descent with modification

natural selection

mimicry

Natural selection acts on ____, not ____.

individuals, populations

populations, individuals

What does it mean for an individual to be "fit"?

high likelihood of becoming fossilized

has multiple habitats

makes more healthy offspring

has more mates

What explains why individuals develop certain traits? (i.e. long neck in giraffes, colorful feathers in peacocks, webbed feet in ducks)

they are beneficial to them and make them more fit

they help them acquire more food

they make them easier to fossilize

they are easier to pass down to offspring

What is the cause of ALL genetic variation?

mutations

evolution

adaptations

non-random mating

Process of mating specific organisms to create offspring with desired traits

natural selection

random mating

selective breeding

evolution

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

natural selection

mutation

camouflage

adaptation

How do you "win" at natural selection?

survive

go extinct

survive & reproduce

Which organisms are most likely to survive?

10.

The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment?

Dark moth

Light moth

Both will be equally successful

Neither will be successful

11.

These moths are all the same species. The differences between their wings is an example of ________________

Natural Selection

Variation

Homeostasis

Extinction

12.

Which of the following explains adaptation.

An individual organism changes to meet its needs in the environment. These changes pass down to their offspring.

The species as a whole changes their characteristics.

Beneficial traits allow organism to survive and pass on those traits

New characteristics arise in a species as needed. If these traits are helpful, they are passed down.

13.

Evolution works by

individuals changing to suit their environment

Individuals learned new traits and pass them on

sudden change in the environment cause a species change

small changes pass down through many generations

14.

Mutations are important because they bring about

death of the organism in which they develop

genetic variation needed for a population to evolve

benefits for the individual, not for the population

Hardey-Weinberg equilibrium within a population

15.

19.

Which of the following is a factor in natural selection?

Individuals of species compete with one another to survive.

All species are genetically diverse.

Individuals better able to adapt to changes leave more offspring.

All are correct

20.
