Natural Selection

Front

What is geographical isolation?

Back

Geographical isolation occurs when two populations of the same species are separated by physical barriers, such as rivers or mountains, preventing them from interbreeding.

Front

What is behavioral isolation?

Back

Behavioral isolation happens when two populations of the same species do not mate because they have different mating rituals or signals.

Front

What is a gene pool?

Back

A gene pool is the total collection of genes and their variations present in a population.

Front

What does Punctuated Equilibrium imply?

Back

Punctuated Equilibrium suggests that species experience rapid changes in response to catastrophic events, leading to accelerated natural selection.

Front

According to natural selection, what would light colored tree trunks favor?

Back

Light colored tree trunks would favor light colored moths, as they would be less visible to predators.

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is adaptive radiation?

Back

Adaptive radiation is the process by which a single ancestral species rapidly diversifies into a wide variety of forms to adapt to different environments.

Front

What is temporal isolation?

Back

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

Front

What is the significance of variation in a population?

Back

Variation in a population is crucial for natural selection, as it provides the raw material for evolution.

Front

What is the role of mutations in evolution?

Back

Mutations introduce new genetic variations into a population, which can lead to new traits that may be beneficial for survival.
