According to the theory of natural selection, some individuals more likely than others to survive and reproduce because they:

are better adapted to their environment than others and will pass on those adaptations to future offspring.

pass on to their offspring their newly acquired traits.

do not pass on newly acquired traits.

produce fewer offspring than others in the same environment.

What is the advantage of having different shaped beaks?

To be able to eat the food readily available in the environment.

To look different from other species.

To protect itself against predators.

To protect itself against prey.

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

Humans select which animals live and die

The theory of evolution by natural selection means that what is changing over time?

The inherited traits of a population.

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

Because they are more likely to survive and reproduce.

Because they come from dominant alleles.

Because they come from recessive alleles.

Because the trait is an acquired phenotype.

Why is the mouse population changing over time?

The hawks eat more light mice than dark mice because they can see the light mice more easily

The light mice can reproduce more successfully than the dark mice

The hawks eat more dark mice than light mice because the dark mice taste better

The hawks eat more dark mice than light mice because they can see the dark mice more easily

Mutations are important because they bring about

genetic variation needed for a population to evolve

death of the organism in which they develop

benefits for the individual, not for the population

Hardey-Weinberg equilibrium within a population

Species have evolved into two different species when...

the populations can no longer interbreed

the populations are separated geographically

Which adaptation (for the underlined animal) serves the function of defense?

A porcupine’s quills cause a predator to seek another meal.

A walking stick looks like the twig on which it rests.

A whale filters plankton and krill from the water in which it swims.

A penguin is dark on top and white below to blend in with the water.

How do jackrabbits adapt to the desert heat?

They release heat through their long ears to stay cool.

Why do nocturnal animals hunt at night?

The desert is hot during the day so they go to their burrows and dens until it is cooler.

A group of organisms that can mate with each other and produce fertile offspring.

A group of organisms that can mate and produce offspring even if those offspring are infertile.

A group of organisms that genetically are very different from each other.

Indivual organisms that live in the same environment.

Variation happens as a result of the exchange of genetic information as it is passed from parent to offspring. Which of the following is true about inherited variation?

Variation can influence whether organisms are more likely to survive to reproduce.

Variation can influence separation.

Variation can influence selective breeding.

Variation can influence the resources that are available to an organism.

What are the spots on a fawn for?

Allows hunters to recognize the babies.
