Natural Selection

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 geographical isolation?

Back

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

Front

What is adaptation in the context of natural selection?

Back

Adaptation refers to a physical trait or characteristic that enhances an organism's ability to survive and reproduce in its environment.

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 is genetic isolation?

Back

Genetic isolation occurs when populations of the same species do not interbreed due to various barriers, leading to reduced gene flow.

Front

How do light colored tree trunks affect moth populations?

Back

Light colored tree trunks favor light colored moths, as they are better camouflaged from predators in that environment.

Front

What is the role of mutation in evolution?

Back

Mutation introduces new genetic variations into a population, which can be acted upon by natural selection.

Front

What is the significance of 'survival of the fittest'?

Back

'Survival of the fittest' refers to the idea that individuals with traits better suited to their environment are more likely to survive and reproduce.

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 behavioral isolation?

Back

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