The Evolution Of Human Beings

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.

They are different in their tools adapting to their environment, social organizations, religon, goverment, and clothing.

In conclusion, the lives of the people living in the Paleolithic and the Neolithic time period were different in many ways and a like also. Through the improvements in technology, education, and culture they were able to enhance the quality of life throughout these two periods. As man's mind increased, it led into the new age, and the start of what may be civilization, as we know

There are major events that mark the beginning and end of this period. The period began at around 9000 B.C.E. when the popularity of agriculture grew. The domestication of animals like sheep, cattle, goats, and pigs began to appear within civilizations. The end of this period came at around 1000 B.C.E. when civilizations began focusing on strengthening their culture and politics. This took place once the civilizations did not have to devote all of their focus to staying alive.

timeline of modern humans, Homo sapiens, and how long they have been in existence. According to mainstream science, popular belief holds that the history of our species is confirmed to be confined to the past 12,000 years. This figure is a culmination based on what we know about evolution and what we have been able to gather through fossil analyzation and dating of artifacts as well as human remains. Although the subject of human antiquity, also referred to as human origins, does not prompt a great deal of debate there may actually be the need for some. A reexamination of the notion that humans have only existed a mere 12,000 years should be considered as there may be evidence to support a much greater antiquity of modern human life. Alternative researchers have offered up evidence of “forbidden archeology” that contradicts the mainstream beliefs of human origins, however these discoveries seem to have been swept under the scientific rug.

The liver’s complex biochemical process of detoxification is a two phase process, converting the byproducts of metabolism and toxins to render them into safer substance. Phase one, an enzymatic process, involves approximately 100 enzymes in the cytochrome P450 system. In Phase one, the chemical reaction known as biotransformation changes the toxin in to a less toxic, water-soluble substance to allow it to be safely excreted through the kidneys or colon. Enzymes do this through oxidation, the loss of electrons, or reduction, the gain of elections. Most of the time, the enzymatic reactions in Phase one decrease the toxicity of the substance, however, a more toxic intermediate substance may be produced, this is known as bioactivation.

     The Paleolithic Period is the earliest time period man has been alive, and the longest of the Stone Age's. It dates from 2,000,000 B.C to 10,000 BC The people of the Paleolithic Period lived simple lives, which consisted primarily of survival. Man's life was simply to hunt, eat, and survive, while the woman’s job was to gather and watch over the children.

Homo erectus was first found in Africa and the fossilized remains dated 1.8 and 1.0 million years old. The Homo erectus traits are very similar toward the modern human traits. Homo erectus brain size was smaller than the Homo sapiens. Homo erectus had a brain size of approximately 650 cc and Homo sapiens had a brain size of approximately 1251

The Paleolithic and Neolithic periods displayed major cultural differences in religion, lifestyles, government, and technology. “Culture is the way of life of a group of people. Culture includes common practices of a society, its shared understandings, and its social organizations are always changing” (McDougal, World History: Patterns of Interaction, 2004) The Paleolithic time period was full of inventions and was a time where new technology and lifestyles were blossoming through all cultures. Tools made out of pressure flaked stone and rock were created during this period to help with everyday tasks. The Paleolithic period was also the period where the creations of fires were discovered along with religion and languages. The Neolithic age, however, was more technologically improved, than the Paleolithic age. This was the start of the agricultural revolution and the start of civilizations and societies. These two periods were ever changing.

Two learners have been selected in St. Mary’s East Primary School to be the central focus of analysis within the study. The participants, *Dylan and *Cain, are two Caucasian males within an 17 student mixed gender inclusion kindergarten classroom. To gather data that will benefit all learning styles within the classroom, *Dylan was chosen as he is classified as gifted, and *Cain because he is currently on an individualized education program (IEP). The results from a pre-test and an end of unit number formation test as well as informal observations, visual representations on whiteboards, and discussions from both focus learners, will be analyzed to determine the effectiveness of assessments for improved knowledge of number formation between

The next species to appear were the Homo erectus which might have descended from Homo habilis. They were the first human whose fossils were found outside of Africa. They also had larger brain than the species before them. Homo sapiens sapiens came after the Homo Neanderthalensis; they are the only human species around. This could have been due to the result of increase brain sizes that allows more cognitive abilities that help them adapt to different environment changes and hence survive. Global evidence have been found of art, music, and culture and advanced tool making. In Mithen’s 3 phase of mind proposes that the shape of the Neanderthals’ frontal lobe was similar to the one of the modern Homo sapiens and this indicated that they were able to cope with complex cognitive functioning. Evidence for this could be explained using the phonological approach by Frank Gall (1758-1828).

Argument essay Do curfews keep teens out of trouble? A curfew is when your child can not be outside walking either by them self or with friends. If the police sees him i think that he can be arrested. My opinion about curfews keeping teens out of trouble is that it kind of does and it kind of doesnt like teens can be doing things that they are not suposed to be doing and the other thing is that the teens can just be doing an all nighter.(when they don not go to sleep for a whole day).

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.

The ‘out of Africa’ theory implies that Anatomically modern humans evolved in East Africa between 400,000 and 200,000 years ago and began to disperse throughout the world roughly 70,000 to 135,000 years ago. In 2011, scientists came to the conclusion there were likely two major waves of migration out of Africa - the Early northern Africa dispersal and Southern Route dispersal.
