The Evolution Of Homo Erectus: Comparative Anatomical Studies Of An Extinct Human Species by G. Philip Rightmire

May not contain Access Codes or Supplements. Along with Middle Stone Age artifacts, animal bones, and other food waste, there are hominin cranial fragments, mandibles with teeth, and a few postcranial remains. However, the systematic position of these hominins remains controversial. It additionally files the heritage of this extinct human species and indicates a path wherein Homo erectus could have given upward thrust to humans extra like Homo sapiens. The Mauer mandible, holotype of Homo heidelbergensis, was found in 1907 in fluvial sands deposited by the Neckar River 10 km southeast of Heidelberg, Germany. Homo erectus seems to have evolved in Africa before spreading to other regions of the Old World. Other discrete characters and measurements suggest that the Dmanisi skulls are best placed with H.

Nevertheless, the evidence from anatomical analysis and measurements supports the hypothesis that Dmanisi is close to the stem from which H. In 1997, Bermúdez de Castro and col- leagues defined a new species, Homo an- tecessor Bermúdez de Castro et al. Faces are massively built with strong supraorbital tori, frontals are flattened, and vaults remain low with less parietal expansion than in Homo sapiens. The first discoveries of Homo erectus were made in Java late in the 19th century. Other Middle Pleistocene crania differ from those of Homo erectus.

Because of damage, the temporal lines are indistinct. Perhaps the most critical problem has been an incomplete understanding of variation in skull form. Brand new book, sourced directly from publisher. This occurred over a long period of time, during which the populations changed relatively little. American Journal of Physical Anthropology. The front teeth of H. It is generally accepted that modern humans evolved in Africa.

On the right side, where the surface is too weathered to show much detail, there is a palpable bulge filling the parietal angle just above asterion. The convex clivus and receding symphysis of skull 5 produce a muzzle-like form similar to that of Australopithecus afarensis. Pieces of another thin-walled cranium along with upper and lower jaws and came to light in 1963. Rightmire has studied the major artifacts and provides a rigorous overview of each, including sketches, dimensions, various views, discussion and analysis. Toward the back, in the few remaining pages, Rightmire shares trends in brain size for the species and summarizes his analyses in two pages. The claim for two taxa is evaluated here with special reference to the facial skeleton.

On Page 6, he includes two tables that inventory the body parts of samples found in the principal Indonesian and Chinese localities, as well as Africa northwest, east and south. Thus, the earliest known hominins to have lived outside of Africa in the temperate zones of Eurasia did not yet display the full set of derived skeletal features. Analysis of Olduvai animal fossils also shows that some marks were made by either rodent or carnivore teeth, the indication being that at least some of the animals were killed by nonhominin predators. Discoveries from the Turkana basin and other localities in sub-Saharan Africa; 5. Newly discovered Homo remains, stone artifacts, and animal fossils from Dmanisi, Republic of Georgia, provide a basis for better understanding patterns of hominin evolution and behavior in Eurasia ca. It is apparent that Broken Hill is similar to other African crania from Bodo , Ndutu, and Elandsfontein as well as European fossils including Arago and Petralona.

Recently, issues of life history and the timing of development have been raised as well. These fossils, however, are not associated with any teeth or skulls, and it is probably not appropriate to use them as the basis for describing early Homo. These characters distinguish early Homo from species of Australopithecus and Paranthropus. Dating the fossils Several approaches have been used to date H. Other issues are phylogenetic, and it is important to clarify the relationship of Homo heidelbergensis to Neanderthals and recent humans.

Philip Rightmire is a scholarly discussion of Homo Erectus' evolution through time, across the planet, through his diverse global locations--China, Africa, Indonesia, Spain, Europe, including Trinil, Sangiran, Zhoukoudian, Ternifine, Sale, Turkana, Olduvai Gorge. What happened earlier is less clear, because fewer bones have been available for study. At or before the beginning of the Middle Pleistocene, new populations spread through western Eurasia and perhaps also to the Far East. There are still questions about the timing of these dispersals and the extent to which modern people replaced or exchanged genes with other, more archaic groups, but new problems are now coming more clearly into focus. Studies of the variation within H.

At or before the beginning of the Middle Pleistocene, these new populations spread across Africa and into western Eurasia. Dated at close to two million years ago, this specimen is classified by some paleoanthropologists as Homo rudolfensis. Comparisons with the Buia— Danakil skull Abbate et al. Encephalization quotient values confirm this finding. Relative variation at Dmanisi is comparable to that in selected reference groups.

From United Kingdom to U. The first confirmed remains found at Olduvai consist of several teeth and a lower associated with fragments of a cranium and some hand. A similar approach is used with the Middle Pleistocene sample. All of the mandibles possess marginal tubercles, mandibular tori, and a distinctive patterning of mental foramina. Other fossils have proved less easy to assign to H. Supraorbital tori and other vault superstructures are only moderately developed.

Interactions of the brain and cranium in archaic populations remain poorly understood. This book provides a wealth of information about individual crania, jaws and postcranial remains and will serve as an important guide to the anatomy of Homo erectus. This finding is generally in keeping with observations made on other parts of the cranium, lower jaw, and teeth. This occurred over a long period of time, during which the populations changed relatively little. It is the belief of some anatomists that endocranial casts of H. The preponderance of evidence supports our null hypothesis.
