Natural Selection, Classification, Kingdoms Review

His time spent on the HMS Beagle in the 1800s allowed Charles Darwin to formulate the theory of

• natural selection

• adaptation by genetics

• speciation by isolation

• natural adaptation

Darwin's theory of natural selection states

• those best adapted to their enviornment are more likely to survive and reproduce

• those best adapted to their enviornment are always guaranteed to survive and reproduce

• those best adapted to their enviornment are more likely to pass on dominant traits

• those best adapted to their enviornment are guaranteed to pass on alleles that code for a new trait

Which of the following words describe a trait that helps an organism survive in its environment?

• natural selection

• mutation

• genetic behavior

• adaptation

According to Darwin, which organisms are most likely to survive and reproduce?

• the best adapted

• the fastest

• the strongest

• the smartest

The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this current environment?

• Dark moth

• Light moth

• Both will be equally successful

• Neither will be successful

When an environment changes faster that an species can adapt, the most likely outcome is

• abiotic dominance

• voluntary mutation

• species extinction

• selective breeding

Which of true about mutations?

• They lead to the extinction of the population due to the sudden change.

• They lead to genetic variation needed within a population.

• They benefit the individual, not for the population.

• They are purposeful changes in DNA due to a changed enviornment.

Darwin says a species may use overpopulation

• to ensure extinction does not occur

• to use all resources in the enviornment

• to compete with prey

• to mutate in order to compete

Charles Darwin observed finches on the Galápagos Islands and concluded

• all of the answers are correct

• each bird acquired its traits through selective breeding

• the birds all ate the same type of food

• similar birds had different beaks

Which of true about sexual reproduction?

• Offspring are identical to the parents.

• It leads to genetic variation needed within a population.

• It is essentially a method of cloning.

• It causes mutations within each offspring.
