A simple "Evolution 101" video that deals with both hybridization and genetic drift. Nice!
Genetic drift is why breeding dogs in a closed registry is always a bad idea, as there is no such thing as a gene pool that will never have health problems.
Mother Nature prefers a wobble.
Hat tip to Patti S. for bird-dogging me to this one.
