Concept 21.3: Evolution is supported by an
overwhelming amount of scientific evidence
 Note that individuals do not evolve; populations
evolve over time
 New discoveries continue to fill the gaps identified
by Darwin in The Origin of Species
 Natural selection can only increase or decrease
heritable traits that vary in a population
 There are four types of data that document the
pattern of evolution
 Adaptations vary with different environments
 Direct observations
 Homology
 The fossil record
 Biogeography
