Primate evolution

Primates are a relatively new species and first appeared in the fossil record nearly 55 million years ago. They may have originated as far back as the cretaceous period. Their fossils were observed in North America, Asia, and Europe. Long before the first monkeys and their prosimian relatives developed, most animal species thrived and died. The first primates did not exist until about 50-55 million years ago, even though the planet is 4.54 billion years old and the first life goes back at least 3.5 billion years. Dinosaurs had been extinct for 10 to 15 million years when this happened.

. The upper forelimbs of humans and bats have fairly similarskeletal structures, whereas the corresponding bones inwhales have very different shapes and proportions. However,genetic data suggest that all three kinds of organisms divergedfrom a common ancestor at about the same time. Which ofthe following is the most likely explanation for these data?(A) Forelimb evolution was adaptive in people and bats, butnot in whales.(B) Natural selection in an aquatic environment resulted insignificant changes to whale forelimb anatomy.(C) Genes mutate faster in whales than in humans or bats.(D) Whales are not properly classified as mammals.
Recent reconstructions of evolutionary history are often dependenton assigning divergence in terms of changes in amino acid ornucleotide sequences. For example, a comparison of cytochromec shows 10 amino acid differences between humans and dogs,24 differences between humans and moths, and 38 differencesbetween humans and yeast. Such data provide no information asto the absolute times of divergence for humans, dogs, moths, andyeast. How might one calibrate the molecular clock to an absolutetime clock? What problems might one encounter in such acalibration?

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?

Which of the following statements is BEST supported by the phylogenetic tree? A The development of a bony skeleton was a significant evolutionary step for ocean-dwelling animals.

D The evolution of the amniotic egg was specific to ocean-dwelling animals.

Knowledge of the genomes of ancient homininsmight help us better understand not only the evolutionaryhistory of hominins, but also the traits that differ between usand our relatives—the traits that make us human. Our understandingof the functions of different genes is growing rapidly,so detailed comparisons of our genes to those present in, say,Neanderthals and Denisovans are very revealing. What do youthink are the functions most likely to be related to the geneticdifferences between us and our hominin relatives?
House sparrows (Maya) were introduced to North America in 1852. Since that time thesparrows have evolved different characteristics in different locations. Sparrow populations inthe north are larger-bodied than sparrow populations in the south. This divergence inpopulations is probably at least partly a result of natural selection: larger-bodied birds canoften survive lower temperatures than smaller-bodied birds can. Colder weather in the northmay select for larger-bodied birds. What type of evolution based on natural selectionaccounts for this observation? Explain your answer.
When I first studied hominin evolution, they had found "Lucy", an Australopithecus afarensis, and everyone thought her species was an early ancestor of Homo sapien. The picture is much more complicated, with lots of hominins living in close proximity for millions of years...much different than our now singular species. Look at the phylogenetic tree and use it as a guide to briefly describe hominin lines in Africa up to Homo. Do not discuss Homo.Just discuss a sense that you generally can grasp what was going on in Africa with our Genus for 6 or 7 million years!
