Evolution and Natural Selection Test Review

Who proposed the modern theory of evolution?

• Francis Crick

• Robert Hooke

• Charles Darwin

A change in the hereditary features of a group of organisms over time is called:

• mutation

• evolution

• natural selection

Any difference between individuals of the same species is called:

• a variation

• competition

• adaptation

An adaptation is any trait that helps an organism:

• survive and reproduce

• live longer without reproducing

• overproduce variations

What did Charles Darwin observe about the finches in the Galapagos Islands?

• Their feathers were adapted to match their environment

• Their beaks were adaptations related to the foods the finches ate

• They had identical phenotypes in all locations

What was Darwin's job on the HMS Beagle?

• study the formation of the Galapagos Islands

• learn about and collect the living things he saw on the voyage

• make a map of the world

Variations found within species are caused by:

• adaptations

• sexual reproduction and mutations

• competition

Darwin concluded that the 13 species of finches on the Galapagos Islands:

• were identical to 13 finch species in northwestern South America 600 miles to the east

• evolved from one or two ancestral South American species

• had all adapted to the same food source

"Survival of the Fittest" is another way to say:

• overproduction

• natural selection

• competition

Many of the organisms that once lived on the planet are now extinct. All of these species became extinct because:

• the species did not adapt to survive changing environmental conditions

• of a major natural disaster that completely wiped out the species

• the species habitat was destroyed by human causes like pollution and logging
