We know what retroviruses were up to 407 million years million years ago

The deep history of retroviruses is still obscure. Retroviruses can leave integrated copies within their hosts’ genomes, providing a fossil record for studying their long-term evolution. Endogenous forms of foamy viruses, complex retroviruses known to infect only mammalian species, appear … Continue reading

Be thankful for retroviruses

Retroviruses have had a tremendous impact on animal genomes. At least eight percent of the human genome is comprised of retroviruses at various stages of “fossilization”. These elements represent retroviruses that have directly infected genomes of germline tissues such that … Continue reading
