Two components: Natural Selection / Struggle for existence 
2. It is mandatory to struggle for the sake of the world 
3.  Natural disasters, epidemics, and shifts in climate.
4. Singing birds who fight for the life
5.  “Dependence of one being on another"
6. The goal is - seed dissemination/ leave more advanced progeny
7. Great number in variation leads to better adaptation (The beak of a woodpecker )
8. Economist Thomas Malthus (only successive generation can continue the progeny on the constant basis)
9.Competition for existence between members of the same species 
10. Concepts of competition and cooperation

Example; domesticated animals, pigeons.
2. Reproductive system of animals depends from environment.
3.The ancient man was purposefully engaged in selection. He left the strongest and healthiest to mate.

Distinguish between conscious and unconscious artificial selection.
2)Conscious - is carried out in accordance with the goal set by the breeder. 
3)Unconscious - when a person does not set goals for himself, but simply eliminates less valuable individuals and leaves the best for the tribe.

I want to read this chapter because,  it is interesting for me to know how humans and  animals naturally behave and react, before they come to learn it.

Chapter 3 Struggle for existence 
In nature it has to be the struggle for existence between every is because it is immeasurably superior feeble efforts by which can make strong/vigorously being can come up. All organic beings exposed to severe competition. The natural selection depends  the existence of some incipient species with what there will be place for existence only for vigorously ones. Superabundance of some species in several places lead to the disappearance of some other organic beings. But in this case it (superabundance of some species) means for one of the organic being's seeds assimilated to this particular place well. 
A Struggle for existence follows from high ratio of organic beings tend to increase. And it should be happen, each organic being during its lifetime should produce seeds and eggs then they should have a struggle for life/existence. So if there is an apparence of superabundance species  by human selection then any country can't hold it on. So thus the value of natural selection is so high for the sake of a normal well constructed life for every being. 
For the more understanding of the "struggle for existence" we can take look a life time of animals. A most slow-breeding animal elephants and if they breeding in every 25 years and at the end of 5th century they would be alive 15 million of elephants descendents from the first pair. 
If there is artificial selection of one specie in different countries or places but only in one country it's offsprings enabled to breed all because they had good conditions for existence in their particular case, I mean every specie is unique and almost every specie requires a special condition and sometimes place is very suitable for some organic beings and sonetimes not. 
Another thing that is also main is the one specie can be favoured by landscape. All we can do, is to keep steady in mind that each organic being is striving to increase at a geometrical ratio. During each season or at intervals has to struggle for life and suffer great destruction. That the vigorous the healthy the happy survive and multiply.

Darwin called natural selection "This preservation of favourable variations and the rejection of injurious variation". Saying it he ment that the any changes that happen may be rigidly destroyed.
2. Darwin suggested that species can change over time, that new species are descended from pre-existing species, and that all species have a common ancestor.
3. Since resources are inherently limited, organisms with hereditary traits that promote survival and reproduction will tend to produce more offspring than their peers, with the result that the frequency of these traits increases from generation to generation.
4. Natural selection forces populations to adapt over time or become more and more adapted to their environment. Natural selection depends on the environment.
