conclude that Earth is warming. - -False! Not enough data to show a trend
-Key Point 3 - -When something varies over space and time, one must

uncontrolled factors.

Variation

-Key Point 5 - -Natural Selection occurs whenever heritable phenotypes
cause some individuals to reproduce more than others.
-True or False #8: Organisms evolve by natural selection. - -False! Not
organism but the population.
-True or False: Unlike Wallace, Darwin did not believe that natural selection
required variation among individuals. - -False
-True or False: Wallace used induction to develop a model of evolution by
natural selection. - -True
-True or False: Unlike Wallace, Darwin's conceived his theory of evolution
without observing species living on islands. - -False
