o 2. Lyell and Smith-geologists. Strata moves from primitive to
less primitive
o 3. Malthus-food supplies affect populations
x Historical theory of evolution
o Theory of evolution summarized by 3 terms
Variation (we vary in height)
Inheritance (the height we are was passed from
parents)
Differential reproduction (if environment changed in
favour of short ppl, more short ppl would result)
x The driving mechanism behind these
changes=natural selection

advantage and is selected for
o Must be inherited from one generation to
