Organisms are affected by Natural Selection because Inherited characteristics affected the likelihood of an organism's survival and reproduction.
natural selection is basiclly only the strong survive which means it effects the weak by killing them but bernifits the strong
Through ongoing natural selection a population adapts to its enviroment
Natural selection is the process which determines the shark's evolution. It is humankind that is threatening the sharks' survival.
Populations evolve, but individuals are selected. Natural selection affects individual organisms.

Evolution by natural selection is currently the only viable theory explaining the diversity of life. However, the mechanism of natural selection is not the only mechanism to affect evolution. There are phenomena such as genetic drift, biased gene conversion, intragenomic conflict, and so on, that aren't exactly the same as natural selection (although they are all intertwined and all affect one another), but do affect the direction of evolution.
Humans directly affect artificial selection. They do this by selecting the specific traits that they prefer which they cannot don in a natural selection.

How does natural selection affect undesirable traits?
