Textbook Question
Chapter 23, Problem 1TC
Bipedalism has many selective advantages, including the increased ability to spot predators and prey. However, bipedalism has one particular disadvantage—upright posture leads to a smaller pelvic opening, which makes giving birth to an offspring with a large head very difficult. This situation results in a higher percentage of deaths (of both mother and child) during birth in humans compared to other primates. How can you explain the selection tor a trait, such as bipedalism, that has both positive and negative consequences for fitness?

While observing primates at the zoo, you notice that the particular monkey you are watching uses its hands, feet, and tail to grasp branches while moving throughout the trees in its enclosure. This is most likely a(n)
A. New World monkey, because many of these species have a tail with grasping abilities similar to those observed in nonhuman primates hands and feet
B. Old World monkey, because many of these species have a tail with grasping abilities similar to those observed in nonhuman primate hands and feet
C. New World monkey, because these are the only monkeys that live in trees
D. Lesser ape, because many of these species have a tail with grasping abilities similar to those observed in nonhuman primate hands and feet
Scientists speculate or hypothesize that primates evolved to have such traits as nails, grasping hands and feet, forward-facing eyes and depth perception because of their arboreal environs as well as the need to either hunt or to find flowery plants.
is this true or false?
Many lines of evidence, including biochemical evidence, show that living birds are direct descendants of dinosaurs. A number of dinosaur lineages had feathered dinosaurs, not just the lineage that includes living birds. Do you think that is it justified to believe that all feathered dinosaurs had behaviors known from living birds? Such behaviors of birds include colonial nesting, sexual displays by males using feathers, males moving to display their ornamental feathers to female mates. Give a brief reason for your answer.
