Which of the following clades is most likely to survive a series of catastrophic events overtime?

a clade with a few closely related and similar species.
a clade with a few distantly related and diverse species.
a clade with many closely related and similar species.
a clade with many distantly related and diverse species.

2. in the past, mass extinctions encouraged the rapid evolution of surviving species

by changing developmental genes.
by making new habitats available to them.
because they killed all organisms that had coevolved.
because they spared all organisms that had evolved conversantly.

3. the australian flying phalanger is a marsupial flying squirrel. its appearance, behavior,
environment, and diet closely resemble those of the american flying squirrel, a placental
mammal. this resemblance is most likely due to

adaptive radiation.
convergent evolution.
coevolution.
gradualism.

4. gradualism is a pattern of evolution in which

a single species evolves into several closely related species.
several distantly related species develop similarities.
a species evolves at a slow, steady pace.
a species has periods of little evolution interrupted by periods of rapid evolution.

5. mass extinction would most likely result from which of the following events?

a disease kills off a single species of predator within an ecosystem.
a wildfire burns a national park.
global temperatures drop several degrees after several massive volcanic eruptions.
a massive earthquake strikes north america
