K = Kenyanthropus Platyops “Kenya Man” Discovered by Meave Leaky
K = Kenyanthropus platyops “Kenya Man” Discovered by Meave Leaky and her team in 1998 west of Lake Turkana, Kenya, and described as a new genus dating back to the middle Pliocene, 3.5 MYA. A = Australopithecus africanus STS-5 “Mrs. Ples” The discovery of this skull in 1947 in South Africa of this virtually complete skull gave additional credence to the establishment of early Hominids. Dated at 2.5 MYA. H = Homo habilis KNM-ER 1813 Discovered in 1973 by Kamoya Kimeu in Koobi Fora, Kenya. Even though it is very small, it is considered to be an adult and is dated at 1.9 MYA. E = Homo erectus “Peking Man” Discovered in China in the 1920’s, this is based on the reconstruction by Sawyer and Tattersall of the American Museum of Natural History. Dated at 400-500,000 YA. (2 parts) L = Australopithecus afarensis “Lucy” Discovered by Donald Johanson in 1974 in Ethiopia. Lucy, at 3.2 million years old has been considered the first human. This is now being challenged by the discovery of Kenyanthropus described by Leaky. (2 parts) TC = Australopithecus africanus “Taung child” Discovered in 1924 in Taung, South Africa by M. de Bruyn. Raymond Dart established it as a new genus and species. Dated at 2.3 MYA.

The Modern Man: a Revision of His Definition and a New Estimation of His Emergence Date
9 International Journal of Modern Anthropology Int. J. Mod. Anthrop. 1 : 1-110 (2008) Available online at www.ata.org.tn Original Synthetic Article The modern man: a revision of his definition and a new estimation of his emergence date Hassen Chaabani Hassen Chaabani was born the 07 / 09 / 1947 in Tunis (Tunisia). He is Full Professor and research unit Director at Monastir University. He is the Founder and the President of the Tunisian Association of Anthropology.

Laboratoire de Génétique Humaine et d'Anthropologie, Faculté de Pharmacie, 5000 Monastir, Tunisia. E.mail: [email protected] Abstract - In spite of important anthropological data stored up to date, the recent human evolution is still a subject of great controversy. Here I present a revision of the definition of modern man and an attempt to estimate the date of his emergence. The anatomical feature criterion cannot be considered as a rigorous criterion for identified modern human fossils from those of earlier Homo peoples. This identification could be carried out indirectly from analysis of cultural products and, if possible, directly by ancient DNA analysis. During the last 20,000 years period, Homo peoples have shown a first real cultural progress, which reflects their possession of the superior level of potential intellectual aptitude that marks the definition of modern man. On the basis of this definition, in agreement with several anthropological basic data, I consider that the real modern man, Homo sapiens sapiens, emerged at about 20,000 years ago. -

Early Members of the Genus Homo Bonnie Yoshida-Levine Ph.D., Grossmont College Learning Objectives • Describe how early Pleistocene climate change influenced the evolution of the genus Homo. • Identify the characteristics that define the genus Homo. • Describe the skeletal anatomy of Homo habilis and Homo erectus based on the fossil evidence. • Assess opposing points of view about how early Homo should be classified. Describe what is known about the adaptive strategies of early members of the Homo genus, including tool technologies, diet, migration patterns, and other behavioral trends.The boy was no older than 9 when he perished by the swampy shores of the lake. After death, his slender, long-limbed body sank into the mud of the lake shallows. His bones fossilized and lay undisturbed for 1.5 million years. In the 1980s, fossil hunter Kimoya Kimeu, working on the western shore of Lake Turkana, Kenya, glimpsed a dark colored piece of bone eroding in a hillside. This small skull fragment led to the discovery of what is arguably the world’s most complete early hominin fossil—a youth identified as a member of the species Homo erectus. Now known as Nariokotome Boy, after the nearby lake village, the skeleton has provided a wealth of information about the early evolution of our own genus, Homo (see Figure 10.1). -
The Dates of the Discovery of the First Peking Man Fossil Teeth
The Dates of the Discovery of the First Peking Man Fossil Teeth Qian WANG,LiSUN, and Jan Ove R. EBBESTAD ABSTRACT Four teeth of Peking Man from Zhoukoudian, excavated by Otto Zdansky in 1921 and 1923 and currently housed in the Museum of Evolution at Uppsala University, are among the most treasured finds in palaeoanthropology, not only because of their scientific value but also for their important historical and cultural significance. It is generally acknowledged that the first fossil evidence of Peking Man was two teeth unearthed by Zdansky during his excavations at Zhoukoudian in 1921 and 1923. However, the exact dates and details of their collection and identification have been documented inconsistently in the literature. We reexamine this matter and find that, due to incompleteness and ambiguity of early documentation of the discovery of the first Peking Man teeth, the facts surrounding their collection and identification remain uncertain. Had Zdansky documented and revealed his findings on the earliest occasion, the early history of Zhoukoudian and discoveries of first Peking Man fossils would have been more precisely known and the development of the field of palaeoanthropology in early twentieth century China would have been different. KEYWORDS: Peking Man, Zhoukoudian, tooth, Uppsala University. INTRODUCTION FOUR FOSSIL TEETH IDENTIFIED AS COMING FROM PEKING MAN were excavated by palaeontologist Otto Zdansky in 1921 and 1923 from Zhoukoudian deposits. They have been housed in the Museum of Evolution at Uppsala University in Sweden ever since. These four teeth are among the most treasured finds in palaeoanthropology, not only because of their scientific value but also for their historical and cultural significance. -

Prin- cipal cranial shape differences between H. floresiensis and Homo sapiens are also explored metrically. Keywords: The LB1 specimen exhibits a marked reductive trend in its facial skeleton, which is comparable to the LB1/1 H. sapiens condition and is probably associated with reduced masticatory stresses. However, LB1 is Homo erectus craniometrically different from H. sapiens showing an extremely small overall cranial size, and the Homo habilis Cranium combination of a primitive low and anteriorly narrow vault shape, a relatively prognathic face, a rounded Face oval foramen that is greatly separated anteriorly from the carotid canal/jugular foramen, and a unique, tall orbital shape. -

PALEOANTHROPOLOGY SOCIETY MEETING ABSTRACTS, ST. LOUIS, MO, 13-14 APRIL 2010 New Data on the Transition from the Gravettian to the Solutrean in Portuguese Estremadura Francisco Almeida , DIED DEPA, Igespar, IP, PORTUGAL Henrique Matias, Department of Geology, Faculdade de Ciências da Universidade de Lisboa, PORTUGAL Rui Carvalho, Department of Geology, Faculdade de Ciências da Universidade de Lisboa, PORTUGAL Telmo Pereira, FCHS - Departamento de História, Arqueologia e Património, Universidade do Algarve, PORTUGAL Adelaide Pinto, Crivarque. Lda., PORTUGAL From an anthropological perspective, the passage from the Gravettian to the Solutrean is one of the most interesting transition peri- ods in Old World Prehistory. Between 22 kyr BP and 21 kyr BP, during the beginning stages of the Last Glacial Maximum, Iberia and Southwest France witness a process of substitution of a Pan-European Technocomplex—the Gravettian—to one of the first examples of regionalism by Anatomically Modern Humans in the European continent—the Solutrean. While the question of the origins of the Solutrean is almost as old as its first definition, the process under which it substituted the Gravettian started to be readdressed, both in Portugal and in France, after the mid 1990’s. Two chronological models for the transition have been advanced, but until very recently the lack of new archaeological contexts of the period, and the fact that the many of the sequences have been drastically affected by post depositional disturbances during the Lascaux event, prevented their systematic evaluation. Between 2007 and 2009, and in the scope of mitigation projects, archaeological fieldwork has been carried in three open air sites—Terra do Manuel (Rio Maior), Portela 2 (Leiria), and Calvaria 2 (Porto de Mós) whose stratigraphic sequences date precisely to the beginning stages of the LGM. -

Southeast Asian and Australian Paleoanthropology: a Review of the Last Century
JASs Invited Reviews Journal of Anthropological Sciences Vol. 87 (2009), pp. 7-31 Southeast Asian and Australian paleoanthropology: a review of the last century Arthur C. Durband Department of Sociology, Anthropology, and Social Work, Texas Tech University, MS 41012 Holden Hall 158, Lubbock, TX 79409-1012, USA e-mail: [email protected] Summary - A large and diverse body of scholarship has been developed around the fossil evidence discovered in Southeast Asia and Australia. However, despite its importance to many diff erent aspects of paleoanthropological research, Australasia has often received signifi cantly less attention than it deserves. is review will focus primarily on the evidence for the origins of modern humans from this region. Workers like Franz Weidenreich identifi ed characteristics in the earliest inhabitants of Java that bore some resemblance to features found in modern indigenous Australians. More recent work by numerous scholars have built upon those initial observations, and have contributed to the perception that the fossil record of Australasia provides one of the better examples of regional continuity in the human fossil record. Other scholars disagree, instead fi nding evidence for discontinuity between these earliest Indonesians and modern Australian groups. ese authorities cite support for an alternative hypothesis of extinction of the ancient Javan populations and their subsequent replacement by more recently arrived groups of modern humans. Presently, the bulk of the evidence supports this latter model. A dearth of credible regional characteristics linking the Pleistocene fossils from Java to early Australians, combined with a series of features indicating discontinuity between those same groups, indicate that the populations represented by the fossils from Sangiran and Ngandong went extinct without contributing genes to modern Australians. -

Etler Newly discoveredfossil hominidsfrom the late middle Pleistocene ofChina demonstrate that archaic forms of Homo sapiens were either coexistent with or slightly more recent than advancedforms of Homo erectus. This is most clearly seen at sites in Hexian and Chaoxian counties, Anhui province, which date to between 150-200,000 YBP by uranium series tests. The replacement of H. erectus by archaic H. sapiens in China is characterized by the retention of a significant component of heritage features in archaic H. sapiens, overlaid by a mosaic of changes in craniofacial anatomy that trend towards modern humans. This new evidence givespowerful support to the regional continuity theory of human evolution in eastAsia. Furthermore, it suggests that the transitionfrom H. erectus to archaic H. sapiens in China was relatively quick andpossibly modulated by a heightening ofgeneflow between western and eastern Asia at approximately 250,000 YBP.
