UTSG BIO120H1 FINAL EXAM STUDY GUIDELecture 1 Saturday, October 3, 2015 3:20 PM Key Things To Know  Dobzhansky Dobzhansky began analyzing the genes of wild fruit flies, traveling from Canada to Mexico to catch members of the species Drosophila pseudoobscura. He found that different populations of D. pseudoobscura did not have identical sets of genes. Each population of fruit flies he studied bore distinctive markers in its chromosomes that distinguished it from other populations. D...

This is based on the NOVA PBS Documentary, "Evolution - What Darwin Never Knew". This is a summary that provides the important details as clear and simple as possible for a better understanding, as well as some examples mentioned in the video about species evolving. The main details about this documentary is that it covers mutations that prevented genes from turning on, some genes responsible for beak type on each island, and the importance of the timing of the genes working.
