Genus Homo Evolution

The article I have chosen was written by Helen Pilcher and is about evolution of creatures, especially for primates. However, until now, what do our very first primates were like still remain mysterious as we do not have sufficient information and evidences which are 60 million years ago. Yet, we still cannot deny that evolution occurs in creatures. No matter for humans, animals or plants, all of them will make changes because of their living habits and environment in order to survive. In this article, the author explains everything clearly about the primate evolution was taken around million years ago and ancestors are a small and nocturnal creature.

We measured the skulls of the fossil hominins: Australopithecus, Homo habilis, Homo erectus, and Neanderthal. We measured the length, height, width and orbit height of their skulls to calculate the estimated brain size and estimated body mass. Hypothesis 1. For Life History, humans will reproduce earlier than the primates and apes because of their body mass.

Ancestors in Our Genome, addresses the continuingly advancing disagreement upon whom our closest ancestor is within the great apes, described as the hominoid trichotomy debate. The author, Eugene E. Harris examines many different sources of evidence within the book, and with the help of improvements in biological and DNA technology he helps discover who our closest ancestors were. Also when we were first separated from them and how the separation took place. Although there have been many recent advances in technology, a large number of unanswered questions are still a mystery within our genome and evolution from the great apes. Chapter one discusses the debate of morphology - studying fossil evidence of the great apes - versus molecular

The theories of early primate evolution are Arboreal, visual predation, angiosperm hypothesis. The Arboreal theory explains primates unique traits in adaption in trees while visual predation details the

These new environments made possible the evolution of nonhuman primates, and influenced the evolutionary path of primates. Three common theories of early primate evolution are the Arboreal Hypothesis, the Visual Predation

Climate change influenced nonhuman primate evolution by forcing the evolution of species and creating new environments that allowed for primates to live. "A rapid temperature increase around 55 mya ... led to an expansion of evergreen tropical forests, the environment that made possible many mammalian groups, including primates." (pg. 260). As rapid temperature increase created new environments a rapid cooling in the beginning of the Oligocene limited the range of habitats greatly. Due to this reduction a majority of the primates during this time lived around the fayum region in northeast Africa.

Hence, this source should be trustable. About 2,300,000 years ago, there existed a kind of primate began to use tool. They lived together, and they knew how to corporate with each others to hunt foods with the

al., 1988; Binford, 1978). For example Binford (1978) made comprehensive observations of butchery activities by the Nunamiut Eskimos and then studied the bones for resulting butchery damage. Results from Binford’s (1978) study provided information for an account of butchery activities and their associated cut marks. Such marks may be used as models of early hominids butchering patterns and hence, provide evidence for meat eating by early hominids (Binford, 1978; Binford, 1981; Nilssen, 2000).

One of the first known human ancestors to be recorded, Australopithecus afarensis, is the main focus of BBC’ Prehistoric Autopsy finale. The show attempts to recreate the structure of a particular set of remains named Lucy. Lucy’s skeleton bears many similar physical characteristics to modern-day humans. Lucy’s remains present the question of why our ancestors left the safety of the trees, the first evidence of bipedalism in primates, and the cost of evolving towards bipedalism on the body. Before watching the episode, I wrote some possible answers to why our ancestors left the trees, coming to multiple conclusions, such as being able to fight off the predators of the ground, innovations of tools, loss of nutrients in their tree lifestyle,

Our closest extinct cousins were proliferated in the science community as in superior beings who were primitive in nature, had no intellectual thought, art, culture, or language. Recently, archaeologists, palaeontologists, scientists, and anthropologists are re-examining the evidence and finding new clues that could help resolve the ongoing bitter disputes about Neandertals. Concealed deep in our

When Eugene DuBois found the first specimen of the Java Man, he was instantly convinced that he had discovered the missing piece of the puzzle of human evolution. The Java Man was the perfect linkage between man and ape thus earning the name Pithecanthropus erectus, or the upright walking chimp (Carroll 92). His findings of a skull cap, thigh, and molar all found within the same area at Trinil suggested that his finding was the perfect intermediate. The skull cap had a braincase capacity of only 1,000 cc, shorter than that of a human, but significantly larger than that of an ape. All of DuBois’s hard work had paid off; however, his critics were far from satisfied.

Evolutionists believe that man originated from apes which pertains to the natural selection while creationists believe that man was created in God’s image by God. Evolutionists say that scientific evidence shows that the physical and behavioral traits of humans originated from apelike ancestors and evolved over a period of around 6 million years. The ability to walk on two legs evolved over 4 million years ago. Other human characteristics like a large and complex brain, the ability to make tools, and the capacity for language developed recently. Physical and genetic similarities show that the human species, homo sapiens, has a very close relationship to another group of primate species, apes.

The bipedal movement is another way to say standing upright, on two feet, hence bi-ped. The evolutionary benefits of bipedalism begin with being higher off the ground which gives

Anthropologist, archeologist, and other scientist believe that Homo sapiens originated from Africa about 200,000 years ago and migrated out of Africa about 100,000 year ago based on the findings of three sets of human fossils (p. 3). This is known as the “Out of Africa”

(Own knowledge, Source D) Bipedalism is unique to humans and it is known to be one of the earliest developments in hominids. (Source G, C) This phenomenon has intrigued researchers and historians for a number of years. There are many answers to this involved question; this essay will look at a few of them.
