What is the difference between micro- and macroevolution?

  1. Microevolution describes the evolution of small organisms, such as insects, while macroevolution describes the evolution of large organisms, like people and elephants.
  2. Microevolution describes the evolution of microscopic entities, such as molecules and proteins, while macroevolution describes the evolution of whole organisms.
  3. Microevolution describes the evolution of populations, while macroevolution describes the emergence of new species over long periods of time.
  4. Microevolution describes the evolution of organisms over their lifetimes, while macroevolution describes the evolution of organisms over multiple generations.

  3. the rate of population growth
  4. how genes affect embryological development
6.

Galápagos medium ground finches are found on Santa Cruz and San Cristóbal islands, which are separated by about 100 km of ocean.

  3. gene flow
  4. mutation
7.

10.

Which situation would most likely lead to allopatric speciation?

  1. A flood causes the formation of a new lake.
  2. A storm causes several large trees to fall down.
  3. A mutation causes a new trait to develop.
  4. An injury causes an organism to seek out a new food source.
11.

What is the main difference between dispersal and vicariance?

  1. One leads to allopatric speciation, whereas the other leads to sympatric speciation.
  2. One involves the movement of the organism, whereas the other involves a change in the environment.
  3. One depends on a genetic mutation occurring, whereas the other does not.
  4. One involves closely related organisms, whereas the other involves only individuals of the same species.
12.

Which variable increases the likelihood of allopatric speciation taking place more quickly?

  1. lower rate of mutation
  2. longer distance between divided groups
  3. increased instances of hybrid formation
