Humans are extremely complex and unique beings. We are animals however we often forget our origins and our place in the natural world and consider ourselves superior to nature. Humans are animals but what does it mean to be human? What are the defining characteristics that separate us from other animals? How are we different? Human origins begin with primates, however through evolution we developed unique characteristics such as larger brain sizes, the capacity for language, emotional complexity and habitual bipedalism which separated us from other animals and allowed us to further advance ourselves and survive in the natural world. Additionally, humans have been able to develop a culture, self-awareness, symbolic behavior, and emotional complexity. Human biological adaptations separated humans from our ancestors and facilitated learned behavior and cultural adaptations which widened that gap and truly made humans unlike any other animal.
Biological Evolution
Biological evolution is the change in the inherited and genetic characteristics of a species. Much of what makes us human is our physical appearance and biological adaptations. Human ancestry originates in primates and over time, we have physically evolved a great deal in order to become the modern humans that we are today. Humans have larger brain sizes, longer legs, and are habitually bipedal all of which biologically separate humans from other animals and create the human identity.
One of the most important and pivotal physical and biological adaptations that separate humans from other mammals is habitual bipedalism. According to Darwin, as restated by Daniel Lieberman, “It was bipedalism rather than big brains, language, or tool use that first set th...

... drawn. What makes us human? Through the examination of human evolution, both biological adaptations and cultural adaptations which are distinct to humans can be recognized. Biologically speaking, humans are unique in that they are bipedal, they have larger brain sizes, and longer leg length. When examining the cultural evolution of humans we have a complex language system, we live in communities, engage in symbolic behavior, and act through emotional impulses. While we are often considered to be superior to all other animals, it is important to recognize that while we are animals, we have very distinct characteristics and adaptations that separate us both biologically and culturally from all other animals.

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. Both the Savanna Theory and the Aquatic Ape Theory offer solutions to how and why humans evolved into bipedal toolmakers. But with enough questioning, each loses its accountability to rhetorical science.
What does it mean to be human? To most people it means being high on the food chain; or having the ability to make our own choices. People everywhere have a few things in common: We all must obey Natural laws, and we have preconceived ideas, stereotypes, and double standards. Being human is simply conveyed as human nature in “The Cold Equations”, by Tom Godwin, where the author shows the common ground that makes each and every one of us human.
...om simple ancient form that already existed for millions of years in development. Human have features that are modified and rearranged in a more recent way, which make us unique. This is not saying we are the only living things that are unique, fish have their own modification that derived from the chordate ancestral. We are living things that cannot make our own food, giant multicellular organisms were enhanced through our bodies by the evolutionary process so that we could survive and reproduce in this planet. We are built to accommodate the environment that we live in. We are not perfect at adapting to our environment, but more like the good enough for now, in other words just the working process of evolution.
Biological evolution is a change in the characteristics of living organisms over generations (Scott, 2017). A basic mechanism of evolution, the genetic drift, and mutation is natural selection. According to Darwin's theory of evolution, natural selection is a process in nature in which only the organisms best adapted to their environmental surroundings have a higher chance of surviving and transmitting their genetic characters in increasing numbers to succeeding generations while those less adapted tend to be eliminated. There has been many experimental research projects that relate to the topic of natural selection and evolution.
Bipedalism is a form of locomotion that is on two feet and is the one factor that separates humans from other forms of hominoids. The first bipeds are believed to have lived in Africa between 5 and 8 million years ago. (Haviland et al. 2011, pg. 78). The evolution to bipedalism resulted in various anatomical changes. To be able to balance on two legs, the skull must be centered over the spinal column. As bipeds evolved, the foramen magnum, the opening at the base of skull for the spinal column, moved from the back of the skull to the center. The spinal column also evolved from a continuous curve to a spine with four concave and convex curves. (Haviland et al. 2011, pgs. 79, 80). Another change was the widening of the pelvis which gives a wider plateau for more balance when walking on two legs.
From all existing creatures, we humans differ because we are able to use our brain to make decisions. In
Human advancement, otherwise called hominization, is the transformative procedure that prompted the development of anatomically modern humans, starting with the developmental history of primates – specifically variety Homo – and prompting the rise of Homo sapiens as a distinct species of the hominid family, the considerable gorillas. This evolutionary procedure was
According to Darwin and his theory on evolution, organisms are presented with nature’s challenge of environmental change. Those that possess the characteristics of adapting to such challenges are successful in leaving their genes behind and ensuring that their lineage will continue. It is natural selection, where nature can perform tiny to mass sporadic experiments on its organisms, and the results can be interesting from extinction to significant changes within a species. Human beings are no exception to biological evolution. Like other organisms around the world, humans have significantly changed over time and have developed all sorts of diverse characteristics.
The facts and research on evolution is so important in our wold today that we all must really understand it. Correctly understanding evolution is crucial for understanding biology as well. Scientist Theodosius Dobzhansky said, “Nothing in biology makes sense except in the light of evolution.” Evolution proves to be the only scientifically backed up explanation for human diversity. It shows us the connection between vastly different forms of life. As well as showing the changes and evolution of popul...
It has long been believed that humankind owes its survival to bipedalism, which is the ability to walk on two legs. This is the first human characteristic to distinguish human from other primates. It is habitual, meaning that it is the primary form of transportation. This characteristic thrived in a time where forests were shrinking and the environment consisted of grasslands. The feature bipedal locomotion leads humans to manipulate their surroundings, bypassing their biological features and being given to the ability to live anywhere, and in any environment. Although developing into bipedal organisms hominids were taking a big gamble. With all the benefits of bipedalism, there are also many disadvantages. In some cases these disadvantages
The members of the Homo genus possess a combination of unique features that distinguish them from other related species. At the time that each respective species was alive, they were able to walk upright on two legs, use their large brains for the benefit of their species, and could thrive in many geographically and climatically diverse areas of the world. One of the most mysterious quandaries in science is how the lineage of the Homo genus became so different from their primate relatives. Bipedalism, brain size, and location diversity all have a common link that may explain this difference – dietary evolution allowed humans to adapt to their surroundings, and in turn, become a more advanced species. The Homo diet evolved in relation to food availability and nutritional necessity. With the ability to maintain a proper diet, the species of the Homo genus were able to flourish and advance toward the development of modern Homo sapiens.
What does it mean to be human? Sure, one must have the usual physical features such as fingers, eyes, arms, hands, feet, etc., but what does it really mean? Must the human be able to speak? To take upon the actions of themselves? Whatever it means, it can be interpreted in any way from anyone. The physical attributes of any human can be compared to those of our evolutionary ancestors. However, it is possible to believe that there are many characteristics that make a human, but only six define the true, ideal human.
Evolution is the complexity of processes by which living organisms established on earth and have been expanded and modified through theorized changes in form and function. Human evolution is the biological and cultural development of the species Homo sapiens sapiens, or human beings. Humans evolved from apes because of their similarities. This can be shown in the evidence that humans had a decrease in the size of the face and teeth that evolved. Early humans are classified in ten different types of families.
The evolution of humans was (and is) a very important time. The first being of evolution was Australopithecus Afarensis or “Lucy”. Then we moved on to Homo erectus and Homo Neanderthal. When the weather got hotter, we were Homo Sapiens Sapiens and finally, the modern man. This evolution did not happen overnight. It took millions of years. The past is hardly forgotten, but the imminent is next.
As everyone knows, the history of human evolution originated from more than five million years ago (Pickrell, 2006). Human is the most intellective living being on the Earth, even in the developed universe. With the development of human being, the beginning of human started to be discovered. This essay will focus on the evolution history of human being. It will explain three most significant time slices of human evolution.
