What is embryology?

Back

The earliest growth stage of development.

Front

How does embryology support the Theory of Evolution?

Back

It shows that embryos who develop similarly share a common ancestor.

Front

What effect can bottleneck events have on populations that have nearly become extinct?

Back

Bottleneck events reduce the size of the population and greatly reduce genetic variation.

Front

Which of the following is not a piece of evidence for evolution?

Back

Fossil age.

Front

An organism's ability to survive and reproduce in its environment refers to its:

Back

Fitness.

Front

What are homologous structures?

Back

Anatomical features in different species that share a common ancestry.

Front

What is the founder effect?

Back

A reduction in genetic diversity that occurs when a small group of individuals establishes a new population.

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 are vestigial structures?

Back

Body parts that have lost their original function through evolution.

Front

What is genetic variation?

Back

Differences in DNA among individuals within a population.
