Jawed vertebrates, or gnathostomes, underwent a transformative diversification marked by paired jaws, mineralised skeletons and advanced sensory systems. Phylogenetic research integrates fossil ...

Researchers report in the journal Cell that ancient viruses may be to thank for myelin—and, by extension, our large, complex brains. The team found that a retrovirus-derived genetic element or ...

Add Yahoo as a preferred source to see more of our stories on Google. After an ancient extinction killed about 85% of marine species, survivors in isolated refuges helped jawed vertebrates diversify ...

Clarifying how genome duplication and triplication events shaped early vertebrate genomes has presented a challenge in evolutionary biology. The genome of the jawless hagfish provides a missing piece ...

Most of what scientists know about face development comes from studies in bony vertebrates such as mice, chickens, and zebrafish. However, their evolutionary counterparts, cartilaginous fishes, have ...

The sympathetic nervous system was thought to have evolved with jawed vertebrates. But lampreys—jawless, parasitic fish that suck out the blood of their hosts—have a simple one, per recent research.

WASHINGTON (Reuters) - Let's face it. It's easy to take for granted that mammals, birds, reptiles, amphibians and fish - vertebrates just like people - have a face. But it has not always been the case ...

Researchers report that ancient viruses may be to thank for myelin -- and, by extension, our large, complex brains. The team found that a retrovirus-derived genetic element or 'retrotransposon' is ...
