Repeated evolution of complex brains: The same retroviral insertion event happened independently in mammals, fishes and amphibians


And here we go again … (there is definitely something very wrong with the theory of evolution)

From a mainstream journal (ScienceDaily.com):

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 result of ancient viral infection, and comparisons of RetroMyelin in mammals, amphibians, and fish suggest that retroviral infection and genome-invasion events occurred separately in each of these groups.
