Homo economicus

more about our past ancestors with the intent to reveal more about ourselves and to define what innately makes us human. Although many skeletons and species of Homo have been identified, we have not yet discovered our last common ancestor, and this has been a hot topic of debate. The genus Homo is bookended by Australopithecus afarensis and Homo erectus, the former more ape than human, while the latter was responsible for making stone tools. However as National Geographic claims, “there is still…

evolution is a lengthy process of change occurring for millions of years. Modern humans, also known as Homo sapiens, are the only surviving species of the genus Homo. Three important ancestors that share close relationships and characteristics with Homo sapiens are Homo habilis, Homo erectus, and Homo Neanderthalensis. To begin, Homo habilis is the first member of the genus Homo. During the time of Homo erectus, the species began to exhibit more similar features to humans…

ones are the influence of food on inter-birth interval, the avoidance of starvation by Homo sapiens ancestors, our ancestors’ loss of body hair, and the influence of Darwinian selection for social tolerance and cooperation. Wrangham’s hypothesis provides answers for these and other questions throughout his book. Wrangham opens his book pondering a deep question: what made us human? He then states that the Homo genus “stemmed from the control of fire and the advent…

ardipithecus boisei is 18.5, homo erectus is 35.71, homo habilis is 33.6, homo heidelbergensis is 26.1, homo neanderthalensis is 25.5, homo sapiens is 36.77, and sahelanthropus tchadensis is 18.5. The fact is if the opisthion index is less than 15, then that organism walks with two feet. We can conclude that all the organisms are bipedalism…

The Lebombo Bone is a Baboon Fibula, it is an ancient mathematical artifact. It was used as a Tally Stick and is nearly 35,000 years old. With the Ishango Bone is dating back to 20,000 B.C. it is yet another amazing mathematical artifact. Found in the 1970’s during the excavations of a Border Cave, the bone was found with nearly 29 clear defined notches and with it being found it was stated that it was the oldest mathematical artifact dating it was approximately dated back to 35,000 B.C. Judging…

Introduction – *Infraclass Metatheria includes pouched mammals andwas first proposed by Thomas Henry Huxley (1880) comprising 272 primitive mammals. *Metatherians are an…

Homo Floresiensis We are the homo species that were found about 95,000 to 12,000 years ago on the island of Flores, Indonesia. We are 3 to 6 inches tall being bipedal, having small brains, shrugged-forward shoulders, no chins, diminished forehead and large feet because of short legs. We are also nicknamed as the “Hobbit” after the tiny creatures in the book Lord of Rings. We have been the most spectacular discovery so far being the most extreme human ever discovered. We don’t look like modern…

is the supposed birthplace of the human race. It is here that the Australopithecines, a group of hominins including Australopithecus and Paranthropus, lived from 4.2 to 1.2 million years ago. In the same area but from 1.9 to 0.027 million years ago, Homo ergaster also roamed around. Even though they shared the same geographic location, they each represent very different phases of the evolution to what we are today. It would therefore be interesting to see how they differed, based on the…

similar physical type compared to Neanderthals. The tooth, however has not provided researchers with any new discoveries on its morphological characteristics, other than having similarities to Homo erectus teeth (Reich, Genetic). However the last finding of the toe bone has revealed through extensive testing that Homo sapiens sapiens did in fact interbreed with Denisovans and have hybrid offspring (Zimmer, toe). Finally recent discoveries of skulls found in Dali and Maba may have Denisovan…

ecological conditions and behavioral patterns that contributed to the evolution of Homo habilis, Homo erectus, Archaic Homo sapiens, Neanderthals and early modern Homo sapiens during that period of time. First of all, the Pleistocene Epoch is the main point of this paragraph. The Pleistocene Epoch takes place from 2.6 million to 15,700 years ago. it is considered as the reason of the demise of many…
