(True or False)
False
Any variation that can help an organism survive in its environment is called a(n):
adaptation
Characteristics that have come about as a result of common/similar evolutionary descent are said to be
Homologous
Who is considered to be the father of Evolution?

On which islands did Darwin complete his study on the beak sizes of finches?
Galapagos islands
A structure that seems to serve no purpose in an organism is called:
vestigial structure
The most accurate way of determining the degree of relationship between species is probably to compare their
DNA

Vestigial structures
Darwin explained his theory of evolution in a book called
On the Origin of Species
If pollution is cleaned up, what should happen to the color of peppered moths living in the woods?

Population
This picture is an example of what?
homologous structures
What did Darwin observe about the Galapagos finches?
They had different beak shapes which seemed to be based on the available food found on each island

Change over time
Dog breeds we have today were developed through:
artificial selection
Which of the following is NOT a reason why new species form?
Geographic isolation - Reproductive isolation - Differences in mating seasons - Natural Selection
Natural Selection
During their early stages of development, the embryos of reptiles, birds, and mammals look very similar. This suggests that reptiles, birds, and mammals…
Have a common ancestor
Which statement most accurately defines evolutionary “fitness”
The organism’s adaptability to various habitats
“Survival of the Fittest” refers to Darwin’s theory of
Natural Selection

You Grow hair
What is the ultimate source of genetic variation?
mutation

Stabilizing
Through careful observation, Darwin came to understand that…
Those individuals whose variation gives them an advantage in staying alive long enough to reproduce are more likely to pass their traits on to the next generation
Charles Darwin believed that evolution was due to the inheritance of acquired characteristics
