Evolution (NGSS)

Front

What is variation in the context of evolution?

Back

Variation refers to the genetic differences between organisms of the same species.

Front

What is microevolution?

Back

Microevolution is the type of evolution that occurs on a small scale, typically within a single population, and does not lead to the formation of new species.

Front

What is macroevolution?

Back

Macroevolution refers to large-scale evolutionary changes that occur over long periods of time, often associated with the formation of new species.

Front

What does it mean when a species is considered extinct?

Back

A species is considered extinct when it completely dies out and no individuals of that species remain.

Front

What is evolution?

Back

Evolution is a change in the gene frequencies within populations or species over time.

Front

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 adaptation in evolutionary biology?

Back

Adaptation is a trait that helps an organism survive and reproduce in its environment.

Front

What is the significance of common ancestry in evolution?

Back

Common ancestry suggests that different species share a common ancestor, indicating how species have diverged over time.

Front

What role does embryology play in understanding evolution?

Back

Embryology studies the development of embryos, revealing similarities between different species that suggest common ancestry.

Front

What is biogeography?

Back

Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time.
