Darwin & Natural Selection
OUTLINE
(Chapter 15, Pages 368-382)
1.
SCIENCE STANDARDS

S2C1-02: Describe how diverse people and/or cultures,
past and present, have made important contributions to
scientific innovation.

S4C4-01: Identify the following components of natural
selection, which can lead to speciation: Potential for a
species to increase in number, enetic variability and
inheritance of offspring due to mutation and
recombination of genes, finite supply of resources
required for life, and selection by environment of those
offspring better able to survive and reproduce offspring.
