Definition
Natural Selection
Term
Changes in organisms over long periods of time.
Definition
Biological evolution or evolution
Term
List the two types of evolution.
Definition
Microevolution and macroevolution
Term
A type of evolution that occurs on a small scale affecting a single popultaion.
Definition
Microevolution
Term
Large scale evolution that affects larger groups with brancing out of new species.
Definition
Macroevolution
Term
Five sources of microevolution:
Definition
mutations
natural selection
gene flow
genetic drift
nonrandom mating
Term
Changes in DNA
Definition
Mutation
Term
Movement of alleles between populations.
Definition
Gene Flow
