New retroviruses found in polar bear 'Knut' and panda 'Bao Bao'

[unable to retrieve full-text content]Endogenous retroviruses (ERVs) are viruses that at some point in the past inserted themselves into the nuclear genome of a host?s germ cell. Once integrated in a germ cell the virus would be passed on from one generation to the next and the endogenous retroviral genome would therefore be inherited to new species that evolve from the original host.
