The process by which organisms better adapted to their environment tend to survive and reproduce.
Natural Selection
A change in the heritable traits of a population over time.
Evolution
The individual who proposed the theory of natural selection.
Charles Darwin
The process in which humans breed organisms for specific traits.
Artificial Selection
The random changes in a population's gene pool that can affect evolution.
Genetic Drift
The concept that organisms better adapted to their environment are more likely to survive and pass on their traits.
Survival of the Fittest
A heritable characteristic that increases an organism's ability to survive and reproduce.
Adaptation
The process in which a DNA gene is damaged or changed, creating potentially beneficial variations in an organism's genetic code.
Mutation
A reduction in genetic diversity that results from a small number of ancestors.
Founder Effect
An extreme example of genetic drift that happens when the size of a population is severely reduced.
Bottleneck Effect
The exchange of genes between two populations.
Gene Flow
The formation of new and distinct species in the course of evolution.
Speciation
The total number of fossils and their placement in rock formations and sedimentary layers; used as evidence for evolution.
Fossil Record
A type of natural selection where individuals with certain inherited traits are more likely than other individuals to obtain mates.
Sexual Selection
The concept that all living organisms share a common ancestor.
Common Ancestry
The location where Charles Darwin made observations that contributed to his theory of natural selection.
Galapagos Islands
The reproductive success of an organism relative to the population.
Fitness
A phenomenon in which bacteria evolve in response to the use of medicines, demonstrating natural selection.
Antibiotic Resistance
Structures that have no apparent function and appear to be residual parts from a past ancestor.
Vestigial Structures
Structures in different species that are similar because of common ancestry.
Homologous Structures
The field of biology today, which is heavily influenced by the principles of evolution.
