Multiple Choice Occurence of Evolution

The following are Genetic basis of evolution EXCEPT.

• A. Synthetic theory

• B. Natural Selection

• C. Allele Frequencies

• D. Population Genetics

Choose which scientist corresponds best with the statement: 
survival of the fittest

• Darwin 
• Lamarck
• Gregorio Fallopio

• Robert Hook

The theory believes that nature selects the trait that will or will not survive and that organisms with favorable traits or those who are best suited in the environment have a better chance of survival.

• A. Mutation

• B. Gene Drift

• C. Natural Selection

• D. Non-random mating

5. Those who survive will pass on their favorable traits to their offspring. After many years, the population will produce organisms with traits that are different from their ancestors. These conditions show ____________.

• A. Mutation

• B. Gene Drift

• C. Natural Selection

• D. Non-random mating

6. It is an evolution process in organism that are not closely related, because they must adapt to similar challenges in their habitats.

• 6. A. Coevolution

• 6. B. Microevolution

• 6. C. Adaptive Radiation

• 6. D. Convergent Evolution

7.Why does adaptive radiation occur?

• A. Species adapts to ecological pressures from the other species.

• B. Species evolves into several different species, each occupying a new environment.

• C. Species change when there is a need to survive sudden or abrupt environmental changes.

• D. Species adapts to survive and evolve in a relative short time

8. Jean Baptiste de Lamarck believed that giraffes before have short necks, but because of their need to survive and in order to reach tall trees for food, they kept stretching their necks until these became longer and able to reach taller trees. A. Theory of Needs C. Theory of Evolution B. Theory of Use and Disuse D. Theory of Acquired Characteristics

• A. Theory of Needs

• B. Theory of Use and Disuse

• C. Theory of Evolution

• D. Theory of Acquired Characteristics

9.Genetic drift is a change in the allele frequency of population due to ______. A. random chance C. artificial selection B. natural selection D. non-random mating

• A. random chance

• B. natural selection

• C. artificial selection

• D. non-random mating

This mechanism of evolution occurs when populations migrate.

• A. Gene flow

• B.. Speciation

• C. Genetic drift

• D. Natural Selection

Darwin’s primary contribution to biological theory was the idea that:

• A. genes are the units of inheritance.

• B. new alleles arise through mutation

• C. evolution is the change in gene frequencies over time.

• D. an important mechanism of biological evolution is natural selection.
