Genetic Resarch

Am investigating Shawn Carroll's The Making of the Fittest.. and find genetic research to be utterly a fascinating endeavor. He's from the University of Wisconsin. Forensic dna records can now explain why genetic development of certain species happened that way. The selection process is predictable and not random whereas the mutated genes and non functional genes are random. He also discusses "trichromatic vision", full color spectrum vision, which we as humans have and not all mammals have this full spectrum.Some birds have ultraviolet perception we don't have.
