Evidence of Evolution

Front

What is evidence of evolution?

Back

Evidence of evolution refers to the various types of data and observations that support the theory of evolution, including fossil records, genetic similarities, and anatomical structures.

Front

What does a very similar DNA sequence indicate about two organisms?

Back

It indicates that the two organisms are closely related and share a common ancestor.

Front

What are adaptations?

Back

Adaptations are traits or characteristics that enhance an organism's ability to survive and reproduce in its environment.

Front

Define a biological species.

Back

A biological species is a group of interbreeding populations that are reproductively isolated from other groups.

Front

What is a vestigial structure?

Back

A vestigial structure is a body part that has lost its original function through evolution, such as the tailbone in humans.

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 the significance of fossil records in evolution?

Back

Fossil records provide evidence of past life forms and show how species have changed over time.

Front

What is the role of mutations in evolution?

Back

Mutations introduce genetic variation, which can lead to new traits that may be beneficial for survival.

Front

What is the concept of common descent?

Back

Common descent is the idea that all living organisms share a common ancestor from which they have evolved.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures are similar due to shared ancestry, while analogous structures are similar due to convergent evolution, not common ancestry.
