Are humans affected by natural selection?

Answers

Yes! A recent example could be babies that do not survive child birth for a certain reason, are obviously unable to pass on whatever caused them to die in the first place.
Also, once humans started to domesticate cows and drink their milk (I'm not sure why humans drink a cow's milk) their bodies evolved to continue making the enzyme to digest milk even after they were weaned off their mothers milk. Many people of Asian descend do not have this enzyme, since their culture did/does not raise as much dairy product.

What is mitosis?

In the study of cell biology, the phase of the cell cycle known as mitosis is the stage at which replicated chromosomes are partitioned into two new nuclei. Mitosis is a method of cell division that results in the production of cells that are genetically similar and in which the total number of chromosomes is preserved. Since this occurs during mitosis, the process is often referred to as equational division.

Conventionally, the process of mitosis is broken down into five stages that are referred to as prophase, prometaphase, metaphase, anaphase, and telophase.
