Her boyfriend, Zach, was inspecting her skin very carefully. “Look,” he answered her, his voice taking on a more serious tone. “Today a woman walked into the clinic for her annual physical. Everything about her seemed fine. She leads a balanced lifestyle, she eats well, she exercises:

the results can be interesting from extinction to significant changes within a species. Human beings are no exception to biological evolution. Like other organisms around the world, humans have significantly changed overtime and have developed all sorts of diverse characteristics. One noticeable characteristic of human beings is the variation of skin

There are so many things that define a human being: name, hair color, eye color, skin color. However, memory plays just as big of a role in giving a person his or her identity. Memory tells the likes and dislikes, friends and foes, and pleasant and traumatic experiences of a person. Sometimes, though, the memory can be misleading since the brain is able to repress memories of traumatic experiences. In the 1990s, there was a surge in the amount of curiosity scientists had about repressed memories

Skin color is a real life example of evolution in humans.In both the Skin Deep and the TED talk, they discuss and take a deeper look into the differences in skin color. In both the article and the video they hypothesized that our skin has developed over time to be dark enough to prevent the damaging sunlight that has been harming our skin and the nutrient folate that it carries. However, at the same time out skin is light enough to receive vitamin D. Scientists have studied this topic extensively

significant role in human evolution. In this paper I will discuss the importance of melanin in its role in the human biological system and how it relates to the natural selection of suitable human life according to geography and environment. Human pigmentation is influenced by hemoglobins within blood vessels in the skin, carotene and melanins. Melanin, the basis of pigmentation, can be found in the forms of eumelanin and phaeomelanin. Eumelanin is the brown-black pigment located in the skin, hair, and

the article Skin Deep written by Nina Jablonski and George Chaplin, they discuss and look deeper into the diverse differences in skin color. Our skin color has developed over the years to be dark enough to prevent the damaging sunlight that has been harming our skin and the nutrient folate that it carries. At the same time out skin is light enough to receive vitamin D. Anthropologists and geographers have studied and overtime come to the conclusion that distribution of skin color is not random

In the article, Skin Deep by Nina G. Jablonski and George Chaplan, the authors are attempting to explain how the human skin color has evolved to be dark enough to prevent sunlight from destroying folate but light enough to enhance the production of Vitamin D. The changes in skin pigmentation have evolved since the age of Lucy, who is a skeleton of the ancient humans that is about 3.2 million old. Lucy is being used to determine where and why our ancestors began changing in skin pigmentation. The

most of that and touched on the main points. The concept of race is a human construction. Painter called it an idea. The main point of the video is the concept of “whiteness”, and how it has evolved over time. She begins by discussing the idea of what it meant to be considered a white person in ancient Rome. In ancient times, people concentrated on cultural differences rather than physical differences, such as skin color. She then goes on to discuss the concept of whiteness in America. The term

It assists in providing for basic human needs such as food, shelter, and medicine. It composes ecosystems that maintain oxygen in the air, enrich the soil, purify the water, protect against flood and
