Natural selection - amplify

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 role do genes play in determining traits?

Back

Genes are instructions for making protein molecules, and these proteins determine the traits of an organism.

Front

How can environmental changes lead to evolution?

Back

Environmental changes can create new challenges or opportunities, leading to changes in the traits that are advantageous for survival.

Front

What is an adaptive trait?

Back

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

Front

What is a non-adaptive trait?

Back

A non-adaptive trait is a characteristic that does not provide any advantage in terms of survival or reproduction.

Front

How does the height of giraffes relate to natural selection?

Back

Giraffes with taller heights may have better access to food in trees, leading to a higher chance of survival and reproduction.

Front

What happens to a population when the environment becomes colder?

Back

If the environment becomes colder, traits that provide insulation or warmth, such as thicker fur, may become more common in the population.

Front

What is the significance of genetic variation in a population?

Back

Genetic variation is crucial for natural selection, as it provides the raw material for evolution by allowing some individuals to be better suited to their environment.

Front

How does competition affect natural selection?

Back

Competition for resources can lead to natural selection, as individuals with advantageous traits are more likely to survive and reproduce.

Front

What is the difference between evolution and adaptation?

Back

Evolution is the change in the genetic makeup of a population over time, while adaptation refers to the process by which a species becomes better suited to its environment.
