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.
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.
how natural selection help some species to survive and few got extinct
Notincluding human intervention. Natural selection.
The influence of providing an explanatory mechanism for what was obvious to Darwin; species arose and species went extinct.
when there are no living members of a species the species is said to be "extinct".
Adaptation (I'm studying the same thing ;)
Go extinct.
It becomes extinct.
1) a natural catastrophe (eg an asteroid impact) 2) evolutionary changes.
Sometimes this is called natural selection.
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.
When a new species arises from natural selection, it is called speciation. This process occurs when a population becomes reproductively isolated from another population, leading to the formation of distinct species over time.
