1. The species of finches Charles Darwin
found on the Galapagos Islands displayed
what kind of structural adaptation?

2. Why might Darwin have hesitated to
publish his concepts of evolution by
natural selection?
He felt like his findings could be controversial to many people.

1. Lamarck’s theory was false, but why was it
significant to science and the study of
evolution?

time by natural selection was proposed
by…

1. Why are bird wings and reptile forelegs
Homologous structures
evidence of evolution? indicate
a common ancestor.
2. Similar features or structures molded by
natural selection in different species are
what kind of structures? Analogous structures
3. An adaptation is an inherited characteristic
that can be… Physical or behavioral
Please come in and sit in your seat! Once in
your seat, please answer the warm-up
questions!
1. Natural selection is the only mechanism of
evolution that will lead to… Adaptation
2. A snake pelvis is an example of a Vestigial .
structure.

1. What is camouflage and how is it used by
organisms? Allows organisms to become almost invisible to
predators. Helps the organism survive by blending in
with the environment.
2.
What type of selection favors average
phenotypes? Stabilizing
selection
3.
Human DNA is more similar to chimp DNA
than mouse DNA. What kind of evidence of
evolution would this be? Biochemical
Please come in and sit in your seat! Once in
your seat, please answer the warm-up
questions!
1. True or False: Species that have similar
physical characteristics support the
hypotheses that these species originated
from a common ancestor. True
2. Information on genetics and Biochemistry .now
provide compelling evidence of evolution
that was not available to Darwin.
Please come in and sit in your seat! Once in your
seat, please answer the warm-up questions!
1. What was the main evidence of evolution
in Darwin’s time? Fossils
2. What is required from natural selection?
There must be variation among the members of a population.
3. A farmer selecting what animal he wants to
breed would be considered what type of
selection? Artificial selection

1.
If a structure, such as a bird’s and bee’s wings,
have the same function but different structure,
what kind of structure is this? Analogous
2.
True of False: Dark moths surviving on a dark
background and able to reproduce is an
example of strong fitness. True
3.
Members of a species move to a different place
and cannot mate anymore with the original
population, what is this called? Reproductive
isolation
