Download file to see previous pages These reductions in molar size have led to the present man having small molars. According to the researchers, they make the conclusion that the changes are in line with the starting of fire use and eating cooked food instead of raw food (Organ, Nunn, Machanda and Wrangham 14559). The article findings and explanations are in line with the discussions made by Stanford in his book Exploring biological anthropology: the essentials where the discussion on hominids is based mainly on their anatomical changes and their significance during that time in the phylogeny of the hominids from Australopithecus to Homo sapiens. Stanford specifically discusses the anatomical changes and how the body bipedal plans of the earlier hominids are how they were adapted to the environment (Stanford, Allen and Anton 239). The same discussion is made later on in the book but this time the focus is on the genus Homo (Homo erectus, Homo neanderthalensis and Homo sapiens) and how they were more evolved towards becoming more like the present humans (Stanford, Allen and Anton 277). Even though both chapters discuss different hominids, the anatomical changes according to the period in history and the environment all add up and present a detailed and flowing phylogeny of these hominids. The same discussion about anatomical structures of the various hominids and how each structure of the body acted to facilitate the survival of the different hominids are made in the book by Bailey and Hublin. The book has detailed explanations of the different body structures which give more details and more structures compared to the article discussion and the book by Stanford. However, they all finally discuss the same issue and give the same enlightening discussion. There are also explanations of the effects of the different changes that took place in the body structures of the hominids and the effects of that to not only the hominids but also to the present human being.  ...Download file to see next pagesRead More

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
...deterring the chances or rather the likeliness of establishing a sound answer to all these questions. What follows is a brief presentation that sheds the light on this species of human like creature, exposing the different anthropological breakthroughs and discoveries that have came to remold our idea of the Neanderthal man. Modern anthropological findings suggest that the Neanderthal man may have lived around the years extending from 250 000 to 20 000 BC. Counting for more than a century since its discovery, theories and hypotheses around this creature have diversified albeit they mostly reflected the prejudgments of the moment. Long considered as a sub-human species at the heart of the “Homo Sapien” lineage it was at...

Evolution of the genus homo
...? 28 May Evolution of the Genus Homo Life has evolved on Planet Earth over millions of years in a wonderful process of selection and favor for particular genera and species and the Genus Homo is no exception. As the human species, the most intelligent form of the animal kingdom belongs to this genus; it has been studied and researched extensively in order to satisfy human curiosity. The widely held view is that the genus originated in East Africa sometime in-between 5-10 million years ago and evolved from the Australopithecines of the primitive world (Web, undated). The Australopithecines were the earliest known bipedal hominid species descending from the apes, the latter using all four...

Australopithecus Sediba: The Early Homo Species
... Australopithecus sediba- The Early Homo Species The discovery of the two partial skeletons of a hitherto unclassified species of hominid, called Australopithecus sediba from a cave at Malapa site in South Africa is a unique find in the sense that it extends much missing information as to the physical evolution of Homo sapiens. As the primary focus of Physical Anthropology is to trace and explain the development and ancestry of Homo species in context to other primates, the research under consideration is of immense relevance to this discipline. This recently documented species besides being an...

Phylogeny Research Paper
... Why are the Porifera now considered a clade and not a Phylum? Describe the phylogenetic status of that group of organisms that is best supported by current evidence and show how sponges may be related to protozoans and to the other metazoans. Until recently, Porifera had been considered a phylum but new evidence suggests that it is a clade. A clade represents organisms that have a common ancestor and members of the clade may both be extant or extinct. This is much larger than the limiting phylum under which Porifera was thought to belong. According to recent studies involving molecular analysis of 18S rRNA/DNA, paraphyly was evident in Porifera. It showed that Calcarea (calcareous sponges) appear to have closer affinities... Why are the...

Discussion Of The Article About The Australopithecus the article do you think is the most likely ancestor to the genus of Homo? Why? Please use specific evidence in your response. Australopithecus africanus seems to be the closet ancestor or relative to the Homo genus. It had unique features that were less primitive than A. afarensis. It had a flat face, evidence of stronger chewing force, a bigger jaw, and great sexual dimorphism, which meant the males and females looked very different and had different sizes and weights. Their skeletal architecture suggests shifts related to environmental and dietary forces. (McHenry 2009) 3. In what ways is Paranthropus anatomically different from australopithecines? What are the three species...

Does ontogeny recapitulate phylogeny
...Does Ontogeny Recapitulate Phylogeny? Before we can discuss the question “does ontogeny recapitulate phylogeny?”, we must first understand the two differing theories that comprise that query. What exactly is Ontogeny? How is it similar to Phylogeny? What makes the two theories of development different from one another? This paper serves to explain the difference between the two theories aside from attempting to explain that the Ontology Recapitulate Phylogeny (ORP Theory) is false through direct explanations from various authoritative sources. To begin, allow me to define the theory behind Ontogeny. Ontogeny is the scientific belief pertaining to the development of...

Systematics and Reconstructing Phylogeny
...4 April Systematics and Reconstructing Phylogeny Systematics is the scientific study of how organisms are diverse along with their evolutionary relationships and origin. After scientific studying of organisms is done, taxonomy is used to classify, name and describe organisms. Classification is the gouping of the organisms by their similarities. The reason why it is done is to reveal their historical relationships, to avail universally recognized names of the organisms by using one language which ensures consistency. Binomial nomenclature is a two name naming system used to scientifically name organisms. The first name is usually the genus name and the second name is usually the specific name. Species are classified into...

They also appear to strongly believe in the “Evolution Theory,” while a significant percentage of the population strongly opposes it. Media on the other hand is neutral and it reports the findings without any bias. The articles analyzed are: Berger, L. R., de Ruiter, D. J., Churchill, S. E., Schmid, P., Carlson, K. J., Dirks, P.

...bone at behind the skull. This made the classification of this species difficult. Another cranium fossil which was discovered in Sanscombe, England was in 3 pieces but was missing the face although its cranium resembles the Steinheim skull. This also brings a controversy on the classification of the fossil as Homo heidelbergensis. There have been different views whether the Homo heidelbergensis should be separated into two different taxa due to the questions about its make-up. Some specialist explains that the specimens from the Europe and Africa should be set apart to represent the distinct lineages. Supporters of this view hold that fossils from Germany, Greek, and French share many features with the...
