Lecture 19 molecular homology promoters, moving things around, playing with organization because we are constrained by what came before us, by the branch of the. A lot of evolutionary change is caused by tinkering changing locations of. Current phenotypes are constrained by the past humans are the way we are phylogenetic tree that evolved before us we didn"t just come out of nothing. However, there are other evolutionary processes that are random ie, Similarity can reflect common ancestry but also common solutions suited to the environment, it is not a random process at all. Organism acquires a certain combination of alleles which makes it better. Things look similar because they share a common ancestor from the past, genetic drift homology that is why they are so similar. Human eye and gorilla eye both look very similar, also because they share a common ancestor. Evolution involves many kinds of genetic change. Darwin"s finches have different beaks because they eat different foods-
