Around 25 million years ago, an evolutionary split occurred between our ancestors, the precursors of humans and apes, and ...

Losing their kitten features is part of every cat’s growth journey, but the process rarely follows a predictable path. What starts out small and subtle can turn bold and exaggerated as time passes.

As early vertebrates emerged from the water, their tails may have played a crucial role in helping them move across land, a new study reports. The results, based on animal and robot models, as well as ...

When you think about a whale, you probably picture an enormous sea creature without legs. But what if I told you the first whale had four legs and could walk on land? I talked about whales and other ...

POUGHKEEPSIE, N.Y. -- Robots wag their tail fins and bob along like bathtub toys in a pool at a Vassar College lab. Their actions are dictated by microprocessors housed in round plastic containers, ...

Understanding both the role of selection in driving phenotypic change and its underlying genetic basis remain major challenges in evolutionary biology. Here, we use modern tools to revisit a classic ...

For most vertebrates, losing a limb is permanent, but a lucky few species -- such as salamanders and tadpoles -- have the ability to completely regrow complex body parts. Understanding the molecular ...
