EVOLUTION review

When a predator hunts its prey, some will survive.  How is this concept like Natural Selection?

• survival of the fittest
• descent with modification
• reproductive isolation
• acquired characteristics

What factor determines if a mutation will continue in a population?

• Humans have chosen the trait
• the trait is similar to others
• it adds to the population
• increase survival in an environment

The theory of evolution suggests that...

• different species can interbreed.
• extinct species are not related to living species.
• species changes over long period of time.
• species that look alike are most closely related.

According to natural selection, organisms survive have...

• traits from their parents acquired.
• traits that humans selectively bred.
• traits that are best suited in the environment.
• the greatest number of offspring.

The ability of an organism to survive and reproduce in its specific environment

• fitness.
• evolution.
• adaptation.
• diversity.

What is true of Darwin's theory of evolution?

• Characteristics that are inherited are the cause of evolution.
• Organisms that are the fittest are larger and stronger
• The number of offspring is not related to fitness
• The more offspring are produced  that can possibly survive.

Larmark's theory of _________ says giraffes stretched their necks and passed on the trait.

• natural selection
• origin of species
• acquired traits
• artificial selection

What are structures that are the same embryonic tissue but different in mature organism?

• vestigial
• homologous
• bones
• limbs

Evolution is...

• a process that explains modern organisms.
• human selecting traits in dog breeds.
• a quick process of changing.
• acquired traits in one's lifetime.

Darwin's observations of Galapagos Finches showed...

• that they flew and spread.
• beak shapes and sized depended on their food.
