Natural selection is the process which determines the shark's evolution. It is humankind that is threatening the sharks' survival.
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.
