Unit 1 Quiz #2 REVIEW FOR QUIZ: Evolution (Natural Selection)

The evolution of beak shapes in Galapagos finches is a response to

• the bodies of water present

• the types of food available

• whether the populations interbreed

• the nutritional content of seeds

According to Darwin, evolution occurs

• in a response to use or disuse of a characteristic

• by punctuated equilibrium

• by natural selection

• within an individual's lifetime

The traits of individuals best adapted to survive become more common in each new generation because

• offspring without those traits do not survive

• organisms with those traits are more likely to survive and reproduce

• those individuals do not breed

• natural selection does not affect well-adapted individuals

In the study of the fossil record, scientists have learned that

• organisms do not evolve

• related organisms share similar DNA sequences

• modern whales descended from a four-legged mammal

• vertebrate embryos have some features in common

Natural selection is the process by which

• the age of the Earth is calculated

• organisms with traits well-suited to the environment survive and reproduce at a greater rate than other organisms

• acquired traits are passed from one generation to the next

• all of choices are correct

Homologous structures suggest that the organisms

• have a common ancestor

• all grow at different rates

• evolved slowly

• live for a long time

An analysis of the DNA from these organisms would indicate that

• their DNA is identical

• they all have tails

• their DNA sequences show many similarities

• the all have the same number of chromosomes

Strong evidence for evolution comes from

• forensic biology

• books

• works of philosophy

• the fossil record

Lamarck supported

• unchanging species

• use and disuse of traits

• convergent structures

• embryological homologies

Darwin theorized that natural selection is

• the mechanism of evolution

• how modern species have come to exist

• the explanation for beak varieties in finches

• all of the choices are correct
