Biological Change Over Time

These flashcards cover key concepts pertaining to biological change over time, focusing on evolution, species definitions, mutations, and selection processes.

Evolution

The process by which species change over time.

Species

A group of organisms capable of interbreeding and producing fertile offspring.

Hybrid

An offspring produced from the mating of two different species.

Fitness

A measure of an individual's reproductive success.

Mutation

A change in a gene or allele that can create variations among species.

Harmful Mutation

A mutation that reduces reproductive success and is selected against.

Beneficial Mutation

A mutation that improves reproductive success and is favored.

Neutral Mutation

A mutation with no impact on reproductive success.

Artificial Selection

The process by which humans select individuals for reproduction based on desired traits.

Genetic Diversity

The variety of genes within a species, which is essential for adaptability.
