Evolution of the Hominids

The Homo habilis was known as “the skilled human or handy man” (Standford 273). They got this name because they made tools. Homo habilis have a brain size of aproxamiltly 509 cc to aproximitly 775 cc. They also have a encephalization quotient (EQ) of about 2.73 to 3.38.

Hominids are ancestors of humans who are primates. Primates are known to have grasping feet and hands, fingernails instead of claws, fingerprints, forward facing eyes, and are known to be smarter than other animals. Out of all the primates, chimpanzees are the closest to humans. Ninety-nine percent of human genetics match chimpanzee genetics. Ever since humans started to evolve, they started to develop distinct features that are different from these primates, which was called divergent evolution. For example, humans are bipedal, while most primates are quadrupeds. As time went on, they evolved to the present-time humans the world has today. But what happens next? Because you can’t accurately predict the far future, people like scientists can only predict how humans are going to change and

The human brain is a feat of evolution: it has allowed humans to have complex thoughts, conscience, build tools, create fires, and much more. Humans did not acquire this simply by chance. Evolution throughout our ancestral past has shaped and moulded the human mind to its state. The earliest of ancestors, including apes, had very small brains, but as evolution progressed, so too did the human brain. The rapid progression of human intelligence has been attributed to environmental changes causing humans to change with their surroundings for survival. This lead to the expansion of specific areas of the brain, vastly differing maturation of humans compared to our

Introduction This first lecture is designed to introduce the primate order in terms of its classification and to familiarise you with the animals so that the rest of the course makes some sort of sense. I will cover a working definition of what makes a primate, give you a general classification scheme, describe the major features that identify the groups within the classification and discuss some of the controversial areas of the classification. I shall treat the taxonomy as a synonym for classification which seems to be its commonest current usage, although you should be aware that some people consider taxonomy to be more about the principles behind the classification than the classification itself.

There is a circumstance that has beset the understanding of evolution over time that there is no general theory involving primate evolution. Most of the theories are just mere speculation. Over the years, primates like gorillas, chimpanzees, and baboons all happened to have their turn in evolution. It was previously presumed that the taxon of interest happened to have the exact similar physiology and ecology as the analog taxon (Rafferty, 2010).The majority of the first primate species theories have been utilized because they solely share one fundamental characteristic with the hominines with the chimpanzees as the phylogenetic cousins. This paper addresses the different ecological conditions that handled the evolution of primates. It

Each and every primate’s exhibit changes for climbing trees and shrubs and has evolved into two major groups: Prosimians and also Anthropoids.

New research conducted by Canadian experts at the University of Lethbridge suggests that new behavioral trends are manifesting among primates, which has interesting implications about how the behavior of all animals undergoes its own sort of evolution, including that of human beings. The study shows apparent sex acts on the parts of female, Japanese macaques on sika deer. These acts of interspecies relations were observed in Minoh, Osaka—a city in central Japan. As uncommony documented as interspecies relations can be, they are a known phenomenon, and it’s been observed as early as the Holocene epoch or even the Pliocene epoch by way of the extinct mammoth.

The evolutionary of human living has taken place over millions of years of geological time. It has evolved millions of generations, and billions of individuals. The human evolution is not understandable completely yet. Evolutionary change within a population can take place at different time and different rates, which yield different consequences. This process still taking place in the natural selection and human evolution. One species may be merged to the new species or developed to the next stage of the same species. Homo Habilis, Homo Erectus, Homo Heidelbergensis, and Neanderthals were the close ancestors of modern human, which developed from Australopithecus afarensis.

The Neanderthal roamed the lands of Europe for tens of thousands of years. But about 30,000 years ago, they became extinct, vanishing from the earth. (Homo Sapiens Versus Neanderthals). Only 15,000 years before, our ancestor Homo Sapien had expanded from Africa into Europe and Asia.(Humans Vs. Neanderthals: How Did We Win? : DNews.) There are many different theories on what happened to Neanderthal, and how their interaction with Homo Sapien changed the Neanderthal world. The Homo Sapiens were more advanced and adaptable, and they could use the resources better than the Neanderthal. The Neanderthal also interbred with Homo Sapien who outnumbered them ten to one. (Humans Vs. Neanderthals: How Did We Win? : DNews.)But eventually the Neanderthal

Approximately 4 million years ago a wonderful evolutionary phenomenon was happening in Africa. Early hominids, man’s ancestors, were beginning a giant leap in their evolution. These hominids were moving out of the forest and beginning to walk upright, out on the open plains (Fagan, 98). This change from quadrupedalism was the most significant adaptation that ever happened to these early hominids. It caused many adaptations that make man what he is today. This process occurred in early hominids for many different reasons, each reason helping to perfect the upright walking posture. Bipedalism is thought to have occurred because of changes in environment, feeding habits, thermal regulation, and

“What makes us human?”, is an unanswered question asked by many. Is it because of our ability to have empathy for others? Or is it because of our cognitive ability which allows us to look into the future? One of the main arguments made that separates humans from animals is our communication style; our language. Is language inherently unique to human? To answer such a question, we first operationally define language as; “a system of communication based upon words and the combination of words into sentences” (University of Oslo). The purpose of language is for us to be able to convey an infinite amount of ideas to one another. Sign language in general also falls under this definition as it has a complex system of rules and syntax that allow the signed figures to function as words. Animal communication on the other hand, is operationally defined as, “the transmission of a signal from one animal to another such that the sender benefits, on average, from the response of the recipient” (Pearce 1987). With this in mind, current research has shown that the answer is that language is inherently unique to humans.

According to physical evidence, and theories, scholars have concluded upon a whole hypothesis. Based on their knowledge and belief, modern humans diverged from Homo sapiens between 200,000 and 150,000 years ago specifically in Africa, that between 125,000 and 60,000 years ago members of Homo sapiens left Africa, and that these

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.

Our communication process or the way we attribute symbolic meanings to words and gestures, in order to express ourselves is shaped by the society in which we evolve. This shared use of codes within a given group of persons, also leads to a common philosophy of life, ideas or

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.
