idea of "hybrid rigor" has been dis-proven especially when looking at
multi-generational lines. In the first generation it is as likely to
have a negative affect as a positive one, and after several
generations, the worst attributes of both lines usually come out. There
is also little predictability in the quality of offspring, some will be
bad, some terrible, while those who stick to their own breed result in
predictable offspring with the qualities of their parents. There
was a recent study conducted in Iceland, trying to show how their lack
of genetic diversity has harmed them. It turned out, to the researchers
shock, that 3rd and 4th cousins produced the most viable offspring.
They actually proved that breeding with very similar partners was
beneficial, when they set out to prove the opposite. Livestock
breeders have known these things for thousands of years. It is amazing
that most people today can't fathom them. From one breed of wild dog
both chihuahuas and the German Shepard were bred in a very short
period; just image where human evolution could go if we guided it as we
have our animals, or at least protected it from degenerate blood
entering our gene pool.
