The embryos of different organisms share very few traits.

The embryos of different organisms have many traits in common.

The embryos of some organisms never develop into adults.

All embryos have the same DNA, even when they are from different organisms.

They show that horses have looked the same throughout history.

They show that horses became smaller over time.

They show that horses today are more intelligent than those in the past.

They show that horses' traits have slowly changed over time.

Each brain region performs the same function.

Different brain regions specialize in recognizing, feeling, and acting.

The spinal cord sends signals to all parts of the brain.

Reflex pathways replace brain processing.

They can change in response to experience and learning.

They only change when we feel fear.

They cannot create new neural pathways after early childhood.

They are made of plastic.

A reflex arc is based on prior experience and emotion.

A reflex arc is not processed in the brain.

A reflex arc does not involve neurons.

A reflex arc does not protect the organism.

The sun

The preferences of individual organisms

Changes in the environment

A population with no genetic variation

Genetic variation

Human interaction with the environment

A cell nucleus

Sexual reproduction

Survival of an entire species

Survival of organisms with the most advantageous traits

Survival of non-native, invasive species

Survival of the weakest organisms

Cooperative hunting

Alarm calling

Shared parenting

Migration

Cooperation to care for young in the group

Communication

Competition for limited resources

Genetic variation

The behavior increases survival of other group members.

Alarm callers are protected by other group members.

The behavior has no cost.

Predators stop hunting when they hear the alarm calls.

Solitary living

No social behaviors

Reduced reproduction

Group behaviors

Group behavior is only learned, not inherited from parents through genes

Group behavior occurs in populations with no genetic diversity

Group behavior helps individuals, but not the population as a whole

Group behavior increases survival and becomes more common

Individuals adapt to survive in the new environment.

Species choose better habitats.

New species form immediately.

Resources become more available for some species.

Individual mosquitoes adapted to wetter conditions during their lifetimes.

Water availability created favorable breeding conditions.

Other species became extinct.

Mutations increased suddenly.

It causes individuals to adapt.

It stops natural selection because all individuals stop reproducing.

It reduces gene flow between populations.

It guarantees extinction.

It physically separated populations, preventing interbreeding.

It caused immediate genetic change in the majority of individual squirrels.

It increased mutation rates.

It eliminated predators.

Two different populations are divided by a river and begin to develop different traits.

Different populations develop different mating calls and do not recognize each other.

Individuals do not compete for food and other resources.

Traits change during an individual organism's lifetime, and that individual can no longer reproduce.

Individuals adapt immediately.

Populations may diverge and form new species.

All populations become extinct.

The population will overshoot its carrying capacity.

Carnivorous

Retractable claws

Purring

They have no traits in common

It shows that all organisms have exactly the same DNA.

It shows that other organisms produce cytochrome c in a very different way than humans.

It shows that some organisms have very similar DNA, suggesting they have common ancestors.

It shows that cytochrome c is not made out of amino acids.

All beetles are the same size.

Individuals beetles are multiple colors.

Some beetles are green and some are brown.

Some beetles taste better to the birds than others.

Parents can pass it to their offspring through their genes.

Each beetle chooses what color it wants to be based on the environment it lives in.

Different beetles are different colors.

The green beetles are always more likely to survive than the brown beetles.

The brown beetles will survive and reproduce more because the birds do not like how they taste.

The brown and green beetles will survive and reproduce in equal numbers because parents will continue to pass on both traits to their offspring.

Individual green beetles will change their color to brown to camouflage better and survive.

The brown beetles will survive and reproduce more because they have an advantageous trait that allows them to camouflage from predators.
