Defining the Genus Homo
Defining the Genus Homo Mark Collard and Bernard Wood Contents Introduction ..................................................................................... 2108 Changing Interpretations of Genus Homo ..................................................... 2109 Is Genus Homo a “Good” Genus? ............................................................. 2114 Updating Wood and Collard’s (1999) Review of Genus Homo .............................. 2126 Conclusion ...................................................................................... 2137 Cross-References ............................................................................... 2138 References ...................................................................................... 2138 Abstract The definition of the genus Homo is an important but under-researched topic. In this chapter we show that interpretations of Homo have changed greatly over the last 150 years as a result of the incorporation of new fossil species, the discovery of fossil evidence that changed our perceptions of its component species, and reassessments of the functional capabilities of species previously allocated to Homo. We also show that these changes have been made in an ad hoc fashion. Criteria for recognizing fossil specimens of Homo have been outlined on a M.

Language evolution to revolution: from a slowly developing finite communication system with many words to infinite modern language Andrey Vyshedskiy1,2* 1Boston University, Boston, USA 2ImagiRation LLC, Boston, MA, USA Keywords: Language evolution, hominin evolution, human evolution, recursive language, flexible syntax, human language, syntactic language, modern language, Cognitive revolution, Great Leap Forward, Upper Paleolithic Revolution, Neanderthal language Abstract There is overwhelming archeological and genetic evidence that modern speech apparatus was acquired by hominins by 600,000 years ago. There is also widespread agreement that modern syntactic language arose with behavioral modernity around 100,000 years ago. We attempted to answer two crucial questions: (1) how different was the communication system of hominins before acquisition of modern language and (2) what triggered the acquisition of modern language 100,000 years ago. We conclude that the communication system of hominins prior to 100,000 years ago was finite and not- recursive. It may have had thousands of words but was lacking flexible syntax, spatial prepositions, verb tenses, and other features that enable modern human language to communicate an infinite number of ideas. We argue that a synergistic confluence of a genetic mutation that dramatically slowed down the prefrontal cortex (PFC) development in monozygotic twins and their spontaneous invention of spatial prepositions 100,000 years ago resulted in acquisition of PFC-driven constructive imagination (mental synthesis) and converted the finite communication system of their ancestors into infinite modern language. -

This, the thinking went, was replaced by the taller, larger-brained Homo erectus from Asia, which spread to Europe and evolved into Nean derthals, which evolved into Homo sapiens. But what lay between the australopiths and H. erectus, the first known human? BETTING ON AFRICA Until the 1960s, H. erectus had been found only in Asia. But when primitive stone-chop LIBRARY PICTURE EVANS MUSEUM/MARY HISTORY NATURAL ping tools were uncovered at Olduvai Gorge in Tanzania, Leakey became convinced that this is where he would find the earliest stone- tool makers, who he assumed would belong to our genus. Maybe, like the australopiths, our human ancestors also originated in Africa. In 1931, Leakey began intensive prospect ing and excavation at Olduvai Gorge, 33 years before he announced the new human species. Now tourists travel to Olduvai on paved roads in air-conditioned buses; in the 1930s in the rainy season, the journey from Nairobi could take weeks. The ravines at Olduvai offered unparalleled access to ancient strata, but field work was no picnic in the park. Water was often scarce. Leakey and his team had to learn to share Olduvai with all of the wild animals that lived there, lions included. -

Homo Erectus Infancy and Childhood the Turning Point in the Evolution of Behavioral Development in Hominids
10 Homo erectus Infancy and Childhood The Turning Point in the Evolution of Behavioral Development in Hominids Sue Taylor Parker In man, attachment is mediated by several different sorts of behaviour of which the most obvious are crying and calling, babbling and smiling, clinging, non-nutritional sucking, and locomotion as used in approach, following and seeking. —John Bowlby, Attachment The evolution of hominid behavioral ontogeny can be recon - structed using two lines of evidence: first, comparative neontological data on the behavior and development of living hominoid species (humans and the great apes), and second, comparative paleontolog- ical and archaeological evidence associated with fossil hominids. (Although behavior rarely fossilizes, it can leave significant traces.) 1 In this chapter I focus on paleontological and neontological evi - dence relevant to modeling the evolution of the following hominid adaptations: (1) bipedal locomotion and stance; (2) tool use and tool making; (3) subsistence patterns; (4) growth and development and other life history patterns; (5) childbirth; (6) childhood and child care; and (7) cognition and cognitive development. In each case I present a cladistic model for the origins of the characters in question. 2 Specifically, I review pertinent data on the following widely recog - nized hominid genera and species: Australopithecus species (A. afarensis , A. africanus , and A. robustus [Paranthropus robustus]) , early Homo species (Australopithecus gahri , Homo habilis , and Homo rudolfensis) , and Middle Pleistocene Homo species (Homo erectus , Homo ergaster , and others), which I am calling erectines .

Shubin, University of Chicago, Chicago, IL, and approved September 10, 2014 (received for review April 25, 2014) Australopithecus fossils were regularly interpreted during the late 20th century in a framework that used living African apes, especially chimpanzees, as proxies for the immediate ancestors of the human clade. Such projection is now largely nullified by the discovery of Ardipithecus. In the context of accumulating evidence from genetics, developmental biology, anatomy, ecology, biogeography, and geology, Ardipithecus alters perspectives on how our earliest hominid ancestors—and our closest living relatives—evolved. human evolution | Australopithecus | hominid | Ethiopia “...the stock whence two or more species have chimpanzees, can serve as adequate repre- (5).

These fossils all date to between 4.195 and Accepted 7 May 2013 4.108 million years ago. Most were recovered from the lower fluvial sequence at the site, with one from Available online 30 August 2013 the lacustrine sequence deltaic sands that overlie the lower fluvial deposits but are still below the Kanapoi Tuff. The new specimens include a partial edentulous mandible, partial maxillary dentition, two Keywords: partial mandibular dentitions, and five isolated teeth. The new Kanapoi hominin fossils increase the Australopithecus anamensis sample known from the earliest Australopithecus, and provide new insights into morphology within this Kanapoi New fossils taxon. They support the distinctiveness of the early A. anamensis fossils relative to earlier hominins and Dentition to the later Australopithecus afarensis. The new fossils do not appreciably extend the range of observed variation in A. -

Homo heidelbergensis: The Tool to Our Success By Alexander Burkard Homo heidelbergensis, a physiological variant of the species Homo sapien, is an extinct spe- cies that existed in both Europe and parts of Asia from 700,000 years ago to roughly 300,000 years ago (carbon dating). This “subspecies” of Homo sapiens, as it is formally classified, is a direct ancestor of anatomically modern humans, and is understood to have many of the same physiological characteristics as those of anatomically modern humans while still expressing many of the same physiological attributes of Homo erectus, an earlier human ancestor. Since Homo heidelbergensis represents attributes of both species, it has therefore earned the classifica- tion as a subspecies of Homo sapiens and Homo erectus. Homo heidelbergensis, like anatomically modern humans, is the byproduct of millions of years of natural selection and genetic variation. It is understood through current scientific theory that roughly 200,000 years ago (carbon dat- ing), archaic Homo sapiens and Homo erectus left Africa in pursuit of the small and large animal game that were migrating north into Europe and Asia. -
