A significant biological adaptation of hominoids was the ability to walk “upright on both hind legs”, or bipedalism. Bipedalism marked a substantial moment in time as it was the first biological chan...

...ison, much of the modern human population of today possess traces of Neandertal DNA amongst their genetic makeup. This indicates that Homo sapiens and Neandertals were close enough genetically to allow for interbreeding during the overlapping 10,000 years or so they were suspected to have existed at the same time.
In regards to the history of the various human ancestors, evolutionary ties to culture and biological adaptations are evident, with an emphasis on culture. Culture specifically has been implicated in the development of biological adaptations of brain function, leading to further cultural development as language began to come in to existence. The feedback loop between specific cultural actions and the development of language were explored in the Nova video, complementing the idea that culture plays an important role in evolution when it comes to humans.

- Each module and chapter in this course is used to open the eyes and give informative information in regards to the Evolutionary Theory, and also to explain why evolution is true. It also takes you through the process in which species and individual organisms have evolved and developed in to new life forms to create the world we live in today through the form of fossils, homology, selections, micro and macroevolution. As I went module by module and through each chapter my initial thoughts regarding evolution began to become questionable in my eyes.... [tags: Evolution, Life, Organism, DNA]

- ... (Westrup, 2002) These multiple similarities of humans with aquatic organism and the environmental situation of the time, greatly suggest and helps proves that AAT best fits the explanations of the man/ape primate evolutionary split. The Aquatic Ape Theory explains the start of human evolution on the bases of basic evolutionary terms established by Charles Darwin. As explained earlier, the theory states that humans traveled from the wooded area toward water. In doing this, humans adapted to the new aquatic environment, dealing with survival of the fittest and geographic isolation which caused speciation.... [tags: human evolution, savannah theory]

- The definition of the term ‘evolution’ summarized into one sentence refers to the changes in genetic traits or mutation between several generations. This change in genetic traits usually occurs during the breeding process, where the genes are copied passed on to the offspring. As a result the mutation, the genetic variation would occur between individuals. The new character/s could transfer within the specie due to the horizontal transfer of gene and migration. As the genetic variation/s become common between the specie through ‘natural selection’ or random genetic drift effect, evolution occurred to this specie....

- The question of how long modern humans have been on Earth is a riddle that scientists have been trying to answer for centuries. One of the most popular theories to try and answer this question is the theory of evolution, which proposes that humans in their modern form (Homo sapiens) have only been around for about 100,000 years. Before then, there were no modern humans, only their predecessors, the Homo heidelbergensis, Homo antecessor, etc., descendants of the apes. This theory has become the basis of science curriculum throughout our public schools and in many states teachers are prohibited to present any material opposing evolution, thus giving students the impression that evolution is a...

- Savanna Theory Versus Aquatic Ape Theory of Human Evolution The evolution of man is constantly in question. While we are reasonably sure that modern humans and primates are both related to the same common ancestor, there is constant debate over what initially caused the two species to split into early hominids and apes. According to some, our longest and most popular theory on the division of man and ape is profoundly wrong. However, those same individuals usually offer an equally controversial theory as a substitute, one that is almost impossible to scientifically test or prove....

- Darwin. Just the mention of his name can peak a person’s interest and result in a controversial and personal opinion of Darwin’s theory concerning evolution. His theories came at a time when a majority of the world felt comforted by the belief that humanity came from a supernatural and faith-required beginning. Evolution has and undoubtedly will continue be a topic of controversy. The reason for that is because religion still has a huge element in the lives of people. Despite the claims of fallacy towards Darwin’s theory of evolution and the unwillingness of acceptance from the public that was exposed to his theories, Darwin nevertheless gave his theory a backbone and came out on top, as eve...

- Evolution theory led to great advances in the understanding of human behaviour and has had considerable impact on the study of religion. This essay will first show its importance in new-atheist discourses to reshape religion as handling ontological claims about the world, which can then be investigated and dismissed on the basis of scientific evidence. Then it will discuss how evolution theory has also been used to explain the emergence of the religious phenomenon and its diffusion, as an adaptive trait favouring cooperation or as a parasite detrimental to human kind....

- Leslie Stevenson and David L. Haberman’s Ten Theories of Human Nature provides an insightful introduction to important philosophical, religious and scientific theories, or ideologies, and their depiction of human nature. The book is meant to provide the reader with a guidance for how we should live, based on ten different theories. The book consisted of ten chapters, each examining a particular theory, presented in a chronological order. Throughout each chapter, historical context was first provided to the reader, followed by a definition of essential terms, a diagnosis of the ways the theory depicts human nature, then a prescription for how one ought to live, and ending with later dev...

- The theory of human evolution, contrary to creationism, which is the belief that “all present life-forms were spontaneously created at one point in time” is a scientific theory which proposes that the human species branched off from apes millions of years ago. In its simplest definition, evolution is the idea that changes within a species occur progressively over time, thus all lifeforms on the planet today have descended from earlier ones that existed long ago. The man responsible for popularizing the theory of evolution was English biologist Charles Darwin, who devoted his life to systematically finding evidence to support the concept....

- Biological Anthropology Question 1: Evolution Versus Creationism Creation or evolution. Such a question holds significant importance to the human race, raising further questions such as where did we come from, how did we get here, and more importantly where are we, the human race, going and where will we end up. Creationism, as cited from Oxford Dictionary, is “The belief that the universe and living organisms originate from specific acts of divine creation, as in the biblical account, rather than by natural processes such as evolution,” answers in its very definition one of humanity 's great questions referring to our origin....
