Charles Darwin & Natural Selection

Front

What is competition in the context of natural selection?

Back

Competition refers to the struggle between organisms for the same resources, such as food, space, or mates, which can affect their survival and reproduction.

Front

Define adaptation in biological terms.

Back

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

Front

Give an example of adaptation in animals.

Back

The white feathers of a snowy owl allow it to blend in with the snow, providing camouflage from predators.

Front

What is evolution?

Back

Evolution is the process of genetic changes in a population over long periods of time, leading to the development of new species.

Front

What are the two key factors for an organism to be considered 'successful' in terms of survival?

Back

Survive and reproduce.

Front

What is variation in the context of natural selection?

Back

Variation refers to the differences in traits among individuals in a population, which can affect their survival and reproductive success.

Front

How does natural selection work?

Back

Natural selection is the process where organisms with favorable traits are more likely to survive and reproduce, passing those traits to the next generation.

Front

What role does the environment play in natural selection?

Back

The environment determines which traits are advantageous for survival and reproduction, influencing the direction of natural selection.

Front

What is a species?

Back

A species is a group of organisms that can interbreed and produce fertile offspring.

Front

What is the significance of genetic diversity in a population?

Back

Genetic diversity increases a population's ability to adapt to changing environments and resist diseases.
