Evolution Vocabulary

Descent with modification
Divergence in traits
Genetic change in a population or species over generations.
Evolutionary adaptation
An inherited characteristic that enhances an organism's ability to survive and reproduce in a particular environment.
A preserved remnant or impression of an organism that lived in the pas
Gene flow
The loss or gain of alleles in a population due to the migration of fertile individuals or gametes between populations.
Gene pool
The total aggregate of genes in a population at any one time
Genetic drift
Changes in the gene pool of a small population due to chance.
Anatomical similarity due to common ancestry.
Evolutionary change on a grand scale, encompassing the origin of new taxonomic groups, evolutionary trends, adaptive radiation, and mass extinction.
Mass extinction
A change in the gene pool of a population from generation to generation.
A rare change in the DNA of a gene ultimately creating genetic diversity
Natural selection
Differential success in the reproduction of different phenotypes resulting from the interaction of organisms with their environment. Evolution occurs when natural selection causes changes in relative frequencies of alleles in the gene pool.
Nonrandom mating
Population isolation
A group of individuals of one species that live in a particular geographic area.
Rate of evolution
Reproductive isolation
The origin of new species in evolution
A group whose members possess similar anatomical characteristics and have the ability to interbreed.
