Theory of Evolution

1.  Explain the theory of evolution.

     - Theory of evolution is proposed by Charles Darwin. The theory requires three condition; variation, selection and retention. Variation is that there are many species. Selection is that individual has different inheritance. Last, they have to have a retention of the selected traits from ancestors.

2.  Explain the “nature vs nurture” debate.

    - It is that although both of heredity and environment can affect on the human's mind,   the question is which one is more effective. As a result, they are viewed as competition.

3.  What is wrong with the concept of “nature vs. nurture”?

     - It is not a matter of nature and nurture. The competitive frameworks misread the way how the human traits come to be.

4.  What is meant by “social Darwinism”?

    - It is that competition and natural selection are basic power of social evolution. They rejected that it is from biology.

5.  Explain eugenics.

     - It is a effort to produce super human through selective breeding. It formalized the idea that we develop super dogs and roses.

6.  What is the problem with the concept of eugenics?

     - People misunderstand the concept of evolution. The problem is that the traits that people think it is good could combine with less-valued traits. Also, everyone is top of an equally long series of successful reproduction.

7. What does the term “fitness” mean in relation to evolution?

   - It is a basic mechanism of evolution. The greatest fit is remained and passed to next generation to survive, and less fit is disappeared.

8.  What is meant by “genetic determination”?

    - It is one of the persistent objection in psychology, and in biology, generally, it means if something found to be genetic, it cannot be changed. So, investigating genetic basis is dangerous.

9.  What is “fixation”?

     - The species are committed to it, so it is only changed by mutation. 

10.  What is “canalization”?

     - It is a phenomenon that the trait controlled by family of gene that produce same result.

11.  What is “punctuated equilibrium”?

    - It is the period of rapid evolution were colorfully terms. During the equilibrium, usually, the natural selection does not crease.

12.  How does evolution relate to psychology?

    - Evolution explains some psychological traits such as memories, perception, and adaptation.

13. Examine one evolutionary explanation of behavior.

    - The aggression helps animal to get food and access to the mates. Sometimes, they are aggressive to get territory and defend it. Also, human aggression may exist because of reproductive results from ancestors' aggressive behavior.
