A; random events. It is widely known that genetic change is a random event. If a random genetic alteration exibits a favorable phenotype, then the new phenotype will have a more favorable chance of passing on the new genetic information, thus carrying onward the new gene.

the fixity of species.
why?
cuz we live in a society today where we are so fixated on youthfulness and beauty. we go through many obstacles to look beautiful and attractive. many people get plastic surgery for breast implants, liposuction, botox, etc etc. obesity is frowned upon in today's society.
this is the most important force in shaping evolution because within time [in the next million years] us humans will eventually look a little different. our gene pool will change. humans will have nice glossy hairless skin. perky breasts, and nice lean tall bodies.
