A bird's beak allows it to crack open hard nuts.

A zebra's stripes allow it to confuse its predators.

A frog's large hind legs allow it to jump from danger.

Change over time in a population.

That everything is the same.

That organisms never change.

Negative traits are acquired in populations.

The inherited traits of a population.

The acquired traits of a population.

Hair color and eye color

Attractive features.

pass on to their offspring their newly acquired traits.

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

do not pass on newly acquired traits.

produce fewer offspring than others in the same environment.

They evolved from a common ancestor.

They all came from different continents.

they evolved from 13 different types of birds.

they developed from other types of organisms.

selection; underproduction of offspring; homeostatsis; fossil records

underproduction of offspring; genetic variation; extinction; adaptation

adaptation; inconsistency; sexual reproduction; energy use

overproduction of offspring; genetic variation; struggle to survive; successful reproduction

Ability to find food.

Ability to avoid predators

Ability to find a mate. 

All of the above.

All of the lizards would try to develop new traits to avoid the new predator.

Some of the lizards would try to develop new traits to avoid the new predator, and the other lizards would die.

The lizards that already have the traits needed to avoid the new predator would be more likely to survive and reproduce, and the ones that do not would be less likely to survive and reproduce.

Because all lizards of the same species have the same traits, one lizard would not have an advantage over another lizard. They would either all survive or all die.

Members of the same species compete with one another for resources.

Variation exists among individuals in a species

A sudden environmental change.

Traits are inherited from one generation to the next.

sorting of chromosomes during sexual reproduction 

combining of chromosomes during organ development 

removal of chromosomes during selective breeding

changing of chromosomes during cloning 

 reproduction            

natural selection

mouse extinction

An external factor which affects an organism’s ability to survive in a given environment

The organisms DNA which affect the organism’s ability to survive in a given environment

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

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

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 light mice than dark mice because they can see the light mice more easily

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

Natural selection only occurs in prokaryotic cells

Insects and bacteria can reproduce faster than more complex organisms and pass on selected traits quicker

Insects were the first multi-cellular organism to live on land

Bacteria have directly evolved from insect traits.

The antlers and horns are structural adaptations, and the fighting is a behavioral adaptation.

 These mammals are carnivores that use their antlers to attack and kill their prey.

Antlers are examples of behavioral adaptations used by Moose and Deer

Deer and Moose antlers are structural adaptations, but horns are not. 

The deer stopped competing for resources because they had no predators.

The increased number of deer led to increased competition for resources.

A large number of deer left the region in search of new predators.

The removal of predators caused fewer resources to be available to the deer.

Mutations help an organism to better survive in their environment

An organism may acquire a helpful mutation by interacting with the environment

A mutation may result in an adaptive trait that makes an organism more likely to survive and reproduce

Organisms with certain traits are more likely to win competitions for mutations

It shows which variations are more successful, allowing the organisms with those variations to survive.

It causes organisms, regardless of which traits they have, to die out, reducing the population size.

It causes organisms to get stronger due to having to outcompete other species.

Competition is not important for natural selection.

The inherited traits of a population.

The acquired traits of a population.
