Evolution Test

Front

What is DNA?

Back

DNA (deoxyribonucleic acid) is the molecule that carries the genetic instructions for life and is responsible for the inheritance of traits.

Front

What does it mean when two species have similar DNA?

Back

It suggests that they likely evolved from a common ancestor.

Front

What is evolution?

Back

Evolution is the change in the characteristics of a species over time through processes such as natural selection and genetic variation.

Front

What is adaptation?

Back

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

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 variation in the context of evolution?

Back

Variation refers to the differences in traits among individuals in a population, which can lead to evolutionary changes.

Front

What is gradualism in evolution?

Back

Gradualism is the theory that evolution occurs slowly and steadily over long periods of time.

Front

What are intermediate forms?

Back

Intermediate forms are fossils or organisms that show traits between two different species, providing evidence for gradual evolution.

Front

Can individual organisms evolve?

Back

No, individual organisms do not evolve; evolution occurs at the population level over generations.

Front

What is a common ancestor?

Back

A common ancestor is an ancestral species from which two or more different species have evolved.
