Science Explanation and Added Information
Adaptations:
0. (No Pigment - Human): We added in this adaptation to increase the level of survivability of humans. We thought that a reduction in pigment (or increase amount of pheomelanin which causes light skin and hair) would lead to less color in the skin and in the hair (or extreme white hair and skin) which will blend in into the surroundings. With this adaptation, these humans will be less likely to stand out in the snow and they will have and easier time catching their prey. Without this the human would stand out like a paint stain on a white shirt.
The gene that controls pigment is called MC1R. It produces the protein that creates a melanocortin 1 receptor. Melanocortin is located in specialized

By increasing the activeness of those genes the humans can have a higher concentration of hydrochloric acid which means that their stomach is more acidic.
6. (Stomach Lining - Vulture): This adaptation produces more mucus in the stomach lining. This makes it so the stomach is protected from the gastric acid. Without this you would be getting severe ulcers which is very bad for your health. The gene that causes the production of mucus in the stomach is the MUC1 gene which produced a protein called mucin 1. By making the MUC1 gene more active it allows the stomach to have more mucus and effectively protecting it from the acid.
7. (Jaw Muscles - Human): This adaptation allows for stronger muscles in the jaw. We added this so you can effectively chew anything and your jaw won't get tired. Say if you are looking for food and all you see is a carcass, normally you wouldn't be able to eat it because you cannot eat bones. But with strong jaws you will be able to chew anything including bones. Without this it would be hard to get nutrients from animals because all you can eat is the

    3. A mutation in the DNA of rock pocket mouse in location A caused it to have black fur. Because the dark-colored fur was easily visible on the light-colored surface of location A, the dark-colored mice were more easily spotted by predators than the light-colored mice. This phenotype did not become more common since more of the dark-colored mice were not able to survive and reproduce.…

However it is important to note that mutations will also lead to variability which is beneficial to us. Mutations in intergenic DNA affects regulations of protein products which is actually less detrimental than mutations in exons which code for the proteins. 2.…

    3. Explain the concept of a negative feedback mechanism as it relates to gastric acid secretion. The cycle of this negative feedback mechanism starts when food entering the stomach triggers the release of gastrin from the cells of the stomach wall. Gastrin tells the stomach glands to secrete the elements of hydrochloric acid, thus increasing the pH of the environment to 1.5. Once an optimal pH of 1.5 is reached, the cycle reverses.…

    The hominin evolution theory is the idea of Homo sapiens sapiens (AMHs) evolved from a lineage of hominins in Africa. The purpose of the project is to determine the genus and species of seven skulls discovered by Dr. Musoma in Africa, Europe and Asia, approximate the age of each skull, interpret the evolutionary pathway of each species, and provide evidence for and against the “Out of Africa” theory. The purpose of the project with be completed and evidence on the “Out of Africa” theory will be found. Based upon the information left with each of the seven skulls, the remains can be identified with the appropriate genus and species. For all seven skulls, Dr. T. C. Musoma left the cranial capacity, location and the artifacts, if any, found with…

    Bryan Vongkhamdy Articulation of Human Hands in Comparison to Bear Paws Chimpanzees, apes, and gorilla share a very similar anatomy but another mammal also shares a similar anatomy to humans as well. The bear in particular also shares a similar anatomy, specifically the paws of a bear when compared to a human’s hands. Even with similar anatomy, the bear is mostly a quadruped mammal, but is capable of bipedalism, while humans are bipedal mammals. In humans, the hand is meant for a variety of different flexing hand movements allowing for very specific holding and gripping. Meanwhile, in a bear forearm and paw they bring much more strength to carry the massiveness of the body of the bear while walking and running.…

    1. The physical states observed in the species were primarily ancestral characteristics ranging from the more distinct species, gorilla gorilla, to modern human, homo sapiens, they all had molars, flat face with forward facing eyes. Ancestral/primitive characters are the characters that were present in a common ancestor whereas the derived characters are those type of characters that were not present in the common ancestor. One of the observed characteristics for derived characters are large cranium which gradually increased from the opposing small cranium present in the ancestors.…

    Racial Differences

    In terms of genetics, technology has advanced far enough to map out the human genome. As a population, we have found out that there are no ethnic markers that differentiate us from one another, with genetic variation sometimes being greater between two individuals of the same race than two individuals of different races. Even with the knowledge that the human genome insists the lack of a biological race, the persistence of the basal human need to categorize humans into ethnic categories begs the question as to why race still exists. To answer this question, I find it important to understand the basis for racial differences on an anthropological and genetic level and how race began to be a social construct.…

    Stomach Cancer among Asian Americans Although cancer affects all ethnicities, it is the leading cause of death for Asian Americans. Furthermore, it seems that Asian American subgroups each have varying degrees of susceptibility among the many types of cancers. According to Keiro.org (n.d.),” Japanese Americans have a significantly higher rate of stomach cancer than whites in the United States”. The United States has one of the lowest incidence rates of stomach cancer among countries while Japan is among the countries with the highest incidence of stomach cancer. Therefore, genetics may play a big role in stomach cancer among Japanese Americans.…

    Genus Homo Evolution

    Since the emergence of the genus Homo, the hominins went through great patterns of evolution over generations. Through series of adaptations, the genus Homo spread in various geographic locations and eventually emerged as anatomically modern humans. With the allele frequency changes that evolved in the genus Homo, there is key evidence that microevolution led to macroevolution. From speciation to extinction, the modern synthesis helps us explain not only the mechanisms of evolution and the reproductive barriers between species, but also the various social adaptations that changed the hominins over time. From 2mya to ca.…

    This can be seen by looking at the jaw. The movement it makes during chewing, for example, the up and down movement (made by the jaw bone responding to the electrical message sent from the Nervous System) masticates the food so that it is soft enough to be swallowed and travel down the oesophagus to the stomach and then to the small intestine to be broken down and digested so that the body can gain the nutrients and energy it needs from the food products and then excrete the waste products it does not need. This entire digestive process begins with the movement of the jaw bone, which could not be completed without the Musculo-Skeletal system. It is clear that there are numerous functions of the Musculo-Skeletal sytem. It provides form, protection, support, movement and works in harmony with other systems within the body.…
