How does artificial selection depend on natural selection?

Answer 1

Artificial and natural selection are two matters which are very different however can be easily confused.

Natural selection describes the process of evolution. Natural selection occurs when there are two animals of the same species who have slightly different features. For example, thousands of year ago, giraffe's had short necks. However one happened out of chance to be born with a long neck. The giraffe could then reach the leaves and eat what the short-necks could not. It was easier for this giraffe to survive and in times of famine where the other giraffe died of starvation, the long-neck did not. He was best adapted to his environment, and so he survived longer, and could breed. His children carried his long neck gene and so survived more efficiently than short necks. As a result the long-neck giraffe thrived and the population grew, while the short necks died out. Soon, all giraffes had long necks due to their one common ancestor.

So:

-Mutated baby with long neck born

-Child better adapted

-Survived

-Bred and passed on genes

-These survived and bred

-Population of long necks grew

-Short necks died out due to starvation

Due to natural selection, which is the process of these adaptions changing, all giraffe's now have long necks.

Artificial selection differs as humans intentional choose mutated offspring and breed them, to create certain characteristics. There is no difference between the processes however evidently survival is not key as the humans look after the animals. The only difference is the key term 'artificial' meaning that there is human interference.

Answer 3

They are both basically the similar, except artificial selection involves human intervention while natural selection is, as the name implies, natural.

Nature selects only those organisms with favorable traits that help them survive and are likely to reproduce and pass these traits onto their offspring , so it is called natural selection.

When human beings select an organism to produce next generation it is called Artificial selection .

Perhaps for coat color or height.

Answer 4

Artificial selection is when humans choose which individual organisms breed with each other.

Natural selection can be interpreted two ways: 1) Organisms breed without human interference. 2) It is described as "survival of the fittest," meaning the organism best suited to its environment will be the organism that survives and reproduces. For example, Arctic foxes can survive in extreme conditions due to their adaptations, where other foxes will not survive because they can't handle such harsh climates.

Answer 5

In artificial selection, nature provided the variation,and humans selected those variations that they found useful.

Answer 6

Mostly natural selection depends on the environment

Answer 7

In artificial selection, nature provided the variation, and humans selected those variations that they found useful.

Answer 8

It does not, it is the process involved in selective breeding which is nothing to do with evolution.
