Positive And Negative Effects Of The Neolithic Revolution

In this essay I will discuss the adaptations on human evolution, this includes skin color, disease, Lactase Persistence, and the negative effects of the Neolithic Revolution. I will focus mostly on the diseased portion the most because this plays a vital role in natural selection. Natural selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring (dictionary.com). Without disease natural selection would play less of a part in how species evolve. Skin color is important in surviving when most feel like it is because we are different, when in reality we are 99.9 percent identical (Human family tree). I will compare the negative and positive effects of the Neolithic revolution all while explaining the lactase persistence and how it differs from lactose intolerance.
Disease
Microbes are the germs in which live off our bodies and make humans sick, whether to the point where we die or pass the germ to someone else. These microbes help with natural selection, and the process at which we evolve. Most often than not the disease is spread by contaminated water, not cooking the meat all the way or being bitten by an animal that has the
Humans began to cultivate crops and domesticate certain animals. This is the time when men and women began to separate into hunting and gathering, although this occurred men still controlled their society. There was positive effects of the Neolithic revolution in the use of agriculture allowed humans to develop permanent settlements, social classes, and new technologies. Even if there were positive effects there were negatives to this revolution examples of these were warfare, crop failure, and disease. By domesticating animals it caused disease, also their crops failed because of rainfall or they did not have the necessary tools to
