from microphotography to molecular biology, with which to examine the process of development in embryos. These new tools reveal that different descendants of a common ancestor do indeed usually go ...

All life on Earth can be traced back to a Last Universal Common Ancestor, or LUCA. A new study suggests that this organism likely lived on Earth only 400 million years after its formation. Further ...

What we can know about biology before the last universal common ancestor is limited—and we should be circumspect in filling in the gaps. In a world in which magical thinking persists in popular ...

These results provided strong evidence that the last universal common ancestor (LUCA ... stimulated extensive studies into the molecular biology of these microbes, many of which thrive in unusual ...

While the common ancestor of vertebrates with synovial joints is still a mystery, the oldest specimen with evidence of these ...

Feathers are among the most complex cutaneous appendages in the animal kingdom. While their evolutionary origin has been ...

In this evolutionary tree, species A and B share a recent common ancestor. Species A is therefore most similar to species B. Species F and G also share a recent, common ancestor, however this ...
