Every living thing today is a descendant of something that crawled out of the primordial ooze. And now using an old fossil of one of the most ancient fish species known, scientists might be able ...

Scientists sequenced the 91 billion base pairs in the South American lungfish’s genome, setting a record and revealing insights into vertebrate evolution ...

To answer these questions, they constructed a phylogenetic tree from 22 jawed vertebrate species and compared their RetroMyelin sequences. The analysis revealed that RetroMyelin sequences were more ...

Next, the researchers wanted to know whether RetroMyelin was incorporated once into the ancestor of all jawed vertebrates or whether there were separate retroviral invasions in the different branches.

Myelin first appeared in the tree of life around the same time as jaws, and its importance in vertebrate evolution has long been recognized, but until now, it was unclear what molecular mechanisms ...

Nevertheless, “this fossil fills a gap in our knowledge of the evolution of the vertebrate head,” said paleobiologist Lauren Sallan, an assistant professor in the macroevolution unit at the ...

Largest ever family tree of humanity reveals our species' history A genealogy of humans constructed from thousands of genomes gives us clues about where our species first evolved and how we spread ...

For years, scientists have been intrigued by the mechanism by which large exons redeem their presence and retention in the course of vertebrate evolution.

A jawless, bloodsucking fish, the lamprey is often considered an ancestral early vertebrate for its rudimentary morphology and its larval life stage.
