NY Regents Life Science: Biology Module 5 evolution overview quiz quiz

Organisms choosing to develop traits

The environment directly changing traits

Mutation, reshuffled by sexual reproduction

Use and disuse of body parts

All individuals survive equally

Organisms try to adapt, then pass on the effort

Variation exists, overproduction causes competition, the better-suited survive and reproduce, and they pass on their traits

The environment creates the traits that are needed

Light beetles turned dark during their lives

Dark beetles were better camouflaged, so they survived and reproduced more, passing on dark-color alleles

The beetles decided to turn dark

The predator changed the beetles' DNA

Structures found only in fossils

Structures that look identical and do the same job

Structures with no shared ancestry

Structures with the same basic plan but possibly different functions

All species have identical DNA

DNA changes randomly with no pattern

DNA is not inherited

The more similar the DNA, the more recently the species likely shared a common ancestor

By which two share the most recent common ancestor (branches join closest to the present)

By how close their tips are drawn

By reading left to right

By the length of their names

Different species descended from the same ancestral species

All species are unrelated

Each species arose separately and recently

Species never change

The population becomes reproductively isolated so the groups can no longer interbreed

All individuals become identical

The species becomes extinct

The two groups interbreed more

They eat the same food

They live in the same place

They can no longer interbreed to produce fertile offspring

They look slightly different

It has no predators

It has too much genetic variation

It reproduces too successfully

The environment changes faster than the species can adapt, so too few survive

It guarantees every individual survives

It makes it more likely some individuals have traits suited to the new conditions and survive to reproduce

It prevents any change in the population

It stops mutations from occurring

Only the climate of an area

Species diversity (variety of species) and genetic diversity (variation within a species)

Only the largest organisms present

Only the number of animals

Diverse crops cannot be infected at all

If the disease can affect one plant it can affect all, since the plants are genetically identical

Uniform crops grow faster

Uniform crops have more variation

Other species can fill the roles of any that decline, so the ecosystem keeps functioning

It cannot change at all

It depends on a single species

It has fewer interactions
