Natural Selection

Which is not an example of an adaptation?

• A bird's beak allows it to crack open hard nuts.
• A zebra's stripes allow it to confuse its predators.
• A frog's large hind legs allow it to jump from danger.
• A cat sleeps on the sofa to avoid the vacuum cleaner.

What is it called when better adapted organisms survive to pass traits along to their offspring.

• Evolution
• Natural Selection
• Extinction
• Artifical Selection

"Survival of the Fittest" describes which theory

• a) natural selection
• b) gravity
• c) heredity
• d) string theory

Why did the population of peppered moths in England change from light to dark after the Industrial Revolution?

• Light moths were easy to see against sooty trees and were eaten
• Light moths were killed by soot
• The birds that ate the dark moths were killed by soot
• Dark moths were produced by industrial processes

The example of the peppered (brown) moths living near English industrial cities demonstrates that

• A change in an environment can result in the evolution of species living there
• Evolution occurs so slowly that is it not possible to determine that it has happened in less than a million years
• The environment near these cities has always favored dark colored moths

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

Which organisms are most likely to survive?

• the best adapted
• the fastest
• the strongest
• the most domesticated (tamed)

Any inherited trait that gives an organism an advantage in its environment is called ___.

• a mutation
• an adaptation
• evolution
• natural selection

When every organism of a given species has died

• Natural Selection
• Homeostasis
• Extinction
• Selective Breeding

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 environment?

• Dark moth
• Light moth
• Both will be equally successful
• Neither will be successful
