becomes two separate islands when the sea level
rises. What would you expect to happen after a
very long period of time?
A. Competition will increase.
B. Speciation will occur.
C. Interbreeding will continue.

The best measure of evolutionary relationship
between two species can be estimated from
their….
A. length of time on Earth.
B. amount of cooperation.
C. genetic similarities.
D. behavioral similarities.
Complex, multicellular organisms were able to
evolve primarily because…..

According to natural selection, which is the best
explanation of the evolution of the giraffe’s neck?
A. Giraffes evolved long necks so they could eat
the leaves of tall trees.
B. The necks of giraffes gradually got longer as
they reached for the leaves of tall trees.
C. Giraffes were designed to have long necks so
they could reach the leaves of tall trees.
D. Giraffes evolved long necks because those
with longer necks were more likely to pass the
gene to offspring.
How did the identification of genes help explain the
theory of evolution by natural selection?
A. Genes are segments of DNA on chromosomes.
B. Organisms that are “best fit” are more likely to
survive.
C. Species change over time in response to their
environment.
D. Inherited traits are passed to offspring through
genes.

describe one piece of biological
evidence that refutes his theory.
