Evolution Of Human Species

The human race is one of the most complicated species regarding the idea of evolution. For the past thousands of years, humans have evolved drastically. From early humans to present day, humans have developed mutations as a result of natural selection and have become the most intelligent species on this planet. But are humans still evolving or has the development of technologies halted the progression of mankind? The human species continues to evolve; research shows that the human species is evolving at about the same rate as other animals, the number of genetic mutations for diseases in DNA are decreasing, and the adaptation of lactase supports the evolution of humans.

Human evolution has proven that it is no slower than the rate of other

Lactase persistence has become more apparent in a larger number of the population and is even more widespread than what scientists originally predicted, (Krüttli, 2014). In the Middle Ages many Europeans began to develop a mutation in their DNA that allowed them to digest a sugar in milk called lactose. The mutation allowed people to create an enzyme called lactase which is able to break down the lactose, as a result of the agriculture and animals living on farms in Europe. Because of the genetic mutation for lactase many more people are becoming lactase-persistent. The University of Zurich “conducted [research] on human remains from medieval Hungary, which exhibited a lactase persistence rate of 35 percent compared to 61 percent in the country today,” (Krüttli, 2014). The evidence of an even higher projection of those with lactase persistence reveals that evolution in humans is still happening. Many more people are developing and inheriting lactase persistence through natural selection. Others may argue that the evolution for the lactase mutation ended with the evolution of modern humans. The mutated gene had evolved in Europe during the Middle Ages as a result of building up a persistence to milk from their farm cows and is irrelevant to human evolution in the current day. While this is true that humans did first develop the gene in the Middle Ages, the evolution of lactase is still an important piece which is is present in current human evolution. An even higher amount of humans are inheriting the gene for lactase persistence and the numbers continue to rise supporting in the idea that humans are still
