[quote1326929127=KeyserSoze] I was watching the series Ancient Aliens and they were saying that homo sapiens were created from alien DNA and prehistoric humans with all kinds of evidence from all over the world. It got me thinking that maybe man's best friend was created from alien DNA and the wolf. [/quote1326929127] Alright, I will try to tackle this. If we assumed that this premise were indeed a plausible possibility, then we could never really know for sure unless we had an actual peek at concrete alien DNA. Without any evidence of its actual existence or information, we cannot claim that dogs contain any. Moreover, wolves and dogs breed freely and create fertile offspring, so for all genetic purposes these two genomes are 100% compatible. Personally, I am subscribed to Occam's razor, so generally I tend towards the most probable explanations. Alien DNA ain't one of them. [quote1326929127=KeyserSoze] I just don't see how the wolf has any DNA that some dogs do now. [/quote1326929127] Well, actually the wolf has ALL the DNA that various dogs do. Dogs only exhibit small subsets of aspects of a wolf's inherited repertoire. To illustrate what I mean, one could compare this to a tree and a piece of wooden furniture. One may not be able to see how a tree has any of the stuff that some pieces of wooden furniture do, but as a matter of fact various pieces of wooden furniture all share what a tree has to offer, namely a big chunk of wood. In essence, wooden furniture represents nothing but different shapes of the same thing. Now throw in a bunch of genetic syndromes and you get the whole modern breed variety of the AKC.
