The Evolution of Humans 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. Human evolution is “the process by which human beings developed on Earth from now-extinct primates” (Human Evolution, 2017). It is thought that human evolution began with a species of ape called Australopithecus, or one referred to as Neanderthals. These species most closely resemble the beginning of humans because they were a type of ape that walked up-right. As time progressed our primates began to adapt to the environment, and slowly changed into who we are today; Homo sapiens. Charles Darwin— an English naturalist, geologist, and biologist—was known for developing the theory of evolution. He explained that evolution was a “decent with modification” (On the Origin of Species, 1859). This meant that we all originated from a different species. However, we do not look exactly alike because we adapted to the environment we were exposed to. Although we all originated form a certain species, after undergoing serval mutations throughout generations to ensure
Describe the major developments of early human and social evolution. Throughout, discuss tool manufacturing, language development, agriculture, social behavior, and population growth.
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.
Human evolution is the biological and cultural development of humans. A human is any member of the species Homo sapiens, meaning "wise man." Since at least the Upper Paleolithic era, some 40,000 years ago, every human society has devised a creation myth to explain how humans came to be. Creation myths are based on cultural beliefs that have been adopted as a legitimate explanation by a society as to where we came from.
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.
This chapter beings explaining the evolution of mankind. Prior to 11,000 BCE, all humans were equal. Due to our evolutionary past, we branched off from apes to humans and spread around the world. Nearly 4 million years ago, humans began their mark on earth in Africa. Jared Diamond compares human development on all seven continents about 13,000 years ago. Although many early humans were found primarily in Eurasia and Africa, over time they expanded and gained new territory. The early humans created tools as they evolved, and many became hunter and gatherers. Then, human history made a Great Leap Forward around 40,000 BCE. The Great Leap Forward was when the earliest humans created new technology and exciting innovations that did not exist previously
The theory of evolution sets forth an explanation of how all of the living species on Earth came to be. The theory as we know it today, written by Charles Darwin, states that all the living species of today – humans included – evolved over time; we can see evidence of their evolution in the fossils of now-extinct species. In his book Origin of Species, published in 1859, Charles Darwin wrote that species evolve over time through a mechanism known as “natural selection.” Basically, each species is born with a multitude of traits, some more favorable to survival than others. Because some traits encourage survival more so than others, the animals equipped with those traits tend to breed more than the animals that lack those traits. Over time, more and more offspring are born with these favorable traits and less are born without them; thus, the species evolves. In his 1871 book, The Descent of Man and Selection in Relation to Sex, Darwin surmised that where humans are concerned, natural selection helped humans evolve in addition to a concept known as “sex selection.” Similar to natural selection, sex selection is the process by
Throughout time human species have evolved. It all started seven million years ago. Many different kinds of ancient humans have roamed Earth. The first species were discovered in Africa and later in Asia, Europe, Australia, and the Americas. Paleoanthropologists, geologists, anatomists, and paleoecologists determined when and where new species evolved by analyzing hominid fossils. They can also tell us how species lived and died, which other species they are related to, what was the climate like, and the plants and animals people relied on.
Evolution is not just a story about where we came from, but an epic at the center of life itself. Evolution is the process of inheriting traits through DNA over successful generations. Charles Darwin, a naturalist and geologist synthesized a theory later known as Darwinism, which explains that "all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual 's ability to compete, survive, and reproduce" (Darwin, 1859). Humans have evolved over a period of almost 1.5 millions of years with creation, development and destruction of many characteristics. But how did humans look thousands of years ago, how would we look thousand years from now and how did early humans
Human evolution is the process by which human beings developed on Earth from now-extinct primates. Scientists theorized that humans are descendants of the early primate that over time, evolved into modernized species due to adaptation to the changes in the surrounding environment.
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.
Merriam-Webster says the definition of evolution is, “descent with modification from preexisting species: cumulative inherited change in a population of organisms through time leading to the appearance of new forms: the process by which new species or populations of living things develop from preexisting forms through successive generations.”1 Science says that humans are descendants of apes. So, we are related to chimpanzees, gorillas, and orangutans also. Human evolution (anthropogenesis) is the part of biological evolution concerning the existence of Homo sapiens as a distinct species from other hominins.2 Science says that the homo genus diverged from the australopithecines about 2 million years ago in Africa.
Human evolution is the gradual process in which people, or Homo sapiens, originated from apelike ancestors. Scientific evidence, particularly in the form of fossils and secondary remains, show that the physical and behavioral traits shared by all people evolved over a period of approximately six million years. Humans are primates. Both genetic and physical similarities show that humans and the great apes (large apes) of Africa, chimpanzees (including bonobos, or so-called “pygmy chimpanzees”) and gorillas share a common ancestor that lived between 8 and 6 million years ago. The volume of fossils found in Africa suggests that most evolution occurred there and is likely the place of origin for early humans. This brings to fruition the “out of Africa” theory, also called the “single-origin hypothesis.”
Throughout history, humans have asked many questions in regards to our own beginnings. Religion and science have examined what makes us who we are, and have tried to answer the enduring question of our own modern origins. Scientifically, theories are still debated as to when, where, and how modern Homo sapiens came to be what they are today. There are two major theories that now dominate the discussions of experts in the field of biological anthropology: the “Out-of-Africa” model and the “Multiregional” model of evolution. Stringer and Andrews argue that genetic and paleontological evidence supports a more recent Out-of-Africa model as opposed to a more drawn out Multiregional method that also incorporates gene flow (1263). In contrast,
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.
While time travel still remains elusive to us, scientists have been able to discover things about our past as a species that were practically inconceivable over 150 years ago when Charles Darwin released his book entitled The Origin of Species. They have especially uncovered many pieces to our still incomplete puzzle over the past 20 years so that we now have a nearly complete idea of how our species Homo sapiens came to be. This story of our history includes dozens of species’ and hundreds of fossils and bones, yet fairly few complete or even partial skeletons. Hominids have gone through many changes to get from one of our earliest species’ Ardipithecus ramidus to Homo sapiens which scientists have been able to discover
