Digital reconstruction of ancient chromosomes reveals surprises about mammalian evolution 2017-06-19T04:00:00Z Some of the archaic species, such as taeniodonts, might have stemmed from Cretaceous eutherian ancestors and thus would be among the most primitive placentals on the trunk of the family tree.
