DNA Evidence For Evolution: Endogenous Retroviruses

An Endogenous Retrovirus is a scar left by virus infection suffered by an ancestor. We can use Endogenous Retroviruses to build evolutionary trees.


Here we explore the amazing discovery of Endogenous Retroviruses (ERVs) in our own DNA. An Endogenous Retrovirus is a genetic remnant of antient virus infection suffered by an ancestor. It turns out that many of our Endogenous Retroviruses are shared by chimpanzees. This is because we share a common ancestor with them.
