Stickleback becoming victim of ‘reverse speciation’

CBC News highlighted a UBC researcher’s discovery of reverse speciation on Vancouver Island. According to zoology PhD student Seth Rudman, two species of stickleback fish in Enos Lake started to interbreed and eventually disappeared, forming a new single species after crayfish was introduced in the lake.

Rudman believes this loss of genetic diversity is occurring more frequently and in more places.
