2) a) the process of developing b) gradual development
3) a) change in genetic composition of a population during successive generations, as a result of natural selection acting on the genetic variation among individuals, and resulting in the development of a new species. b) the historical development of a related group of organisms; phylogeny.
“In biology evolution is the process by which populations of organisms acquire and pass on novel traits from generation to generation, affecting the overall makeup of the population and even leading to the emergence of a new species.” – wikipedia.org
I was intending on writing specific evidence for evolution that I have read, studied, or come across but I don't really have the time plus I found a great piece on the evidence for evolution on wikipedia and I’ll just use that for now to read use this link: http://en.wikipedia.org/wiki/Evidence_of_evolution
