the stable environment in which species members live
B
the genetic variation within the species
C
the inability of species members to adapt
D
the reproductive difficulties of species members

Suppose a species of snake is living in a certain area. Some of the snakes in the population are black and some are orange. Over time, the area changes and the orange snakes have a harder time blending in with the environment. This makes it difficult for the orange snakes to catch food.According to Darwin’s theory of evolution, what will most likely happen to this snake population over time?

A
Most orange snakes will survive and reproduce, passing on their traits to their offspring. Few black snakes will remain in the population.
B
Most black snakes will survive and reproduce, passing on their traits to their offspring. The number of orange snakes in the population will not change.
C
The black snakes will survive and reproduce, passing on their traits to their offspring. Few orange snakes will remain in the population.
D
Most orange snakes will survive and reproduce, passing on their traits to their offspring. The number of black snakes in the population will not change.
9

How were Lamarck’s and Darwin’s ideas most similar?

A
Both stated that humans should be studied as individuals.
B
Both stated that natural selection drives evolution.
C
Both stated that evolution occurs in an individual’s lifetime.
D
Both stated that traits were passed on to offspring.
10

Which list includes the main components of Darwin’s theory of evolution?

A
Random mutations drive evolution, the evolution of a population happens slowly, organisms have common ancestors, and organisms do not change.
B
Natural selection drives evolution, the evolution of a population happens slowly, organisms have common ancestors, and organisms change over time.
C
Natural selection drives evolution, the evolution of a population happens rapidly, organisms have common ancestors, and organisms change over time.
D
Random mutations drive evolution, the evolution of a population happens rapidly, organisms have common ancestors, and organisms do not change.
