| 单词 | lobe-finned fish |
| 例句 | Fish with fleshy fins supported at their base by a single bone, known as lobe-finned fish, moved into shallow water about 375 million years ago. Fish had the genes to adapt to life on land—while they were still swimming the seas 2021-02-10T05:00:00Z The features visible on the new snout suggested that Elpistostege was not an amphibian but a highly advanced lobe-finned fish. How a 380-Million-Year-Old Fish Gave Us Fingers 2020-06-17T04:00:00Z Our ancestors then were among lobe-finned fish, with chunky bones held inside fleshy fins. When Fingers Changed Fins 2019-06-01T04:00:00Z Because coelacanths are one of the only lineages of lobe-finned fish alive today, their genome offers a chance to explore this question. 'Living Fossil' Gets Its Genome Sequenced 2013-04-17T18:00:00Z The coelacanth genome is therefore more likely to shed light on the central evolutionary question of what genetic alterations were needed to change a lobe-finned fish into the first land-dwelling tetrapod. Fish’s DNA May Explain How Fins Turned Into Feet 2013-04-17T21:18:01Z Only two groups of the lobe-finned fish are alive today: lungfish and coelacanths. Fish had the genes to adapt to life on land—while they were still swimming the seas 2021-02-10T05:00:00Z It suggests that, contrary to Johanson's argument, the radials of lungfish and other lobe-finned fish are not all equivalent to digits. How a 380-Million-Year-Old Fish Gave Us Fingers 2020-06-17T04:00:00Z Such a bottleneck occurred around the origin of lobe-finned fish. When Fingers Changed Fins 2019-06-01T04:00:00Z In this case, the autopod developmental regulation was derived from an ancestral lobe-finned fish regulatory element. The African coelacanth genome provides insights into tetrapod evolution 2013-04-17T17:21:37.460Z Roughly 400 million years ago, an ancient lobe-finned fish left its watery habitat to become the first four-limbed terrestrial creature. Observatory: African Lungfish Study Indicates That Walking Evolved in the Water 2011-12-19T21:07:24Z About 400 million years ago, they diverged from the line of lobe-finned fish that gave rise to tetrapods 30 million years later. Fish had the genes to adapt to life on land—while they were still swimming the seas 2021-02-10T05:00:00Z If, as his article suggests, claspers are the progenitors of tetrapod limbs, then where do nearly amphibious lobe-finned fish such as Tiktaalik, of the same age as his placoderms, fit in this phylogeny? Readers Respond to "Flu Factories" and Other Articles 2011-04-22T12:45:02.053Z Then surfactant genes, new nervous system genes, and other innovations enabled lobe-finned fish to leave the water temporarily. Fish had the genes to adapt to life on land—while they were still swimming the seas 2021-02-10T05:00:00Z |
