Natural Selection

Front

What is natural selection?

Back

Natural selection is the process by which individuals that are better suited to their environment survive and reproduce most successfully, also known as survival of the fittest.

Front

What are variations?

Back

Variations are slight differences in inherited traits between individual members of the same species, such as fur color in rabbits.

Front

What is evolution?

Back

Evolution is the process in which populations change over time, often as a result of natural selection.

Front

What are adaptations?

Back

Adaptations are traits that enhance an organism's ability to survive and reproduce in its environment.

Front

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

Back

'Survival of the fittest' refers to the idea that individuals best adapted to their environment are more likely to survive and reproduce.

Front

What is an example of a variation in a species?

Back

An example of a variation is the different fur colors in rabbits, such as white and black.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures are similar due to shared ancestry, while analogous structures are similar due to convergent evolution, not shared ancestry.

Front

What is speciation?

Back

Speciation is the process by which new species arise from existing species, often due to evolutionary changes.

Front

How do environmental changes affect natural selection?

Back

Environmental changes can alter the survival and reproductive success of organisms, leading to changes in the population over time.

Front

What role does genetic variation play in natural selection?

Back

Genetic variation provides the raw material for natural selection, allowing some individuals to be better adapted to their environment.
