Ancient retroviruses played a key role in the evolution of vertebrate brains
Researchers report February 15 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 “retrotransposon” is essential for myelin production in mammals, amphibians, and fish. The gene sequence, which they dubbed “RetroMyelin,” is likely a … Read more
