Two Points Made About Human Evolution

Why haven’t primates evolved like humans? This question that some may be asking. Humans and primates walked along each other for thousands of years, but then humans began using tools while the others were still picking fruit and eating it. Why did humans and not primates evolve? This paper will answer this question.

According to Diamond, Human ancestors moved to Eurasia around 1 to 2 million years ago and after human fossils began to resemble modern Homo sapiens and archaeologists called that period the Great Leap Forward. According to “Human Evolution and the Great Leap Forward - By Advocate De Waal Lubbe,” Scientists have estimated that humans branched off from their common ancestor, with chimpanzees, about 5-7 million years ago. Several species and subspecies of Homo evolved and are now extinct. These include Homo erectus, which inhabited Asia, and Homo Sapiens Neanderthalensis, which inhabited Europe. Archaic Homo sapiens evolved between 400,000 and 250,000 years ago.

Human migration started from Africa , then led out to the Middles East. From there they went westward into Eurasia and eastward into Asia, all 45,000 years ago. With the

The most recent ancestor to the modern human, Homo neanderthalensis existed between 300,000 and 35,000 years ago. Originating in Africa, ancestors of the early Neanderthals migrated northwards almost 800,000 years ago. These migrants colonized much of the Old World with the majority based in Europe and small groups scattered throughout the Middle East and Asia. Historically, the Neanderthals were among the most resiliant creatures to exist on Earth. As a population, they thrived during the European ice age 40,000 years ago. This ice age enveloped the majority of Northern and Central Europe and due to their physique were the Neanderthals were able to surive. Physcially, the Neanderthals were larger and more muscular than today’s human

According to anthropologists the first human beings lived in Ethiopia, Africa around 2 million years ago for example: Lucy known as the oldest human found there. The most probable reason why the first human left Africa is because of the Ice Age. The cold made life so difficult to survive and somehow reduced in their population. They went through a land bridge, which existed to connect North America and Asia during the Ice Age.

Scientific findings suggest the first humans were from northeastern Asia during the last Ice Age.

As earth’s last continents to be colonized by humans, all skeletal remains found in the Americas are modern Homo sapiens. Modern human dispersal out of Africa across Eurasia began about 50 ka and reached the Americas around 15ka (Goebel, 2008). The last global maximum took place around 20ka when sea level was 60ft lower than present day and the land bridge between Beringia and Tierra del Fuego was exposed. Routes of migration are hard to estimate from genetic data. Archaeological data tells us that humans entered America around the end of the Wisconsin glaciation, 11ka, via an ice-free mid-continental corridor. This model would support a relatively even latitudinal migration southward. An alternative migration route is along the Pacific coasts. This model could

Neanderthals were hunter-gatherers who moved across Europe with the advance and retreat of the Ice Age glaciers. Their total population probably never exceeded 100,000. From 180,000 to 130,000years ago large glaciers covered much of Europe and Neanderthal remains are scarce. After 130,000years ago, tool technology developed rapidly to become the classic Neanderthal technology called the

Europe had a lot invasion by barbarian hordes, which caused destruction to this era. According to document

From about 2000 BC people speaking Indo-European languages began to spread through Europe, eventually reaching the Atlantic coast and the northern shores of the Mediterranean. They also spread

Several different hypotheses have been formulated to explain the extinction of Neanderthals, from climate changes to intoxication from cave-associated contaminants like smoke, from cannibalism to diseases (Herrera et al., 2009). It is only certain that Neanderthals disappeared from fossil record after the arrival of modern humans, around 40,000 years in Asia, and 10,000-15,000 years in Europe (Shreeve, 1995). Fossil evidence shows the presence of modern humans in Middle East from 130,000 to 75,000 years ago, in the same areas where Neanderthals retreated between 65,000 and 47,000 years ago (Mellars, 2004).

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.”

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 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.

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.
