How did all the different body types in the Cambrian arise so quickly? O Hox genes had evolved that determine and allow for the diversification of body plans. Because Hox genes hadn't evolved yet, there was a lot of flexibility in how body plans could develop. O There was a genome duplication event that led to the diversification of body plans. Enhancer driven gene expression had just evolved, which made it easier to vary body plans. Toing wheroptiones 29
Scientists know that the last common ancestor between chimpanzees and humans lived 5-7 million years ago because: O It lived shortly after the disappearance of the dinosaurs at 10 million years ago. O The carliest hominins were found in woodlands The time the last common ancestor existed can be calculated by comparing chimpanzee and human DNA and using a "molecular clock" O Chimpanze fossils first appear in the fossil record 10 million years ago

Imagine that you have the DNA sequences fromthe intron of a gene in three species called A, B,and C. Species A and B are most closely related,while C is more distantly related. The sequencesof A and B differ by 18 base pairs, A and C differby 26 base pairs, and B and C differ by 28 basepairs. Fossils show that species A and B divergedabout 1.2 Mya, but there is no fossil evidence asto when the most recent common ancestor ofall three species lived. Use the genetic data toestimate that date. What assumptions are youmaking to get this estimate?
The diversity of modern vertebrates was shaped in partby mass extinctions. The most severe extinction eventwe know of occured at the border between the Permianand Triassic periods about 250 million years ago. Anestimated 96 percent of the marine species and 70 percentof land species disappeared in what is sometimes called“The Great Dying.” The cause of this mass extinctionremains under investigation. Suggested causes includean asteroid impact, extreme volcanic activity, or a sudden release of carbon dioxide from deposits on the sea floor. Which groups of vertebrates were present when this mass extinction event occurred? Which evolvedafterward?
