Darwin's main contribution was to come up with the idea of
a mechanism for evolutionary change
The small, functionless hind limb bones of a whale illustrate
vestigial organs
The survivorship of human babies of different birth weight illustrates
stabilizing selection
In the peppered moth story, were any melanic moths born into the population BEFORE the
Industrial Revolution?
yes
The change in the moth population from mostly peppered moths to mostly melanic moths is an

Radiometric dating of rocks relies on knowing
the half-life of elements in the rock
How as geological evidence important in supporting the idea of evolution?
it showed the earth was very old, fossils showed life in the past and showed a progression of
increasing organismal complexity from past to present, slow precesses like erosion could
produce large results (e.g. the Grand canyon) in the same way the slow process of evolution
could produce big results
What was Darwin's term for evolution
descent with moedifcation
Why did melanic moths have higher survivorship than the peppered moths after pollution
occurred?
they were more camouflaged against the blackened tree trunks
What factors are responsible for the variation in a population from one generation to the next?
genetic recombination during gamete formation and the random union of gametes in sexual
reproduction
