The Academy of Science: Natural Selection
Anthropologists are continuously exploring the far corners of the world in search of answers to how everything came to be and the process by which we as humans appeared on this planet. This is a difficult task and therefore, there are many branches of anthropology which strive to discern the pieces of the puzzle from different perspectives and approaches. Through the implementation of the scientific method, anthropologists have tested numerous hypotheses to create theories like the Theory of Evolution. First documented by Darwin, natural selection, the process by which a more fit individual survives and passes on their adaptive traits, has been discovered to play a crucial role in the evolution of

Down on the ground there is an immense amount of biodiversity, however animals who call this layer of the rainforest their home, must adapt to living on the ground and through selective pressures develop features that protect them. For example, at the exhibit there were little orange frogs called Golden Mantella, who at first sight stood out in contrast to the brown and green environment of the forest floor. However, through further reading it seems these small creatures have been selected for orange skin because it advertises to predators that they taste bad, and therefore protects them and guarantees that their genes will be passed …show more content…
In this environment it is vital for organisms to be able to navigate across the branches and vines with agility. It is here where the arboreal Howler Monkeys spend a lot of their time. These primates are recognizable from a distance by their loud cries due to their large genetically inherited hyoid bone (hence the name “howler”) and are among the largest of the New World Monkeys. They move across the rainforest quadrupedally on the tops of branches, grasping them with two hands or with one hand and their prehensile tail which they also use to pick fruits and nuts with. Because these primates have adapted to eating leaves they possess two large sections of hindgut, the caecum and the colon (Natural History Collection: New World Monkeys). A fascinating characteristic pertaining to the howler monkey is in fact their tail, which can fully wrap around objects. Not only that but their tails also have tactile pads, like those found on the hands and feet of humans and apes, which gives them the advantage of a fifth limb. This selected trait has guaranteed their success living in the rainforest canopies because they can move agilely and escape predators (Gron, Primate
“The Tall and the Short of It” by Barry Bogin in 1998 show the prime example for applying anthropological theories in order to understand the evolution of the human process. This article show how anthropology is used to reaffirm and or disapproves the scientific theories about human development. Bogin shows through Biology Anthropology by explaining the characteristics of genetic of the mother along with the environment can change over time. In “The Tall and the short of It” Bogin show how the different concepts of anthropology (Biological anthropology) is used to show how the external environment along with the internal environment process help shapes human development.
Natural selection is the process in which heritable traits that make it more likely for organisms to survive and successfully reproduce become more common in a population over successive generations. Each of us individuals is specifically shaped and formed by our own genetic pattern. We inherit this pattern half from are mother and half from are father. The cause of this is the proximate cause that led it’s phenotype to ultimate causes. Much of we know today about evolution derives from the late great pioneer, Charles Darwin. Charles Darwin was an english naturalist that even from an early age was very interested in outdoor pursuits. Early in his prep career his father tried sending him to the University of Edinburg to pursue his medical

Human evolution: the study of how and why our human ancestors changed over millions of years.
At the age of 11, my family and I visited The Museum of Natural History in New
Natural selection is considered one of the most important processes for a variety of species and the environment which allows the fittest organisms to produce offspring. To prevent a species from extinction, it is necessary for them to adapt to the surrounding environment. The species which have the ability to adapt to new surroundings will be able to pass their genes through reproduction. Within the process of natural selection, it is possible for the original genetic make-up of a species to become altered. The team will report on the different processes of basic mechanisms of evolution, how natural selection results in biodiversity and why biodiversity is important to continued evolution. The sources of genetic
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
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
GMO stands for Genetically Modified Organism, which is the process of extracting genes from one species into another unrelated species. The process of transferring DNA from two distinct species is through genetic engineering. This displays the new traits of the first donor, which will be part of the genetic make up of the recipient organism. GMO is different from cross breeding or hybridization. Scientists developed GM plants by introducing genes that kill insects and protect crops against viruses. Many of these GM plants require less water so that they are able to grow in areas where water is scarce. The benefit of GMOs help crops grows and ripens faster so that farmers are able to grow more crops throughout the year. On the other hand, GMOs may be harmful to humans if they are not washed and cleaned properly before eating. GMOs include high risk of allergens, toxins, and other unknown side effects that are harmful.
Evolutionary theory is an important part of physical anthropology as it helps the researchers to have a solid
Anthropologists and other scientist use different types of method to study the evolution of human behavior, depending on their specific interest and expertise. First approach is the Paleontological Reconstruction; these reconstructions were constructed on the anatomy of existent of hominins and the archaeological remains, which they were connected. They were also found associated among behavior, anatomy, and ecology discovered in non-human primate species and in modern humans. Next is the Biological approach, which is understandable that human cultural behavior has affected human evolution. Biological and evolutionary heritage may have developed several methods behavior that has been discovered by others. Third approach is the Evolutionary Psychology, which emphasize on understanding the behaviors or cognitive modules adaptations. Evolutionary psychologist is convinced that our evolved behavior may indicate or should be explained in terms of theoretical environment of evolutionary adaptedness. Lastly, is the Human Evolutionary Ecology, which emphasize more on psychological experiments and surveys of individuals living in developed countries, also on the ecological factors that impact reproduction success in the few remaining hunter gathered
“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
Evolution refers to "change over time". In terms of physical anthropology, evolution is changes over time in living organisms. This means that living things have passed their traits from one generation to the next. There are very little changes that occur with each generation, but over time these changes accumulate in each living organism. It is believed that all life on Earth has common ancestry that lived more than 3.5 billions of years ago (Park, 2008).
