Natural Selection

Where better adapted organisms survive to pass on their genes to their offspring

• Evolution

• Extinction

• Natural Selection

• Artificial Selection

Why are advantageous traits more likely to be passed onto its offspring?

• B/c they are more likely to survive and reproduce

• Because they have dominant genes

• Because they have recessive genes

• Because trait is an non adaptive trait

Do individual organisms decide to evolve?

• Yes

• No

Almost all adaptations start off as?

• Selective breeding

• physiological

• structural

• mutation

what word describes a trait that helps an organism survive in its current environment?

• natural selection

• mutation

• non adaptive trait

• adaptive trait

If a new trait does help an organism survive and reproduce, what may happen to it?

• it dies and its DNA is not passed on

• It survives and its DNA is passed on

• It changes its traits to adapt and survive

What happens to new traits that help organisms survive over time?

• They become more common

• They become less common

• There is no change

Mutations are change in what?

• RNA

• Protein

• Carbohydrates

• DNA

The differences among species, such as beak size and shapes among birds, are called

• genes

• variations

• traits

• theories

All rabbits living in a same environment is called

• community

• population

• species

• ecosystem
