The Biological Topics Of Human Evolution And Natural Selection

The beginning of human history, is no longer a gray area on the behalf of historians, scientist and perhaps geologist. Many specialized in their respectful field. Move toward together to get a world view of human life. History is a word that is always driven out, to look back at a period of time and one might compare the pervious time to the present. It’s vital for us mortal to understand where came from and where we are going. Since history often does repeats itself, it may be good, to look backwards to get a sense what actually happened, in the past. This writing will be discussing about societies that have changed, and how, human evolution helped. I will point out what I think are the most significant part of human evolution and doing that, that I write in a coherent order from the beginning of time.

One of the most astonishing things on earth is the human body. They consist of many organs that work together to maintain the person alive. The humans body composition is complex, but what was the origin? How did we become who we are today? These are the questions that intrigued me, and allowed me to understand how the human body evolved over the years. By the examination of our ancestors, and our body we will understand how we look today.

The apex of human existence is to uncover what is human existence or further what is the reason anything exists and especially what does it mean to have conscious thought; in other words, to find out what it means to be human. This can be further expand upon on as what is everyone’s individual purpose and how would those purposes change based on the social, economic, and political situations which vary between person to person and even civilization to civilization. Does being human mean one is just an animal with conscience thought or is the reason behind why consciousness something much more than pure natural selection, because according to the theory of evolution natural selection is only a need to either help keep the moto of survival of

The idea of anthropocentrism provides comfort to humans. It posits that in this messy, incomprehensible world, we are still the central species. This idea allows, and even encourages, humans to view the world through a very anthropological lens and assume that, because we are the dominant and most important species, nature works in human terms and is the domain of man. The idea of creationism is very anthropocentric itself. In the Hebrew Bible, man was created before all other animals and designed in God’s image. He was given domain over nature by God as well. This idea of human supremacy and exceptionalism has persisted into modernity, but the advent of Darwin’s evolutionary theory altered human’s perception of themselves and the natural world.

Life is evolution. Humans continuously try to keep up with the latest trends in an attempt to remain relevant in society. In the past ten years, humans have evolved immensely with the introduction, development, and integration of technology into their culture. Virtually everything can be found on the internet. Pictures and documents are being shared through cloud storage rather than being shared directly with a physical document, and doing homework online is now the norm. People have adapted to the new age, and those who have not adapted are being left behind--this is where the theory of natural selection meets modern cognitive science. Steven Pinker, the author of How The Mind Works, argues that the concept of natural selection is not as linear as society may think it is with today’s information. There is more to evolution than straightforward “survival of the fittest”. Using his background knowledge in cognitive science and the social sciences, Pinker links the biological approach to evolution with his cognitive science approach in an attempt to generate a new perspective to the theory of evolution. Steven Pinker supports his claim that the concept of natural selection is more than a simple biological adaptation, but rather a combination between biological adaptation and an adaptation to the “cognitive niche”, with historical observations, analogical evidence, and exploitation of archaeological evidence.

The theory of natural selection creates a harsher lenses in which man views fauna, one with only clinical observance and without emotion. Natural history seemingly becomes a chronicle of cruelty and triumph of the strongest and a eulogy for the weaker. Instead of being daunted by this, Charles Darwin’s reaction to this methodical cycle was relief. It can be seen throughout his ¬Origin of Species in which he uses double meanings in order to mediate the brutal perception of nature that comes from his theories. Darwin’s loaded language inconspicuously reminds the reader of moral norms and to consider nature as something separate from man and God.

Biological anthropology, also known as physical anthropology, is the study of human evolution defined by Anthropology Professor Dr. Craig Palmer at the University of Missouri.

A theory discovered by Charles Darwin, and released to the public in 1859, answered many questions for scientists who weren’t able to figure it out. Using the Theory of Natural Selection, he came up with the Theory of Evolution. In the Evolution theory, it states the genes that allow a species to thrive are passed down from parent to offspring and it also provides us with an insight of the changes an organism goes through over time, in which it relies on Natural Selection to do so. Despite doubters and opposers, there has been lots of evidence to prove it such as Biogeography, Biochemistry, relative dating, embryology, and homology. Biogeography refers to the distribution of plants and animals, while biochemistry refers to DNA similarity

The human population has always wondered where they came from, or how they came to be. Why do they have certain characteristics that distinguish them from other species, or how did they acquire these characteristics? Why do they have similar traits to other species? There are many questions about the existence of the human population that they would love to have the answer to. Unfortunately, there is not an answer that is a proven fact. Luckily, there are theories that try to explain where humans and other species evolved from. The two well-known theories of evolution are accredited to Jean Baptiste Lamarck and Charles Darwin. Jean Baptiste Lamarck developed the theory of acquired characteristics, which is often known as Lamarckism (Stanford 17). Lamarck’s theory stated that, “all organisms make adjustments to their environment during their lifetime that could be passed on to their offspring, making those offspring better adapted to their environment” (Stanford 17). Lamarck says that organisms adapt to their environment during their lives and the characteristics that they acquire during their lifetime are passed off to their offspring; The offspring are now better adapted to the environment. Charles Darwin had a different approach in his theory of evolution. Darwin believed in his theory of evolution by natural selection. Natural selection is the idea that “individuals with favorable variations would survive and reproduce, but those with

I think that it is amazing that they found the fossils of a human that looks so different than anything they have found before and that existed not that long ago. I believe based on the evidence and the different articles that it is a new species. If that truly is the case, then that is amazing to even think about. There is dissimilarity within species; there are also discrete species. The term hominid is a member of the zoological family Hominidae. Hominidae incorporates all species instigating after the human/African ape familial divided, leading to and as well as all species of Australopithecus and Homo.

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.

When we think about the evolution of modern humans we think about two basic theories. The first theory is the “Multiregional Variation theory which is the different human populations or cultures had independent origins and are evolved in isolation from one another. The second theory is the “Out of Africa “theory. This theory is basically when humans evolved in Africa between 200,000 and 100,000 years ago. After these humans evolved they left Africa after evolving. Both of these theories both support and have evidence about human evolution beginning in Africa.

Human evolution according to research started over 6 million years ago. The outcome of the evolution process is the current human beings. Scientific studies have revealed over the years a remarkable affinity between the chimpanzees/Apes and human beings. Even though this reality is not a definitive prove that human beings evolved from apes, it does show that the human beings are in one way or another related to other primates. Scientists suppose that the humans and the primates shared a common ancestor. The subject of what makes humans what they are and their origin has been the exclusive purpose leading to many scientific studies globally (Coolidge & Wynn, 2011). Studies believe that Africa was the origin of evolution millions of years ago. Fossil remains have been discovered in different parts of Africa as well as other regions of the world. Different hominins have been discovered around the world in the last 1 million years. Thus, the different discoveries have led to comparisons between the various species of hominins to clarify on their similarities as well as differences. This essay seeks to explain whether they were distinctively different species or regional versions of the same species.

Although life brings many difficult challenges and hardships, it is also a beautiful thing because it portrays the vast journey of humanity. In the Catholic Religion, it states that God is the creator of mankind. However, this ideology leaves a mystery as to why human life is immensely diverse. One of the noblest characteristics of life is that it creates unique and different organisms. The spectacular journey of humankind first originated hundreds of millions of years ago through the development of cells.

Evolution is the idea of similarities among organisms the indicate a common ancestor from which all species link back to. Michael Park states that "Different species exist because, in the continuous process of adaptation, species can and do give rise to new species. Environments to which species are adapted are always changing (Park, 47)." Human evolution is the process of humans changing from primate ancestors to what is now modern-day homo sapiens. The shared DNA could have shaped our individual susceptibility to modern day diseases or adaptation to new environments and climates. Evolutionary history does violate how humans see themselves in the modern world. However, I believe this is a natural part of evolution that is brought about by the long-term evolution of a single species. In his book park explains this idea through the idea of adaptation stating that "Each living species has its own unique set of adaptations to its own unique environmental niche, and these can be described (Park ,48)." The way humans view themselves is part of the process of evolutionary history itself the modern worldview is a by-product of our evolutionary history. Park states that "In fact, we are unique in that we can consciously change certain behaviors if they are not giving us the desired results (Park, 49)."
