Viviparity, the live-bearing mode of reproduction, has evolved independently in several vertebrate lineages, including squamate reptiles and seahorses. In reptiles, evolutionary transitions from ...

A feeding method of the extinct jawless heterostracans, among the oldest of vertebrates, has been examined and dismissed by scientists, using fresh techniques. A feeding method of the extinct jawless ...

What really did come first--the chicken or the egg? Birds' reproductive biology is dramatically different from that of any other living vertebrates, and ornithologists and paleontologists have long ...

The study revealed unexpected and sex-specific effects of germline regulation on longevity and somatic repair in vertebrates. Contrary to classical evolutionary theories, it turns out that changing ...
