and answers
T/F: scientists before Charles Darwin provides evidence for Evolution - Correct Answers
-True
T/F: Evolution is always a slow gradual process - Correct Answers -False

5 components of Darwin's theory - Correct Answers -Evolution
Common descent
Gradualism
Population change
Natural selection
Evolutuon - Correct Answers -Change in a population or species over time

ancestor
Refer to the figure showing the phylogenetic tree from Charles Darwin's On the Origin of
Species. Based on the figure, which statement is false? - Correct Answers -Darwin
recognized hybridization as an important means of genetic change
A monophyletic group (also called a clade) is defined as: - Correct Answers -the set of
species derived from one common ancestor
Creationists criticize the idea of natural selection as a circular argument, or tautology,
claiming "The fittest are those that survive, and survival is how fitness is defined." Why
is our definition of natural selection not tautological? - Correct Answers -Natural
selection is measured by contribution to the next generation, not simply survival of an
individual organism
Gradualism - Correct Answers -The theory that evolution occurs slowly but steadily
Population change - Correct Answers -Increase or decrease in the size of a population
