Evolution Of Humans Under The Lactose Intolerance Aspect Of Us As An Organism

Thesis: Humans are designed to drink human milk, not cow’s milk. Humans should really old drink milk during infancy and that’s because all of the hormones in cow’s milk can cause many health issues.

As humans evolve both as a species and a society, new questions will unfold. While at university, I look forward to developing the skills required to answer these questions whilst establishing a career in Biomedicine in which I can continue to learn about the human

I have always found human evolution very fascinating. I think it is incredible how we have evolved from caveman to complex modern-day humans. The fact that such an enormous change did not occur overnight, but through a slow process that took place over hundreds of thousands of years, gives me the urge to continue researching. I am curious about how we have evolved dramatically in terms of appearance, characteristics, lifestyle, and many other aspects. Not only are these adaptations interesting, they are also essential to our entire existence. Without evolution, humans would’ve died out due to the various diseases we are exposed to daily. Evolution is a constant undergoing process as our surroundings continue to change. We must adapt to these changes in order to successfully survive. I want to

Animal meat has all necessary nutrients, especially protein that is necessary for the human body to grow and function properly. Besides, it plays a vital role in brain development. As suggested by Smil (2013), “Killing animals and eating meat have been significant components of human evolution…have inevitably contributed to the evolution of human intelligence…” (p.1). According to the findings of the University of Colorado (2012), anthropologists have excavated a toddler’s “skull fragment” in Tanzania that is the abnormally tiny size of skull, due to a protein deficiency in the diet and led to youth mortality; this condition was very rare in 1.8 million years ago. This indicates that animal meat is a paramount in the human body, without the essential amino acids that exists in animal meats; human evolution cannot happen (p.1).

Lactose Intolerance Lactose intolerance is the inability to digest significant amounts of lactose, the predominant sugar of milk. This inability results from a shortage of the enzyme lactase, which is normally produced by the cells that line the small intestine. Lactase breaks down milk sugar into simpler forms that can then be absorbed into the bloodstream. When there is not enough lactase to digest the amount of lactose consumed, the results, although not usually dangerous, may be very distressing. While not all persons deficient in lactase have symptoms, those who do are considered to be lactose intolerant.

Macroevolution (the change of one species to another through natural selection over a long period of time) is currently taught exclusively in many public high schools as the leading theory for the variety of species on Earth, including human life. Everyone who has sat in a high school biology class has heard that humans have evolved over time from a single cell to more complex organisms such as apes to our current state of humans. There is much controversy on the validity of the macroevolution theory which has numerous evidentiary shortcomings. Unlike microevolution (successive changes within a species due to natural selection) which is easily proven through examining bacteria, macroevolution is a best-guess science. Because macroevolution

According to “Got Lactose?”, cultural behavior affects evolution. In this excerpt, it is shown that cultures that included lactose in their diets, such as European and East African cultures, are lactase persistent in adulthood. Other cultures, such as Asian cultures, that did not include lactose in their diets, did not continue to be lactase persistent in adulthood. This is shown in the example of what happens during a famine. During famine, when milk was a majority source of food, those who could not process lactose died off, leaving those who can process lactose to survive. So now, those there today have the mutation that allows them to process lacto

Human beings are still very much evolving. According to recent studies, genetic changes in women over the years have decreased the age at which they birthed their first child. In one study the age decreased as much as four years from age 26 down to age 22 (Allen 2011). Another concurrent study looked at women’s physical appearance in correlation with the number of children they had. The resulting data revealed that, “stout, slightly plump” women had more children. Researchers found that these characteristics are passed on from mothers to their offspring and so forth (Harrell 2009). Therefore, as these traits are passed from generation to generation, the population grows and these characteristics become more prominent in the population. All of these findings confirm that the evolution of human beings is still very much an ongoing process.

Understanding human evolutions is important for identifying the stages of humanity and for understanding how our societies have developed. When most of us think about human

Enzymes are essential to the proper functioning of the human body. Enzymes are catalysts, which cause reactions to occur. The two primary classes of enzymes for maintaining life functions are digestive and metabolic enzymes. The primary digestive enzymes are classified as proteases, amylases and lipases. These enzymes can help breakdown food molecules. Metabolic enzymes are responsible for the repairing and structuring of every cell. Inadequate production of digestive enzymes can have a negative impact on the breakdown of food into the various nutrients our bodies require.

Abstract evolution has occurred in humans for millions of years; however, in a modern society many scientists and evolutionists are now debating whether or not it is still occurring, and if it follows the same rules. With all of the new technology humans have created, some experts believe that humans have essentially conquered nature, and no further evolutionary changes will occur. Still, others hold opposing views; some experts believe that evolution is still occurring, but modern societal advancements have changed the rules. These experts say that the changes in evolution are a result of recent medical advancements that allow doctors to perpetuate genes that would not have lasted years ago. Additionally, others maintain that evolution is

Although some evidence is indisputable, such as women becoming pregnant, evolutionary psychologists need to update their theories to align with recent findings.

“Although we are all members of a single species, we differ from one another in such visible traits as the color of our skin and the shape of our noses, and in biochemical factors such as our blood types and our susceptibility to certain diseases” (Sheridan College Institute of Technology and Advanced Learning, 2013, p. 34). To understand human physical development and evolution one has to understand biological anthropology as the focus on humans as biological organisms. Biological anthropologist conduct research, and form techniques of modern molecular biology to learn about human variation and how it relates to different environment humans lived in as well as their conditions.

The theories of human evolution may always cause a heated dispute. Each theory presents its own evidence proving

Humans have existed on Earth for approximately 3.4 million years. The oldest known human ancestor is "Lucy," an Australopithecus. Over this extensive period of time, humans have evolved significantly. Homo Sapiens have grown from 3 to almost 6 feet (average), lost most of the body hair, became leaner and adapted to walking. Humans have come a long way, from Australopithecus to Homo sapiens, from living in trees to living in cities. Slowly, through hundreds of thousands of years, we mutated over and over again, natural selection ensuring that no destructive mutations continue. From the slow evolution, four distinctive species emerged and died out, each giving way to its ' descendant: Homo Habilis, Homo Erectus, Homo Sapiens Neanderthalesis, and Homo sapiens Sapiens.
