To the ongoing question as to how humans evolved has still been a debate over several decades. Homo sapiens is a scientific name given to humans. Homo sapiens are classified under the kingdom-Animalia, phylum-chordata, class-mammalia, order-primates, family-Hominidae, genus-Homo and species-sapiens. According to Linnaeus Carlos, scientific way of classifying living organisms (Relethford, 2010). According to Relethford, Hominin is a tribe that comprises of humans and their closest ancestor. Hominin family has shown some resemblances with the evidences collected from fossil records as well as the evolutionary processes to the mordern humans. This article will try to describe the evolution of homonin tribe from the time period of Homo habilis to Mordern Homo sapiens. It will emphasis on the cranial capacity “skull proportions”, tools used and the cultural behavior.
Homo habilis species was first found in East Africa at the Olduvai George site, approximately 1.9- 1.4 million years ago (Spoor et al. 2007). This species was also known as “Handy man” or “able man”. Homo habilis had a smaller brain of about 630 C.C. compared to living humans today (Relethford, 2010). Post cranial skeleton show similarities to Austrapiths and an evidence to bipedalism however, they retained climbing abilities ( McHenry 1992). The simple stone tools found associated with Homo habilis were referred to as Oldowan tools. There is still no clear evidence whether these species relied on scavengers left by the carnivores or did they associate themselves in hunting by the use of the stone tools ( Relethford, 2010).
Apart from Homo habilis, Homo erectus was also found in East Africa around 1.9 million years ago (Relethford, 2010). Homo habilis had more prim...

Chinese and Malaysian Homo Sapiens have very close features to the Neanderthal. The skull analysis of Neanderthals and Homo sapiens are usually considered more accurate if the entire skull is examined, rather than certain ...
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.
The human archaeological record is a long and undefined story that may be the most complex question researched today. One of the big questions in human history is the disappearance of the Neanderthal people from the archaeological record around 30,000 BP. While for thousands of years Neanderthals and Anatomically modern humans crossed paths and perhaps lived in close relations, we have yet to really understand the degree to which they lived together. My hypothesis is that these two hominids, Neanderthals and Anatomically Modern Humans, interbred exchanging genes after Modern Humans dispersed from Africa and creating like cultures and material remains. The differences between Neanderthal and Modern humans are not only physical but also genetically evolved and this research will determine an estimated amount of admixture between the two groups.

This paper has shown how Homo sapiens had several advantages over the Neanderthals including better diets, better tools and just better luck. The Neanderthals could not survive the harsh climates they were thrust into and eventually died out. In this paper I looked at how Homo sapiens and Homo neanderthalensis had co-existed but the disappearance of the Neanderthal ius due in some part to the appearance of the more culturally advanced and genetically superior Homo sapiens. Although the How and Why of how Neanderthals went extinct, it is clear that Homo sapiens had a part in their demise. In the last one hundred and fifty years that we have been studying humans we have seen them come from savage brutes, to Homo sapiens respectable contemporary. If we had not gotten lucky in the past, Neanderthals could be studying us today.
The species A. afarensis is one of the better known australopithecines, with regards to the number of samples attributed to the species. From speculations about their close relatives, the gorilla and chimpanzee, A. afarensis’ probable social structure can be presumed. The species was named by Johanson and Taieb in 1973. This discovery of a skeleton lead to a heated debate over the validity of the species. The species eventually was accepted by most researchers as a new species of australopithecine and a likely candidate for a human ancestor.

“The scientific study of how humans developed did not begin until the 1800s in Europe. Until that time, people relied on religious explanations of how humans came into existence. Starting in the 1500s a scientific revolution began to sweep Europe. Thinkers started using scientific methods and experiments to try to better understand the world and the creatures living in it. Eventually these methods were turned to the question of human origins” (The Nature Of Human Origins, 1). Earth made it possible for species to change over time because Ancient Earth provides ability to plenty of time.The Homo Sapien a is very complex creature. The species started off very simple by living in caves and surviving with little food and then later evolved into a species that were able to do many more complex things. The first species was Sahelanthropus tchadensis They were one of the most simple humans in that time period and on. They had very small skulls compared to Homo Sapiens today and their motor skills were just the same. We have evolved and changed for the better both mentally and physically. The Evolution of Homo Sapiens started off simple, such as the Neanderthals, and now we are the most advanced species to ever walk the planet so far.
These species have been named Australopithicus, robust australopithecines, Orrorin tugenensis, Homo habilis, Homo erectus, neanderthal, and Homo sapiens. These early hominids and modern humans really show how the features and behaviors have really changed over time. Austalopithicus, meaning “southern ape” was the first specimen to be found. The Austalopithicus was found in Africa and was known to have lived from 4.2 to around 1.0 million years ago (Standford 251). They had a small body like an ape that would weigh approximately 64 to around 100 pounds.
The Neanderthals are an extinct species of human that lived in ice age Europe between 120,000-35,000 years ago. This species is known for their receding forehead and prominent brow ridges. We know this species as the uncivilized or unintelligent person or group. Neanderthals are often portrayed as “unintelligent cavemen in animal-skin clothing.” Scientists’ first thought the Neanderthals’ were subhuman, but that thought is beginning to change. The original name given to the Neanderthals when they were first discovered was ‘Homo Neanderthalensis’ and they were considered to be an ancestor to modern humans. “Forty-four years after this biased classification, Neanderthals were reclassified as a human subspecies Homo sapiens Neanderthalensis and
About fifty thousand years ago, the human cultures started to be more and more similar to modern culture. The hominids killed animals not only to feed themselves but also for the production of clothing (Pickrell, 2006). The hominids had the sense of shame. They used hides to cover their body. Besides, the hominids have the thought to bury their companions (Pickrell, 2006). It is an idea of group or family. With the final formation of human society, people developed and valued quickly. The oldest cave painting had more than thirty-three thousand years’ history (Pickrell, 2006). It is the proof of original humans’ pursuit of art. Almost ten thousand years ago, the systematic agriculture appeared, developed and spread with an amazing speed (Pickrell, 2006). Humans started to plant cereal and raise and train livestock. After that, the Bronze Age carried on the Stone Age (Pickrell, 2006). The change of tool materials helped people have higher efficiency when they were working. At the same time, the first recorded human culture appeared in Mesopotamia (Pickrell, 2006). Until this time point, human beings finished their evolution from ancient apes to modern humans. The process, which had experienced more than hundreds million years, was the most wonderful evolution on the
