What is the theory of evolution through natural selection?

Back

The theory proposed by Charles Darwin that explains how species evolve over time through the process where organisms better adapted to their environment tend to survive and produce more offspring.

What are vestigial structures?

Back

Structures that were once functional in the past but no longer serve a purpose due to evolutionary adaptations and physiological changes.

What are analogous structures?

Back

Structures in different species that serve similar functions but do not share a common ancestry.

What is the significance of genetic variation in evolution?

Back

Genetic variation provides the raw material for natural selection to act upon, allowing populations to adapt to changing environments.

What role does mutation play in evolution?

Back

Mutations introduce new genetic variations into a population, which can lead to new traits that may be beneficial for survival.
