Homo habilis

paleoanthropology. Current research aids in the modification of the human ancestral tree and the analysis of various sites. One of the newest sites dealing with human evolution is the Rising Star cave system in South Africa, where a new species of human ancestors, Homo naledi, was discovered. Because of its modernity, quick excavation, and controversial conclusions, the site of the Rising Star cave system is still being actively researched. The remains have yet to be dated and this information…

This theory suggests that there were two colonisations of the world, the first being approximately 100,000 years ago when Homo erectus first migrated out of Africa and evolved separately creating three major species in different areas of the world, Homo sapiens, erectus and neanderthalensis. It is then thought the group of Homo erectus still located in Africa evolved into Homo sapiens and began the second colonisation where they began replacing the other species possibly due to ‘survival of the…

Dawkins says that people should believe in the theory of evolution without any proof. Since there are an existence of fossils, there are a certified tested proof of evolution. Fossil evidence of whales and turtles are talked about in this chapter. Dawkins does discuss in small detail the questionable crocoduck. Evolution clearly does not only rely on fossils. The process of a fossil is quite interesting though. The first step is for the creature to fall into a body of water. In the water it must…

culture tools were made. The first tool that was made was the Oldowan dating back to 2.5 - 1.2 million years ago. The homo habilis constructed this tool by using stone and beating off flakes of the stone. There were two types: flake tool and core tool, depending on what needed to be done. The second tool made was the Acheulean it dates back to 1.6 million - 200,000 years ago. The homo erectus produced these tools. The main acheulean tool is the handaxe, varying in size. These tools were used…

thirteen million years ago. Various forms of species have been documented over all those years with transitions including; Australopithecus afarensis dated 3.2 million years ago, the Homo species dated about 2.8 million years ago (Drake, 2015). The Homo species which was inclusive of Homo erectus, Homo habilis and Homo sapiens. Evidence of evolution from my research is highly attributed to genetic evidence with 98.8 percentages in DNA similarity though there are missing links on where the apes…

Since the emergence of the genus Homo, the hominins went through great patterns of evolution over generations. Through series of adaptations, the genus Homo spread in various geographic locations and eventually emerged as anatomically modern humans. With the allele frequency changes that evolved in the genus Homo, there is key evidence that microevolution led to macroevolution. From speciation to extinction, the modern synthesis helps us explain not only the mechanisms of evolution and the…

Until 11,700 years ago our earth had been in the Pleistocene Epoch, incorporating an evolutionary surge that lead to Homo Habilis, who lived from about 2.1 to 1.5 million years ago(2). By the peak of this duration the global temperatures on earth dropped by about 5oC, plunging the entire planet into an ice age, creating vast glaciers miles deep that expanded across limitless amounts of land, locking hordes of water into impenetrable sheets of ice. However, this gave a few species on earth a…

The first mammals evolved from mammal-like reptiles at the end of the triassic period. Therapsids, or mammal-like reptiles, is an order of reptiles that lived in the Permian and Triassic Periods before going extinct in the mid Jurassic Period. It is difficult for scientist to determine when the divide between therapsids and mammals occurred. Early mammals had small, mouselike forms. Very few were large, because dinosaurs were the unquestioned dominant land animals on earth. The ecological niche…

primarily speaks about the views that researcher Richard Wrangham has on the stimulation of human evolution, specifically the significance of cooking upon evolution. Mr.Wrangham states that the practice of cooking our food, beginning with our ancestors the Homo erectus, led to our evolution as a species and enabled us to cultivate more nutrients/energy from the food that we ate. This in turn led to our species having more energy to expend on their growth, allowing for stronger muscles, healthier…

Humans, animals, plants and all kinds of creatures live in this planet relevant to each other in an established order. To maintain the order and to keep the planet habitable we are responsible for our actions against other creatures. This leads to the point that we have some moral obligations towards animals. To clarify, we as humans can not cause unnecessary pain that even Edwin Locke who is against animal rights agrees upon (Edwin Locke, 1). However, these moral obligations do not include meat…
