Who concluded that biological evolution occurs as a result of natural selection?
Erwin Chargaff
Charles Darwin
Rosalind Franklin
Robert Hooke
Which of the following is a condition that must be met in order for natural selection to occur?
Individuals must have the same characteristics.
Individuals must produce only the amount of offspring that can survive.
Individuals must be from the same species.
Offspring must inherit some characteristics from their parents.
What are two examples of Genetic Drift?
Bottleneck
Genetic Variation
Founder Effect
Natural Selection
What is a Bottleneck?
Population crashes and greatly reduces number and diversity of population.
Small group leaves to start a new group, which reduces diversity.
Organisms of the same species are able to move back and forth between areas to increase population diversity.
Any genetic change inherited over several generations.
What is the Founder Effect?
Population crashes and greatly reduces number and diversity of population.
Small group leaves to start a new group, which reduces diversity.
Any genetic change inherited over several generations.
Organisms of the same species are able to move back and forth between areas to increase population diversity.
What is Gene Flow?
Small group leaves to start a new group, which reduces diversity.
Organisms of the same species are able to move back and forth between areas to increase population diversity.
Any genetic change inherited over several generations.
Population crashes and greatly reduces number and diversity of population.
What type of evidence for evolution provides the most detailed information for scientists?

Biochemical Evidence
What is Fossil Evidence?
Links present day organisms to the common ancestors.
Compares difference in either DNA or Proteins
Compares Embryos of different species.
