Front

Evolution

Back

How modern organisms have descended from ancient ancestors, how organisms have changed over lots of time.

Front

Mutation

Back

A change in the DNA code.

Front

Processes of Evolution

Back

What causes changes in DNA code over long periods of time: mutation, migration (gene flow), natural selection, human impact.

Front

Gene Flow

Back

Also called migration, animals or plants (seeds) go from one place to another bringing genetic information.

Front

Natural Selection

Back

Survival of the Fittest, an organism born with a beneficial genetic change could survive better and pass on that benefit to offspring.

Front

Human Impact

Back

Gene therapy, cloning, artificial selection, GMO.

Front

Gene Therapy

Back

When genes are changed by scientists to help a person prevent or treat a disease.

Front

Cloning

Back

When all genes are copied in a living thing to make another exact copy of that organism.

Front

Artificial Selection

Back

When people choose which organisms get to pass on genetic information, the breeding of plants and animals to produce desirable traits.
