A theory of evolution proposing that traits acquired during an organism's life can be passed to offspring.

A process where organisms better adapted to their environment tend to survive and produce more offspring.

The change in the heritable characteristics of biological populations over successive generations.

A visual display that organizes information and ideas.

Situations that relate personal or societal changes to the process of evolution.

Working together with others to complete tasks or learn concepts.

The process by which a species becomes better suited to its environment.

The state of continuing to live or exist, especially in difficult conditions.

The theory of evolution by natural selection developed by Charles Darwin, emphasizing survival and reproduction of the fittest.

The variety and variability of life forms within a given ecosystem or the entire planet.

Methods that species use to survive in their environments, such as adaptation and competition.

Understanding evolution is crucial for recognizing how species develop and adapt over time.

Proposed that organisms could pass on traits acquired during their lifetime.

Focused on the idea of common descent and natural selection as the mechanism of evolution.

A group of organisms capable of interbreeding and producing fertile offspring.

A community of living organisms and their interactions with the environment.
