How does natural selection work?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is the role of adaptation in evolution?

Back

Adaptation is a trait that helps an organism survive and reproduce in its environment, leading to evolutionary changes over time.

What is the significance of the fossil record?

Back

The fossil record provides evidence of past life forms and shows how species have changed over time.

Front

What is the difference between artificial selection and natural selection?

Back

Artificial selection is the process by which humans breed plants and animals for specific traits, while natural selection occurs without human intervention.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence of an organism, which can lead to new traits.

Front

What is the concept of survival of the fittest?

Back

Survival of the fittest refers to the idea that individuals with traits better suited to their environment are more likely to survive and reproduce.

Front

What is camouflage?

Back

Camouflage is a trait that allows an organism to blend in with its environment, helping it avoid predators.
