"Evolution of the genus homo"

Download file to see previous pages The Australopithecines were the earliest known bipedal hominid species descending from the apes, the latter using all four limbs for locomotion, like the other animal species’ of today. The Australopithecines were anatomically more related to the extant apes in terms of brain size, possessed large postcanine teeth and employed mixed climbing with bipedalism for locomotion (Wood, 1992). The Homo habilis species has been supposed to succeed the Australopithecines in the evolutionary ladder followed by Homo erectus and the Homo sapiens (Wood, 1992). Fossil discovery and characterization has created some debate about the existence of the Homo habilis species as an intermediate species between the Australopithecines and the Homo erectus, but there is a consensus that the Homo erectus was the most primitive of the species from which the present day humans evolved. There are two distinct and contrasting views for the evolutionary ladder which the modern day Homo sapiens followed. The first suggests that the present day populations were derived as a result of in situ evolution from the Homo erectus species which was dispersed worldwide from the East African continent during the Lower Pleistocene (Finlayson, 2005). According to the other viewpoint, all present day populations of human species are the descended from a recent common ancestor who lived in East Africa 150,000 years ago and these descendants have replaced all regional populations, if they ever existed (Finlayson, 2005). The latter view is now accepted and has been labeled as the ‘Out-of-Africa-2’ viewpoint. According to its claims, the biologically superior humans that persist till now replaced all other homo species’ and their geographical spread was driven by climatic and ecological factors (Finlayson, 2005). The recent discovery of a hominid species in Indonesia, which has been given the nomenclature Homo floresiensis, whose existence is under active debate has confounded many anthropologists with one opinion suggesting that the species may have evolved from an early migration of the Homo erectus which was dwarfed due to peculiar ecological factors in the region (Finlayson, 2005). The features which characterized the evolution of the Homo species to the present generation of humans are a larger relative brain size, larger body, a slower rate of growth and maturation of the body, bipedal mode of locomotion and smaller teeth and jaws facilitating lesser masticator effort as compared to the primitive species of Australopithecines and Paranthropines (Aiello & Wells, 2002). Historically, the migration of the Homo erectus occurred from Africa to the Eurasian and Asian continents from which the genus spread to all geographical regions of the world. The species evolved into the primitive ‘Neanderthal’ man which was very similar to modern humans except for the larger body size and an extremely protruding mid facial anatomy (Web, undated). The Neanderthal man can be traced to 250,00 years ago which is a relatively short period as compared to the overall time span associated with the evolution of the genus. The discovery and employment of stones, sticks as primitive tools was a cultural revolution which was not confined to the latter species as some evidence of their use in the Pliocene and the Pleistocene eras by the Australopithecines and Paranthropines also exists.

Tools And Time: The Evolution Of Technology In The Genus Homo
...? Tools and time: The Evolution of Technology in the Genus Homo Human evolution is a complex and puzzling process that many scholars have dedicated their efforts to unravel. The transformation of animals to human is a puzzling issue that attracts attention of the scientists to study systematic development of brains in genus Homo. Scientists suggest that the modern man developed from simple forms of life. Scientists reveal that that Homo sapiens emerged from the ape-like creatures that existed in some parts of the world. The scientists believe that the apes and Homo sapiens belong to same ancestor. Other...

...?Evolution Evolution can be defined as the modification of living organisms through time as they descend from their ancestors, generation after generation. The ancestors of various species look different in their structure, behavior and physiology back in time. Prior to Darwin, though some naturalists had speculated about modification of species, they failed to explain why and how species change. They also believed that evolution began with special creation of only a fixed number of species. Partially influenced by Thomas Malthus' essay on the Principle of Population and stimulated by a letter from Alfred Russell Wallace, Charles Darwin in 1859 discussed the evolution of species through natural selection in his famous work titled... ., 2012,...

Homo Sexual- Rogerian Argument
...? 22 March Adoption of children by homosexual couples: Introduction: Homosexuality is a wrongful and unnatural way of living. It causes a lot of troubles in the society. It does not only ruin the life style of those who practice it, but also, peace in the life of those who are related to them is at stake. Like all other matters of life, homosexuals should not be allowed to adopt children. Adoption of children is a very complicated matter, which requires consideration of several aspects. Adoption of children by homosexual couples is extremely harmful for their psychological and physiological development. Critic’s view: In the paper written by (Smith), child adoption by homosexual couples has been favored. (Smith) has made... 22 March Adoption...

Neandertals and Homo Sapiens
...?Neanderthal Long ago have people been bewildered by the thought of evolution, what seems to be a natural process for some proved to be a strange andawkward process for others, and still to this day, the theory of the human evolution presents a set of questions that to this day remain unanswered, one of those questions being the question of the extinction of the Neanderthal man, another would be the degree of relationship between the Neanderthal and the modern human and if the two species are related at all. So what kind of sub human species is this Neanderthal and can we even qualify it of human let alone sub human. The Neanderthal question has loomed to be a very controversial one all throughout the...

...?Naked Mole Rats- Genus Heterocephalus glaber Known taxonomically as Heterocephalus glaber, belonging to genus Heterocephalus and group Rodentia of family Bathyergidae, naked mole rats are generally found in the hot, semiarid regions of Africa. They usually live in large colonies present underground in subterranean tunnels (Ciszek), where on average 75 mole rats live in each colony. This paper describes features of naked mole rats, with main focus on their eusociality. Only one female mole-rat reproduces by breeding with a few males of the community; while, the rest of the males and females form the labor force which perform tasks like maintenance of colonies, nest building, transportation of soil, and...

Evolution of lactase gene in homo sapiens
...that a favourable trait mutated. Additionally, one must show that the trait was transmittable to offspring and the environment favoured that trait. This may necessitate genital analysis of pre-historical data as well as present ones. Furthermore, these patterns ought to be analysed in relation to the behavioural or cultural patterns of the subjects as it could affect the adoption of the trait. The paper will look into these dimensions in order to illustrate the evolution of the lactase gene. Advantages and disadvantages in a population Lactase-phlorizin hydrolase (LPH) is the enzyme responsible for the digestion of lactose in Homo sapiens. Lactase activity in the intestines depends on the maturity of the...

...Evolution British novelist Arthur Koestler once quipped that the human brain is, " the only example of evolution providing a species with an organ which it does not know how to use". Indeed, the human brain, and its capacity for imagination and abstract thought, has made the topic of evolution one of the most debated and controversial issues of our time. Lines are often drawn along religious beliefs that reject the theory of evolution, while other camps argue that the theory is fact. Evolution is often misunderstood and has challenged scientists to provide proof for the belief that all life transforms, progresses, and adapts to its environment. The...

...Running Head: Evolution Evolution [Institute’s Evolution Since centuries, evolution has remained a significant issue in the human societies that continued to question people with the inquiries such as how humans get into this world, how humans came into existence, etc until today. In the result, a huge number of researchers, scholars, philosophers, etc have endeavored for many years to propose their explanations regarding such curiosity of humans. In specific, different theories exist in the case of evolution; however, theistic evolution is one of the theories that have been able to influence people. It indicates that the universe exists since more than ten billion years, whereas the crust is only four billion years old. Moreover... , such...

...; as such, phylogenetic hypothesis on human evolution cannot be relied (Coyne, 2009). Also, the time gap existing between Australopithecus afarensis and Homo erectus leaves a lot to be desired. Following a short time that creates the difference between the two species; one wonders just how evolutionary mechanism could work so fast to accomplish the change from Australopithecus afarensis to Homo erectus (Coyne, 2009). In my view, such a change could not be possible within such a short span of time. Chapter 9: Evolution Redux In this chapter, the author tries to psychoanalyse the critics of evolution saying the reason behind their scepticism emanates from...
