how natural selection help some species to survive and few got extinct
According to science, natural selection chooses the best features for the best survival. When those processes do not occur for some reason, the species does not survive.
Natural selection helps a few species survive by favoring those with advantageous traits that increase their likelihood of survival and reproduction in their environment. Over time, these advantageous traits are passed down to future generations, leading to the continuation of those species while others may become extinct.
Natural selection occurs when a certain environment favors a particular characteristic or trait over another. With this being said, when a species becomes extinct, this means that that species' particular set of characteristics or traits was not the most favorable for them to survive in that certain environment.
Charles Darwin believed that animals become extinct due to a combination of factors such as changing environments, competition with other species, and inability to adapt to new conditions. According to his theory of natural selection, species that cannot survive in their changing habitats will eventually become extinct.
Natural variation in artificial selection is used because humans choose from among the naturally occurring variation s in species. Natural selection is related to species fitness because Darwin called natural selection survival of the fittest because those that could survive would carry their species on there for being the naturally selected.

Natural selection may ultimately be his downfall.
Extinction is part of the Theory of Evolution. This goes along with natural selection and survival of the fittest. Organisms that go extinct do so because they are no longer able to survive in the habitat.
The result of natural selection is that those individuals whose characteristics(health, strength, camouflage, skills etc) made them more suited to survive would indeed be the ones who survived at least long enough to successfully breed, and passed on their characteristics to their offspring.
Natural selection explains the process of evolution: evolution by natural selection. It basically means that species with the highest fitness (survival rate) will live, and be selected by nature for the characteristics they possess that make them more apt to survive. Because of natural selection, evolution occurs.
Charles Darwin proposed the theory of evolution by natural selection in his book "On the Origin of Species" published in 1859. It states that species evolve over time through the process of natural selection, where individuals with advantageous traits are more likely to survive and reproduce.
Darwin's theory of natural selection emphasizes that individuals within a species vary in traits, and those with advantageous traits are more likely to survive, reproduce, and pass on those traits to their offspring. Over time, this process leads to the adaptation of a species to its environment.
