Question

Organisms with advantageous adaptations are more likely to survive and reproduce than organisms without the advantageous adaptations. This phenomena is known as natural selection.

In order for natural selection to occur
A.) organisms within a population must have some genetic variation.
B.) there must be more male organisms than female organisms.
C.) all of the organisms within a population must be exactly the same.
D.) one population must become extinct so another can be created.

Answer 1

A. organisms within a population must have some genetic variation.

Answer 2

In order for natural selection to occur organisms within a population must have some genetic variation. Natural selection is when species learn to adapt to their environment. They could (1) differential reproduction, that is, not all organisms are able to reproduce to their fullest capacity because nature cannot simply sustain it and (2) acquire genes, that is heredity. Certain characteristics of organisms tend to survive if it continues to strive. If it survives, this trait is passed down to the next generations forgetting the other traits but only the one who could survive the environment. Therefore it is true that natural selection is when ‘organisms inherit advantageous traits, and tend to reproduce more successfully than other organisms’.
