yes.
All species have genetic variation. ;D
It's about Charles Darwin's journey and discoveries on The Beagle. Also, Darwin believed all species had the same ancestor and evolved from them. There are 2 purposes: to 1. To explaining what natural selection is and how it could produce new species and2. Respond to objections that those who do not agree with natural selection might have
We call this speciation, and is largely driven by evolution and natural selection.
Charles Darwin is associated with the theory of evolution by natural selection, which explains how species evolve and adapt to their environments over time through the process of natural selection. He is best known for his work on the origin of species and the idea that all living organisms are descended from a common ancestor.
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.
The book "On the Origin of Species by Means of Natural Selection" was written by Charles Darwin.

how natural selection help some species to survive and few got extinct
It is not a matter of agreement, it is a matter of accepting the overwhelming evidences in support of the theory of evolution by natural selection.
Natural selection usually causes a species to change gradually
Variations in a species are needed for natural selection to occur because they provide the raw material for evolutionary change. Without variation, there would be no differences for natural selection to act upon, and individuals within a species would be identical. Variations allow some individuals to be better adapted to their environment, giving them a higher chance of survival and reproduction, thus driving the process of natural selection.
