What is a evolution
Random change to genetic material
Mutation
Genetic Drift tends to happen in populations that are
This is the study of how creatures develop before being born or hatching from an egg.
Embryology
Name the theory that explains how organisms change because of adaptations that help them survive
What is natural selection
Random movement of individuals between populations which increases genetic diversity is known as (2 words)
Gene Flow

Comparative Biochemistry suggests that molecules in species with a a recent common ancestor also share....
amino acid/DNA sequences
Evolution can be defined as any change in the (physical or behavioural characteristics) with in a population over time
What are heritable traits
This occurs when the probability that two individuals in a population will mate is not the same for all possible pairs of individuals. (2 words(=)
Non-Random Mating
Unrelated species evolve similar traits because they live in similar niches or have similar lifestyles. (2 words)
Convergent Evolution

What are homologus structures
This principle of Natural Selection states that individuals in a population will show differences
Variation
A massive amount of evidence from many different fields such as genetics, chemistry, paleontology, and mathematics, overwhelmingly suggest that all living things share a ________ ________ (two words)
common ancestor
Certain individuals in a population have a higher survival and reproduction rate.
Natural selection
Diversification of a species into a number of different species is known as... (2 words)
Divergent evolution
body part that shares a common function but not a common structure
the study of past and present distribution of organisms
(where organisms are located all over the world)
biogeography
Islands, a large river, canyon or other barrier can cause an organism to develop different species
What is geographic isolation
Random change in the allelic frequency in a population, caused by something that shrinks a population size is called ... (2 words)
Genetic Drift
The situation which allele frequencies in the gene pool of a population remain constant
genetic equilibrium
