2.2 The Origin of Life, Theory of Natural Selection

Question 1

What concept of natural selection suggests that individuals conferred with different traits have better chances of survival within a population?

Answer 1

Variation

Question 2

What is the ability to produce numerous offspring than can survive?

Answer 2

Overproduction

Question 3

What concept of natural selection is represented by lack of resources, predation, disease, unfavorable environmental conditions, and competition?

Answer 3

Limits on population growth

Question 4

What concept of natural selection shows that organisms which have traits suited to the environment have a better chance of survival and can live long enough to REPRODUCE?

Answer 4

Differential reproductive success

Question 5

What principle suggest that evolutionary change is based on changes in the genetic makeup of POPULATIONS over time?

Answer 5

Individuals do not evolve, it is the population that does

Question 6

What principle suggests that traits should be heritable and varied for natural selection to act on it?

Answer 6

Natural selection can only act on heritable traits that differ within a population

Question 7

Which principle suggests that the consideration of beneficial or detrimental trait depends on the environment the population is in? (What is true for one habitat may be false in another habitat)

Answer 7

The traits that nature will select is always a moving target

Question 8

Why should there be variations in traits for natural selection?

Answer 8

Because if all individuals in a population are identical

for a given trait, natural selection would have no option to select from
