Natural Selection and Adaptations

1. The process of choosing parent organisms for desired characteristics is called

• natural selection

• Artificial selection

• random selection

• genetic manipulation

What is an example of artificial selection?

• Letting dogs choose their own mate

• Letting plants pollinate on their own

• Crossing a labrador and a poodle to create a labradoodle

Which statement is true comparing natural selection and artificial selection?

• In natural selection, traits benefit humans and in artificial selection, the traits benefit the species

• In natural selection, traits benefit the species and in artificial selection, the traits benefit humans

• In natural and artificial selection, the process takes hundreds of years to occur

• In natural and artificial selection, nature determines what traits will be passed down to offspring.

Artificial selection is also known as

• natural selection

• selective hearing

• genetic manipulation

• selective breeding

The primary difference natural and artificial selection is

• In nature selection the “pressure” comes from the environment; In artificial selection the “pressure” comes from humans (or another species).

• In artificial selection the “pressure” comes from the environment; In natural selection the “pressure” comes from humans (or another species).

• Natural selections is when humans breed the animal; Artificial selection is when humans direct genes directly.

• They are different terms for the same concept.

These cause variations.

• mutations

• adaptations

• a desire to change

• breeding

Artificial selection is also known as surivial of the fittest.

• True
• False

1. Artificial selection has been a big factor in the evolution of:

• Dogs

• Panda bears

• Snakes

• Jellyfish

What is the process where animals live or die based on their adaptations to their environment.

• Genetic Drift

• Natural Selection

• The Circle of Life

• Mammoth

Process by which individuals that are better suited to their environment survive and reproduce most successfully; also called survival of the fittest.

• Extinction
• Speciation
• Natural Selection
• Artificial Selection
