The most important experience of Darwin's life was his trip aboard HMS Beagle as a naturalist. The Beagle left England in 1831, and it returned in 1836. The overall purpose of the voyage was to map uncharted areas of the South American coastline. And then, he wrote the theory of Natural Selection:
ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ One of the prime motives for all species is to reproduce and survive, passing on the genetic information of the species from generation to generation. When species do this they tend to produce more offspring than the environment can support.
ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ The lack of resources to nourish these individuals places pressure on the size of the species population, and the lack of resources means increased competition and as a consequence, some organisms will not survive.
ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ The organisms that die as a consequence of this competition were not totally random; Darwin found that those organisms more suited to their environment were more likely to survive.
ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ This resulted in the well-known phrase survival of the fittest, where the organisms most suited to their environment had more chance of survival if the species falls upon hard times.
ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ ÃÂÃ Those organisms that is better suited to their environment exhibit desirable characteristics, which is a consequence of their genome being more suitable to begin with.
In my opinion, this theory is a great invent that change the future of science and also the society from his time to today, and it still affects the science world in the future. Darwin's natural selection is an axiom in science, especially in biology. Nowadays, many scientists still use his theory in science research, like the scientists who find out how to destroy the HIV. However, I don't agree a piece of this theory, because I don't think human is a part of the organisms in his theory. Human...
