Early in pregnancy, something surprising happens. Every human embryo develops a tail. It is not symbolic or imagined. A real ...

Learn more about the gene linked to the evolutionary loss of human tails, and how, in rare cases, some people are still born with them.

They’re not monkeying around with this breakthrough. Researchers from New York University Langone Health may have finally learned how early humans took a major step away from predecessor primates in ...

The human tailbone, also known as the coccyx, is a vestigial feature, meaning it has lost its original function in the body over the course of evolution. The human tailbone is a leftover feature from ...

A genetic change in our ancient ancestors may partly explain why humans don't have tails like monkeys, finds a new study led by researchers at NYU Grossman School of Medicine. Published online ...

Humans do not have tails, but do we have “what it takes” for a tail? Hens don’t have teeth, but they have the genes for it. With atavism, it is as if our genomes serve as archives of our evolutionary ...

The human body is a machine whose many parts – from the microscopic details of our cells to our limbs, eyes, liver and brain – have been assembled in fits and starts over the four billion years of our ...

If we look across the whole of the mammal branch of the tree of life, we find there are many groups of mammals that have ...
