vert to where they had started. 180
Luther Burbank, one of the most eminent authorities in

the field of livestock raising, wrote that "there are limits to
the development possible, and these limits follow a law." 181
The biologist Edward Deevey describes how variation
always takes place within specific genetic bounds:

Remarkable things have been done by cross-breeding... but
wheat is still wheat, and not, for instance, grapefruit. We
can no more grow wings on pigs than hens can make
cylindrical eggs.

A more contemporary example is the average increase in
male height that has occurred the past century. Through
better health care (and perhaps also some sexual selection,
as some women prefer taller men as mates), males have
reached a record adult height during the last century, but
the increase is rapidly disappearing, indicating that we
have reached our limit. 182

In short, variations give rise to certain changes that al-
ways remain within the genetic limits of a species, but nev-
er impart to that species any new genetic information. That
is why no variation represents an example of evolution. No
matter how much you crossbreed different breeds of dogs
or horses, the results will still be dogs or horses. No new

species will ever appear, as the agricultural scientist Dr. Don
