First the Homo sapien will be insert the food into its alimentary canal. It will then chew the food creating a bolus of food‚ which is caused by the enzymes in the saliva which break down the food making it ready for swallowing or deglutition. The bolus of food goes through the larynx‚ which is the hollow muscular organ forming an air passage to the lungs and holding the vocal cords in humans and other mammals. The bolus of food passes through the oesophagus. The oesophagus is a muscular tube which

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

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

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
