2. Natural Selection
The title of Darwin's evolutionary biology book in
1859 was:
On the Origin of Species by Means of Natural
Selection, or the Preservation of Favoured Races in
the Struggle for Life
10. Natural Selection
For example:
•There is a population of mice living in a parking lot.
Some are white and some are grey.
•When a predator flies over the parking lot, it will eat
the first mouse it sees.
11. Natural Selection
For example:
•Since the grey mice are more difficult to see on the
concrete, white mice will be eaten more often than
grey mice.
•Nature has selected the grey fur allele for survival in
this case.
•The white fur allele may eventually die out in the
parking lot population.
