Well, it's not really a theory... more of a "given." The genetic code is DNA. There's no question it's still incredibly complex... meaning, there are millions upon millions of different protein combinations making up the charactaristics of the human; i.e. the eye color, hair, melanin, growth pattern, finger prints, everything. Basically the "System 32" of your body (if you know computers ). You can take a teaspoon of your DNA and stretch it to the moon and back 500 times. It's been calculated that one person's DNA, if typed out into letters, would fill books filling up the Grand Canyon... 40 times. That's a lot of info.
Now there's the question, was it more complex than it is today? You gotta think about Adam. We're talkin' pre-programmed from the hand of God: first guy. Dogs probably had a common ancestor: dog. Sure, coyotes, wolfs, and dogs all had a start. Scientists have traced back to the gray wolf as being the source. Adam and Eve probably contained all the different code structures in their gene code to create a diverse population, just as the gray wolf had it in his genes to produce all dogs of today, from great dane to chihuahua.
Scientists refer to the "Y-chromosomal Adam" and "mitochondrial Eve" as the source of all humans. You'll find this theory throughout the internet; wikipedia particularly talks about this subject...
...But personally I think I could've told 'em that just from reading Genesis.
