Watch the video clip on slide 3 and then draw a simple tree illustrating the evolutionary relationships between gorillas chimpanzees. Building phylogenetic trees using DNA comparisons is often more objective and less ambiguous than building phylogenetic trees using anatomical comparison. Watch the video clip on slide 3 and then draw a simple tree illustrating the evolutionary relationships between gorillas chimpanzees humans and orangutans.
Watch the short video on slide 4. Answers should include some reference to the greater the sequence divergence then the less DNA sequence they have in common so the organisms are not as related. Those with low divergence share a lot of DNA in sequence and are more closely related.
