Front

What is adaptation?

Back

A trait that helps an organism survive in its environment.

Front

What is artificial selection?

Back

The practice by which humans select plants or animals for breeding based on desired traits.

Front

What is the true statement about evolution?

Back

Evolution occurs over multiple generations.

Front

What does it mean when we say species descended from a common ancestor?

Back

It means that different species share a common lineage and have evolved from a single ancestral species.

Front

What is an analogous structure?

Back

Structures that have the same function but different structures/forms.

Front

What is a homologous structure?

Back

Structures that are similar in form but may serve different functions, indicating a common ancestry.

Front

What is natural selection?

Back

The process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is mutation?

Back

A change in the DNA sequence of an organism that can lead to new traits.

Front

What is the significance of the Galápagos finches in evolution?

Back

They illustrate how species can adapt to different environments and evolve from a common ancestor.

Front

What is the difference between evolution and adaptation?

Back

Evolution is the change in populations over generations, while adaptation refers to specific traits that enhance survival.
