  • results from inductive reasoning
29
Q

theory

A

a set of statements derived from fact, law, and confirmed hypothesis

30

theory of natural selection (2)

A
  • describes how species originated and changed through time

evolution

A

change in the genetic composition of a population of organisms

32
