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 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 for survival or reproduction.

Front

How can environmental changes affect traits in a population?

Back

Environmental changes can lead to shifts in which traits are considered adaptive, causing populations to evolve over generations.

Front

What is the significance of spine size in cactuses?

Back

Spine size in cactuses can determine their ability to survive in different environments, with medium spine size becoming a non-adaptive trait in certain conditions.

Front

How does the environment influence the evolution of species?

Back

The environment can create pressures that favor certain traits over others, leading to changes in the population's characteristics over time.

Front

What happens to giraffes' height in a protected environment?

Back

Giraffes' height may increase over generations in a protected environment due to the absence of predators and availability of resources.

Front

What is the role of predators in natural selection?

Back

Predators can influence which traits are adaptive by preying on individuals with less favorable characteristics.

Front

What is an example of an adaptive trait in guppies?

Back

In guppies, medium spot size can be an adaptive trait that helps them survive in certain environments.

Front

How do populations adapt to colder environments?

Back

Populations may evolve traits such as thicker fur or fat layers to better survive in colder environments.
