Which of the following is TRUE of evolutionary processes?

Ten thousand years ago, most members of Species A were killed by a series of volcanic eruptions. However, some members escaped; all modern members of Species A are descended from those 100 individuals. This is an example of:

Why do most scientists think that we are in the midst of a sixth mass extinction?

Which of the following is an example of coevolution?

In a population of butterflies, there used to be a wide range of sizes: small, medium, and large. But a non-native bird was introduced to the butterfly’s habitat. It loves to eat butterflies, but it can only eat the medium-sized ones. Eventually, medium-sized butterflies became rare. This is an example of:

If sea levels rose 1 metre overnight, what would happen to terrestrial organisms living on the coast?

Identify and explain the human causes of species endangerment and extinction. Propose some actions that could help address each of these issues.

What kinds of predictions can you make about the effects of the current mass extinction on
communities?
ecosystems?
humans?

Based on what you’ve read in the chapter, what can you deduce about the relationship between extinction and islands?

Describe the process of natural selection, using bacterial antibiotic resistance as an example. Apply the requirements for natural selection to the development of antibiotic resistance in your answer. Include examples of human behaviour that have contributed to antibiotic resistance.

Describe the forces that influence evolution. Why do evolutionary rates differ? Why can’t all species adjust to changes in their environment and avoid extinction?
