Humans possess which of the following traits? Select True or False for each trait.T/F triploblastyT/F parthenogenesisT/F viviparityT/F metamorphosis

What aspect of DNA structure makes it possible for the proteins of nucleotide excision repair to recognize many different types of DNA damage? (a) the polarity of each DNA strand

Studies of DNA support which of the following?a. Members of the group called australopiths were the first to migrate from Africa.b. Homo sapiens originated in Africa.c. Sahelanthropus was the earliest hominin.d. Chimpanzees are more similar to gorillas and orangutans than to humans.

Draw a phylogeny of major populations of modern humans that would reject the out-of-Africa hypothesis.

The earliest members of the genus Homoa. had a larger brain compared to other hominins.b. probably hunted dinosaurs.c. lived about 4 million years ago.d. were the first hominins to be bipedal.

Genetic diversity in living human populations is highest in Africa and decreases as a function of distance traveled by the human migration that left Africa many millennia ago. Draw a graph to show this trend. (Hint: What is the independent variable? What is the dependent variable? What kind of graph is appropriate for this kind of data? Add a label where you would expect to find a data point for the Yanomamö tribe of the Amazon rain forest in South America. Why is it important to use indigenous people for this study?

One of the misconceptions about human evolution is expressed in the question 'If chimpanzees were our ancestors, then why do chimpanzees still exist?' Use Figure 19.10A to explain the answer.

What adaptations inherited from our primate ancestors enable humans to make and use tools?

Summarize the hypotheses that explain variation in human skin color as adaptations to variation in UV radiation.
