I always wonder how creationists are so comfortable picking a fight with only specific branches of science--the ones they're threatened by. No one disputes the fundamental laws of thermodynamics. No one questions the aerodynamic principles that allows planes to fly. Because if one did, even creationists would think them touched in the head.
I bet that despite all the arguing and disbelief if a geneticist told a creationist that their kids could suffer from Friedreich’s ataxia, they'd think twice about having kids.
Anyway, I just read an article from 2005 that shows how the Chinese have already done--to a small extent anyway--exactly what this thread hypothesizes about:

Not to go off topic here, but how do creationists deal with the fact that human embryos exhibit certain stages of evolution during prenatal development? We call this ontogeny recapitulating hylogeny... where the development of the individual goes through some of the characteristics of the animals lower in the evolutionary development.
In the example of humans, the common ancestor of humans and monkeys had a tail, and human embryos also have a tail at one point; it later recedes to form the coccyx.
Another example can be found in whales. Whales, which have evolved from land mammals, don't have legs, but tiny remnant leg bones lie buried deep in their bodies. During embryonal development, leg extremities first occur, then recede. Similarly, whale embryos have hair at one stage (like all mammalian embryos), but lose most of it later.
Not only is ontogeny recapitulating hylogeny observed in humans, but it is also directly paralleled in other species. What more, this process can be clearly identified in images taken of early stage embryos, providing direct evidence--the lack of which creationists lament endlessly--and leaving very little ambiguity to interpretation.
What say you?

Generally hybridization of two species is prevented in nature by the characteristics of the gametes such as chromosomal count and genetic instruction sets.
Simply put, DNA is quite literally like a blueprint for a house. For example, it may very simply state, "put bathroom in north-west corner of first floor." The problem is, in incompatible gametes in the counterpart may say, "Put walk-in closet in north-west corner of first floor." As you can imagine a nice little fist fight breaks out in the cellular structure and the zygote self destructs.
This is not to say that interspecies speciation does not occur. According to the following article, about 10% of animal speciation occurs this way:
