Evolution Test Review

Modern frog larvae resemble primitive vertebrate larvae. This suggests these organisms

• evolved before frogs

• evolved from frogs

• are the same species as frogs

• share common ancestor with frogs

When species experience long stability and then are interrupted by brief periods of rapid evolutionary change.

• punctuated equilibrium

• adaptive radiation

• coevolution

• convergent evolution

Darwin found species that were distantly related and looked alike in different parts of the world because

• the species once lived in same place

• the species were closely related

• the species lived in similar environments

• the species lived in different environments

A population of bees becomes divided into different populations. The two populations will become separate species if the two populations are

• unable to interbreed

• able to produce lots of offspring

• different colors

The most accurate definition of Natural Selection is

• elimination of the small organisms by the bigger organisms

• survival and reproduction of organisms that are genetically best adapted to their environment

• survival and reproduction of organisms that occupy the largest area

• survival of the biggest and strongest organisms in a population

The pattern of evolution in which a species evolves at a slow and steady pace is known as

• gradualism

• adaptive radiation

• punctuated equilibrium

• survival of the fittest

Which of the following is the best example of an organism with a genetic variation improving their survival over time?

• cactus with no spines

• fish with aquatic illness

• rat who's learned to avoid traps

• a roach that is resistant to pesticide

The theory of Natural Selection says individuals who survive are best adapted for their environment. What is their survival due to?

• choices made by plant and animal breeders

• lack of competition in their environment

• possession of adaptations developed through their use in their lifetime

• possession of inherited adaptations that maximize fitness

A seed eating bird has a strong beak that helps crack the seeds. This is an example of:

• a vestigial organ

• a fossil

• an adaptation

• an unnecessary body part

True or False: Natural selection increases the fitness of a population.

• TRUE

• FALSE
