Completely Neutral Evolutionary Changes Helped Shape Our Genome
...f various lengths embedded into chromosomes. While chimps
have a comparable number, mice and rats only have around 600 numts. Since they increase in frequency as species advance, it suggested there was some evolutionary purpose to keeping them around. Strikingly, however, none of these numts contained th...
Ancient Viral Defense may Explain Susceptibility to HIV: Study
...ected man from an ancient retrovirus that infected chimps
and other primates millions of years ago may be one reason why our species is susceptible to HIV, said a study released Thursday. The gene appears to have been instrumental in protecting man against a four-million-year-old virus, called Pan troglody...
