Our human genome is full of viruses similar to HIV-1. These have played an important role in human evolution and still play an important role in human embryology and day-to-day chemistry. Just how important are they to our evolution past and future?
The symbiotic pattern of evolution is everywhere and allows us a very different and fascinating window into the way symbiotic viruses work, since all viruses are symbiotic, including those involved in our human reproduction.
