The Scientific movements leading to Evolutionary Psychology Chp 1

Question 1

Evolution

Answer 1

change in organic structure over time

Question 2

Lamarack’s Proposed causes of evolution

Answer 2

-natural tendency for species to progress toward a higher form

-inheritance of acquired characteristics

Question 3

natural selection

Answer 3

among the range of inherited trait variations, those that lead to increased survival will most likely be passed on to succeeding generations

Question 4

3 necessary conditions

Answer 4

variation
inheritance
consequences

Question 5

3 ingredients in evolution

Answer 5

variation in organisms

consequences for these variations (how did the slight variation improve or impede the individual’s chances of reproducing and surviving?)

Heritability

Question 6

Directional selection

Answer 6

features in the original population move over time in a different direction

Question 7

stabilizing selection

Answer 7

selection pressures favoring an average characteristic over extremes

Question 8

artificial selection

Answer 8

a process where humans intentionally choose specific individuals with desired traits to be parents of the next generation. It is a form of selective pressure imposed by humans rather than natural environmental factors.

Question 9

sexual selection

Answer 9

a specific form of natural selection that involves the differential mating success of individuals based on their inherited characteristics. It can lead to the development of traits that enhance an organism’s ability to attract mates, even if those traits do not necessarily improve survival.
