communication (language). These are the 3 traits that makes us human. To have bipedalism you have to have the ability to walk upright. According to the text‚ History Alive it states that “As scientists assembled the bones‚ they observed that these hominids (Homo Erectus) stood upright.” This is important because this shows that around two million years ago people were able to walk on 2 feet and use their hands for other things. For us modern humans‚ we are able to walk on our two feet and are able to walk

Abstract For the following experiment‚ a Diels-Alder reaction between maleic anhydride and anthracene was conducted. Reflux mechanism was used for the reaction to occur. To increase the speed of the reaction‚ xylene was used because of its high boiling point. After the reaction was complete‚ 1.08g of the off white product was obtained with a yield of 69.7%. It was not clear if a pure product had been formed because time constraints did not allow us to perform thin layer chromatography. Introduction

Though technically defined as an archaeologist‚ Mary chose to follow a route of interesting research relating to physical anthropology. She is known mostly for the excavation of a two million-year-old fossilized human skull in 1959. She has also worked to help the world understand that the evolution of humans follows a principle rather than a theory. The name Leakey is synonymous in most people’s minds with the successive dramatic discoveries of fossilized hominid bones and stone artifacts that

who lived about 4.5 million years ago. Next came A. Anamensis‚ A afarensis‚ A africanus‚ A. acthiopicus‚ a boisei and a. robustus. Ausralopithecus boisei roamed the earth as early as 1.1 million years ago and was on earth at the sametime as homo habilis and homo erectus. Most of the australopithecus fossils that have been discovered have been found in eastern africa and have been dated between 4.5 million and 1.1 million years old. There has also been evidence that the australopithecus "man" lived

Between 10‚000 B.C‚ the development of human kind underwent many significant changes that eventually transformed the modern world. Homo sapiens transitioned from the Paleolithic age to the Neolithic era and had a significant impact on the development of civilizations. Their changes had political‚ social‚ and economic effects on the development of humankind. They were thinkers‚ they though of solutions for the many problems that they encountered. Experience taught Stone Age people the difference between

Neanderthals‚ also known as archaic homo sapiens‚ that inhabited Europe‚ Africa‚and Asia 300‚000 years ago. Controversies have surrounded on whether they were considered modern human when their fossils were first discovered in Neander Valley‚ Germany in 1856. At first‚ Neanderthals were considered inferior to Homo sapiens. However‚ after years and discoveries later‚ scientists and paleontologists have found they are very much like modern human‚ but with different physical appearances. When comparing
