What is Natural Selection?

Back

Natural Selection is the process by which organisms that are better adapted to their environment tend to survive and reproduce more successfully than others.

Front

What drives Natural Selection?

Back

Natural Selection is driven by changes in the environment and the survival of the fittest.

Front

What is an Adaptation?

Back

An adaptation is an inherited trait that helps an organism survive and reproduce in its environment.

Front

What is the process by which organisms inherit advantageous traits?

Back

Natural selection is the process by which organisms inherit advantageous traits that tend to reproduce more successfully.

Front

What are Analogous Structures?

Back

Analogous structures are different structures that have a similar function but do not share a common ancestor.

Front

What are Homologous Structures?

Back

Homologous structures are structures that are similar in different species due to shared ancestry.

Front

What is a Vestigial Structure?

Back

A vestigial structure is a body part that has lost its original function through evolution.

Front

Where do adaptations come from?

Back

Adaptations come from mutations that give an organism an advantage in its environment and genetic recombination during meiosis.

Front

What is the role of mutations in evolution?

Back

Mutations are changes in DNA that can lead to new traits, some of which may provide a survival advantage.

Front

What is Genetic Recombination?

Back

Genetic recombination is the process during meiosis where genetic material is shuffled, leading to new combinations of traits.
