenics Forsyth doubts their interbreeding with the domestic race, but I see no reason for this. Natural History of the Mammalia of India and Ceylon If we could only mix our blood with theirs, through interbreeding, maybe we could end the tragedy of sure death in adolescence. The Mantooth This constant interbreeding of individuals will tend to prevent the formation of many modifications in the machine which become started by variations. The Story of the Living Machine A Review of the Conclusions of Modern Biology in Regard to the Mechanism Which Controls the Phenomena of Living Activity With Pigs there is more unanimity amongst breeders on the evil effects of close interbreeding than, perhaps, with any other large animal. The Variation of Animals and Plants Under Domestication, Volume II (of 2) All experimental evidence obtained by interbreeding of animals shows that close interbreeding is not productive of variation, but that variations existing in the breed become accentuated. Disease and Its Causes In other respects there is little difference between goats and sheep, and by interbreeding they produce a fertile offspring. Natural History of the Mammalia of India and Ceylon We have seen how both these classes of organisms may be rendered infertile, by a change of conditions which does not affect their general health, by captivity, or by too close interbreeding. Darwinism (1889) There is no variation of the social monotony, and the result is socially the same as close consanguineal interbreeding. Consanguineous Marriages in the American Population Turning now to Birds: in the case of the Fowl a whole array of authorities could be given against too close interbreeding. The Variation of Animals and Plants Under Domestication, Volume II (of 2) The big red wolf of the South American plains is not closely related to the northern wolves; and it was to me unexpected to find it interbreeding with ordinary domestic dogs. Through the Brazilian Wilderness It is not as I said before, that we should go upon peculiarities of marking and colour, although these are sufficiently obvious, but on their osteology and also the question of interbreeding and production. Natural History of the Mammalia of India and Ceylon It appears probable, then, that it is not interbreeding in itself that is hurtful, but interbreeding without rigid selection or some change of conditions. Darwinism (1889) Every age is an age of transition, of minglings, of the breaking up of old, narrow cultures, and the breaking down of barriers, of spiritual and often of actual interbreeding. An Englishman Looks at the World With Cattle there can be no doubt that extremely close interbreeding may be long carried on, advantageously with respect to external characters and with no manifestly apparent evil as far as constitution is concerned. The Variation of Animals and Plants Under Domestication, Volume II (of 2) Also experiments with the interbreeding of animals have shown similar results. The Evolution of Man Scientifically Disproved In 50 Arguments Domestic dogs can become, and again and again do become, wild, even consorting with wolves, interbreeding with them, assuming their gregarious habits, and changing the characteristic bark into a dismal wolf-like howl. Dogs and All about Them Just as we have seen that intercrossing is not necessarily good, we shall be forced to admit that close interbreeding is not necessarily bad. Darwinism (1889) The teeth of these two kinds of bears show a marked and uniform difference, proving conclusively that there is no interbreeding between the species. American Big Game in Its Haunts He produced the famous Sebright Bantams by complicated crosses, and by breeding in-and-in; and since his time there has been much close interbreeding with these Bantams; and they are now notoriously bad breeders. The Variation of Animals and Plants Under Domestication, Volume II (of 2) If evolution be true, we would expect a frequent interbreeding and interchanging of species. The Evolution of Man Scientifically Disproved In 50 Arguments Under such circumstances, the variety can only have been preserved through not interbreeding with the common form, either from a dislike to such unions, or by some amount of sterility when they are formed. The Naturalist in Nicaragua In the second generation these two stocks might be themselves crossed to prevent the evil effects of too close interbreeding. Darwinism (1889) No case has as yet been brought forward in which varieties have been produced which were not capable of interbreeding. Story of Creation as Told By Theology and By Science Moreover, the fertilisation of a flower by its own pollen corresponds to a closer form of interbreeding than is possible with ordinary bi-sexual animals; so that an earlier result might have been expected. Effects of Cross and Self Fertilisation in the Vegetable Kingdom It certainly would be impossible for one single pair to have become the ancestors of the human race, without mixing and interbreeding with their kindred primates. The Evolution of Man Scientifically Disproved In 50 Arguments We have also seen that the inhabitants sometimes introduce fresh cattle on their estates to prevent the evil effects of close interbreeding. The Variation of Animals and Plants under Domestication — Volume 2 To carry out these experiments with any satisfactory result, it will be necessary to avoid the evil effects of confinement and of too close interbreeding. Darwinism (1889) Discussion on the effects of close interbreeding in the case of man. The Variation of Animals and Plants under Domestication — Volume 1 As some kinds of plants suffer much more from self-fertilisation than do others, so it probably is with animals from too close interbreeding. Effects of Cross and Self Fertilisation in the Vegetable Kingdom There the primitive germ is preserved intact and transmitted from one generation to another, renewed and invigorated by interbreeding. The Modern Regime, Volume 1 In relation to the subject of domestication, the whole question is of some importance, as too close interbreeding interferes with the improvement of old races. The Variation of Animals and Plants under Domestication — Volume 2 The facts on self-impotent plants seem to me curious, and I have worked out to my own satisfaction the good from crossing and evil from interbreeding. Life and Letters of Charles Darwin — Volume 2 But I believe that their fertility has been diminished in nearly all these cases by an independent cause, namely, by too close interbreeding. The Origin of Species by means of Natural Selection, 6th Edition The effects of close interbreeding on animals, judging again from plants, would be deterioration in general vigour, including fertility, with no necessary loss of excellence of form; and this seems to be the usual result. Effects of Cross and Self Fertilisation in the Vegetable Kingdom Sterility various in degree, not universal, affected by close interbreeding, removed by domestication. On the Origin of Species By Means of Natural Selection, or, the Preservation of Favoured Races in the Struggle for Life Close interbreeding, on the other hand, often induces sterility; and this indicates something quite distinct from the augmentation of morbid tendencies common to both parents. The Variation of Animals and Plants under Domestication — Volume 2 The facts now to be given differ from the foregoing, as self-sterility is not here the result of long-continued close interbreeding. The Variation of Animals and Plants under Domestication — Volume 2 I should add that the good effects of intercrossing, and the ill effects of close interbreeding, no doubt come into play in many of these cases; but I will not here enlarge on this subject. The Origin of Species by means of Natural Selection, 6th Edition Unfortunately we do not know whether an animal like the cat, which is not gregarious, would suffer from close interbreeding in a greater degree than our other domesticated animals. The Variation of Animals and Plants under Domestication — Volume 2 He produced the famous Sebright Bantams by complicated crosses, and by breeding in-and-in; and since his time there has been much close interbreeding with these animals; and they are now notoriously bad breeders. The Variation of Animals and Plants under Domestication — Volume 2 With greyhounds also there has been much close interbreeding, but the best breeders agree that it may be carried too far. The Variation of Animals and Plants under Domestication — Volume 2 But the pig is not, as far as I can discover, strictly gregarious, and we have seen that it appears eminently liable to the evil effects of close interbreeding. The Variation of Animals and Plants under Domestication — Volume 2 The effects of close interbreeding in the case of man is a difficult subject, on which I will say but little. The Variation of Animals and Plants under Domestication — Volume 2 They often desert their young, so that it is necessary to have nurse-rabbits, but I do not pretend to attribute all these evil results to close interbreeding.
