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
Lab 105 Human Species Lab Report
1592 Words | 7 PagesAnth. 105 Human Species – Lab 3 Report Sirin Gul November 11, 2017 Introduction In Lab 3, we examined the relationships between diet quality, tooth shape and daily travel distance. Evolution has changed how humans and other primates live and survived according to their environment. They are relatively related/similar to each other when it comes to fossil hominins, humans and other primates.
Helen Pilcher Primate Evolution
681 Words | 3 PagesThe article I have chosen was written by Helen Pilcher and is about evolution of creatures, especially for primates. However, until now, what do our very first primates were like still remain mysterious as we do not have sufficient information and evidences which are 60 million years ago. Yet, we still cannot deny that evolution occurs in creatures. No matter for humans, animals or plants, all of them will make changes because of their living habits and environment in order to survive. In this article, the author explains everything clearly about the primate evolution was taken around million years ago and ancestors are a small and nocturnal creature.
Lab 105 Human Species Essay
780 Words | 4 PagesThis all depends on body mass. Humans have the largest body mass compared to primates and apes. Since they have the largest body mass, they also have the largest brains, the longest life span, reproduce at a much later age and have a large EQ. In this project, we investigated how and when the human-like pattern of large brains, long growth periods, and maximum lifespans evolved by examining and estimating these traits in fossil hominins.
Survival Of The Sickest Chapter 1 Summary
1455 Words | 6 PagesDr. Moalem’s unique view on disease and humanity’s complex relationship with it inspired many questions in the mind of the reader. He theorizes that diseases passed on genetically remained in the gene pool because they may have provided advantages to our ancestors, and this theory casts a new light and creates a new perspective on such diseases. The diseases discussed in the book, such as hemochromatosis, diabetes, and hypercholesterolemia, would ordinarily be considered harmful. However, the author explains that under different circumstance, these illnesses might have been viewed as beneficial instead, and that these benefits are worth
Rhetorical Analysis Of Brett Favre Advertising
2237 Words | 9 PagesWithout question whole cow’s milk is high in saturated fat and cholesterol, both of which should be avoided. In addition, there has been growing concern that three health issues associated with milk consumption have gone ignored and demand immediate attention: lactose intolerance, type-1 diabetes mellitus, and prostate cancer. A study in 2002 examined “the links between milk consumption and both type 1 diabetes mellitus, and lactose intolerance. These 2 topics...have received major and extended coverage in the media and have raised broad concerns about the safety of milk for children” (Goldberg, Folta, Must). In this study were revealed results of a Finnish study of cow’s milk consumption where the authors stated “...these data support the hypothesis that there may be a subset of at-risk children for whom cow's milk consumption promotes the development of type 1 diabetes” (828).
Nonhuman Primate Evolution
294 Words | 2 PagesClimate change influenced nonhuman primate evolution in a variety of ways. Around 55 mya, a serious period of global warming occurred just as euprimates were beginning to appear. Our book discusses how this rapid temperature increase created tropical weather conditions all across the globe. As a result, new habits were created and there was "an adaptive radiation of modern-appearing primates, the euprimates" (Larsen 260). In other words, the high global temperatures paired with the humidity let to the spread of tropical forests.
Nonhuman Primate Evolution
310 Words | 2 PagesClimate change influenced nonhuman primate evolution by forcing the evolution of species and creating new environments that allowed for primates to live. "A rapid temperature increase around 55 mya ... led to an expansion of evergreen tropical forests, the environment that made possible many mammalian groups, including primates." (pg. 260). As rapid temperature increase created new environments a rapid cooling in the beginning of the Oligocene limited the range of habitats greatly. Due to this reduction a majority of the primates during this time lived around the fayum region in northeast Africa.
Nonhuman Primate Evolution
195 Words | 1 Pagesclimate change influenced nonhuman primate evolution because with the changes, nonhuman primates were forced to evolve in order to survive. As the climate change progressed and several species started to die out, nonhuman primates evolved through time and thus they were able to survive and climate change that occurred and were able to evolve into creatures that we see during present times. The theories of early primate evolution appeared about 60 million years ago after most of the early living species had already become extinct. New discoveries have supported one theory over another as more research is done.
The Planet Of The Apes Analysis
675 Words | 3 PagesApe’s Only True State Innovations from the intelligence of man has been the key factor to change in our culture. It all started with the human race discovering fire a long time ago in the Stone Age. Now we stand in the 21st century, and we have made far strides consisting of cell phones, cars, flight, space travel, robots, etc. The human race started with something so little and they turned it into something unimaginable. Just like Pierre Boulle 's novel, “The Planet of the Apes” he portrays that innovation and the advancements of technology only comes from the human species.
Primate Evolution Hypothesis
477 Words | 2 PagesClimate change had a heavy influence on nonhuman primate evolution. Modern primates live in areas with a warmer climate where forests tend grow thickly, mainly in the southern hemisphere. However primates used to have a much more diverse habitat, living in more areas of the world than they do today. This is directly a result of climate change which has forced primates to change habitats. Climate change also occurred multiple times between the origins of early primates and modern day primates however.
Primates And Personhood Summary
355 Words | 2 PagesThe article, “Of Primates and Personhood: Will According Rights and “Dignity” to Nonhuman Organisms Halt Research?” by Ed Yong is trying to convince the reader to see a different side to primates. The Great Ape Project set legal rights for chimpanzees, gorillas, bonobos, and orangutan. United Kingdom and New Zealand protect great apes from experimentation. For the Great Ape Project they are basically setting laws and higher standards for primates to me experimented on or held captive.
Paleo Diet Essay
516 Words | 3 PagesThe caveman only ate non-toxin edible foods. In the Paleolithic period dairy products were not consume because animals had not at all been domesticated. Therefore, milk was not at all consumed. The Paleo Diet includes: lean meat, fish, poultry, fresh vegetables, fresh fruit, nuts and seeds. Excluded from the diet are grains, potatoes, legumes, dairy produces, salt, refined sugar and processed foods.
Similarities Between Modern Man And Neanderthals
1649 Words | 7 PagesDeborah Swarthout Modern Man and Neanderthals WCCCD-Fall 2017 Modern Man and Neanderthals: Where did they go? It has long been thought that modern man evolved from the Neanderthals. Although we have many similarities, the most recent studies suggest that modern man actually co-existed alongside the Neanderthals and interbred with them to create the modern man we know today. Neanderthals or Neandertals (Homo Neanderthalensis) are considered to be our closest extinct human relatives.
Are Humans Still Evolving Essay
609 Words | 3 PagesEvolution is the development and change within heritable traits of different populations over generations. Over the years, humans have begun to invent things and change around their environment (the world) to suit their needs. With this is mind, we humans have not been paying attention to how these changes are affecting our evolution as a species. We are cheating natural selection with the design of medicines and medical procedures that allow us to live longer.
Human Evolution Went Too Far
307 Words | 2 PagesThe evolution of the human race went too far: they were blinded by their greed and ended up consumed by it. The technological evolution got way too far and they got to a point in which the society depended on the machines to keep on living, the Frame was the main computer or system, it could control everything, from machines and computers to lighting systems. The group that is shown in the story was trying to avoid human extinction by fleeing the planet and going somewhere else. They were part of the government, what means that what was happening was their fault and they knew it.
