What is Darwin's theory of natural selection?

Back

Darwin's theory of natural selection explains how species change over time to survive in their environment. It is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What happens as populations grow?

Back

As populations grow, competition for resources increases among individuals.

Front

What is relative dating in fossils?

Back

Relative dating is a method used to determine the age of fossils based on their depth in the ground, comparing their position to other layers.

Front

How are traits passed down in organisms?

Back

Traits are passed down to offspring through genes inherited from their parents.

Front

What did Darwin conclude about common ancestors?

Back

Darwin concluded that common ancestors explain the similarities in species, such as the different beak shapes of finches.

Front

What is natural selection?

Back

Natural selection is the process where organisms with favorable traits are more likely to survive and reproduce.

Front

What is competition in ecology?

Back

Competition occurs when individuals or species vie for the same resources, such as food, water, or space.

Front

What is the significance of a common ancestor?

Back

A common ancestor is significant because it provides evidence for the evolutionary relationships between different species.

Front

What is the difference between relative dating and radiometric dating?

Back

Relative dating determines the age of fossils based on their position in layers of rock, while radiometric dating uses the decay of radioactive isotopes to determine an exact age.

Front

What role do genes play in evolution?

Back

Genes carry the traits that can be passed down through generations, influencing the evolution of species.
