What is natural selection?

Back

Natural selection is the mechanism by which individuals with favorable traits are more likely to survive and reproduce.

Front

What is an adaptation?

Back

An adaptation is an inherited trait that enhances an organism's ability to survive and reproduce in its environment.

Front

What is speciation?

Back

Speciation is the process by which new species arise from existing species due to genetic divergence.

Front

What is a common ancestor?

Back

A common ancestor is an ancestral species from which two or more species have evolved.

Front

What is geographic isolation?

Back

Geographic isolation occurs when a population is divided by physical barriers, leading to the formation of new species.

Front

What is behavioral isolation?

Back

Behavioral isolation occurs when two populations develop different mating behaviors, preventing them from interbreeding.

Front

What is temporal isolation?

Back

Temporal isolation occurs when two populations breed at different times, preventing them from mating.

Front

What is gametic isolation?

Back

Gametic isolation occurs when sperm and egg from different species are incompatible, preventing fertilization.

Front

What is fitness in evolutionary terms?

Back

Fitness refers to an organism's ability to survive and reproduce in its environment.
