Annual Review of Nutrition. Retrieved August 2, Hominids can be broken down into two subfamilies, Ponginae, which includes orangutans Pongo and Hominae, which includes gorillas Gorilla , chimps Pan , and humans and their extinct close relatives such as Neanderthals Homo. Around six million years ago, the evolutionary line which gave rise to humans separated from the chimpanzees. Model of the phylogeny of Hominidae , with adjacent branches of Hominoidea , over the past 20 million years. Susman posited that modern anatomy of the human opposable thumb is an evolutionary response to the requirements associated with making and handling tools and that both species were indeed toolmakers. About 1. Homo erectus. Biennial Review of Anthropology. Perhaps in a sun-baked salt plain in Botswana," 31 Oct. Recent sequencing of Neanderthal [92] and Denisovan [93] genomes shows that some admixture with these populations has occurred. The immediate survival advantage of encephalization is difficult to discern, as the major brain changes from Homo erectus to Homo heidelbergensis were not accompanied by major changes in technology. Johnson Gad Saad. Brazilian Archives of Biology and Technology. Chiromyiformes Daubentoniidae. Although most living species are predominantly quadrupedal , they are all able to use their hands for gathering food or nesting materials, and, in some cases, for tool use. Dating back 11, years - with a coded message left by ancient man from the Mesolithic Age - the Shigir Idol is almost three times as old as the Egyptian pyramids. The study, by the University of York, reveals But, we still need a way to discuss humans and their ancestors as a separate group, so researchers have proposed a further breakdown of the Homininae subfamily, to include Hominini hominins or humans and their ancestors , Panini pan or chimpanzees and bonobos , and Gorillini gorillas. It walked on two legs biped and had its hands free to defend from predators. The theory of mind concept—including such faculties as empathy, attribution of mental state, and even empathetic deception—is a controversial criterion; it distinguishes the adult human alone among the hominids. Retrieved 2 July Several revisions in classifying the great apes have caused the use of the term "hominid" to vary over time. The Neanderthal populations seem to have been physically superior to AMH populations. On the basis of the early date of Badoshan Iranian Aurignacian, Oppenheimer suggests that this second dispersal may have occurred with a pluvial period about 50, years before the present, with modern human big-game hunting cultures spreading up the Zagros Mountains, carrying modern human genomes from Oman, throughout the Persian Gulf, northward into Armenia and Anatolia, with a variant travelling south into Israel and to Cyrenicia. Most paleoanthropologists agree that the early Homo species were indeed responsible for most of the Oldowan tools found. Evolution 3rd ed. The earliest fossils argued by some to belong to the human lineage are Sahelanthropus tchadensis 7 Ma and Orrorin tugenensis 6 Ma , followed by Ardipithecus 5. Homo sapiens is the only extant species of its genus, Homo. A drawback is that the birth canal of bipedal apes is smaller than in knuckle-walking apes, though there has been a widening of it in comparison to that of australopithecine and modern humans, permitting the passage of newborns due to the increase in cranial size but this is limited to the upper portion, since further increase can hinder normal bipedal movement. Retrieved 17 July Hominids Writer A cladogram indicating common names cf. The immediate survival advantage of encephalization is difficult to discern, as the major brain changes from Homo erectus to Homo heidelbergensis were not accompanied by major changes in technology. Thus, many biologists now assign Pongo as the sub family Ponginae to the family Hominidae. Vertebrate Paleobiology and Paleoanthropology. It also seems that the higher body mass of Neanderthals had a correspondingly larger brain mass required for body care and control. In , Randall Susman used the anatomy of opposable thumbs as the basis for his argument that both the Homo and Paranthropus species were toolmakers. The studies of ontogeny, phylogeny and especially evolutionary developmental biology of both vertebrates and invertebrates offer considerable insight into the evolution of all life, including how humans evolved. Researchers have suggested that early hominins were thus under evolutionary pressure to increase their capacity to create and use tools. Stone tools are first attested around 2. There is little fossil evidence for the divergence of the gorilla, chimpanzee and hominin lineages. Usage still varies, however, and some scientists and laypersons still use "hominid" in the original restrictive sense; the scholarly literature generally shows the traditional usage until around the turn of the 21st century. We're intent on clearing it up 'Nip it in the butt' or 'Nip it in the bud'? After , BP the more refined so-called Levallois technique was developed, a series of consecutive strikes, by which scrapers, slicers "racloirs" , needles, and flattened needles were made. Josh; Robertson, Marcia L. July 17, Retrieved 17 July Around six million years ago, the evolutionary line which gave rise to humans separated from the chimpanzees. In Ungar, Peter ed. There is still some debate among academics whether certain African hominid species of this time, such as Au. Additional research with offspring of wild chimpanzee populations in eight locations suggests that chimpanzees reproduce at age The current, 21st-century meaning of "hominid" includes all the great apes including humans.

Darwin's book did not address the question of human evolution, saying only that "Light will be thrown on the origin of man and his history. From brain Endocasts, Neanderthals also had significantly larger brains. Much of the evidence for the first group's expansion would have been destroyed by the rising sea levels at the end of each glacial maximum. Berkeley: University of California Press. Hominids Reviews The hypothesis of interbreeding, also known as hybridization, admixture or hybrid-origin theory, has been discussed ever since the discovery of Neanderthal remains in the 19th century.

Weidenreich concluded in that because of their anatomical similarity with modern humans it was necessary to gather all these specimens of Java and China in a single species of the genus Homo , the species Homo erectus. Fossils at 20 million years ago include fragments attributed to Victoriapithecus , the earliest Old World monkey. Geologic Timeline. HLA haplotypes from Denisovans and Neanderthal represent more than half the HLA alleles of modern Eurasians, [96] indicating strong positive selection for these introgressed alleles.

Evolution serves as a foundation to many biological concepts by tying together the different tenants of biology, like ecology, anatomy, genetics, zoology, and taxonomy. It is for this reason that evolution plays a prominent role in the state and national standards and deserves thorough coverage in a classroom. A prime example of evolution can be seen in our own ancestral history, and this unit provides students with an excellent opportunity to consider the multiple lines of evidence that support hominid evolution. By allowing students the chance to uncover the supporting evidence for evolution themselves, they discover the ways the theory of evolution is supported by multiple sources. It is our hope that the opportunity to handle our ancestors’ bone casts and examine real molecular data, in an inquiry based environment, will pique the interest of students, ultimately leading them to conclude that the evidence they have gathered thoroughly supports the theory of evolution.

This review details both what is firmly understood (first echelon issues) and what is contentious concerning humanSAMPLE evolution. Most of the coCHAPTERSntention actually concerns the details (second echelon issues) of human evolution rather than the fundamental issues. For example, both anatomical and molecular evidence on living (extant) hominoids (apes and humans) suggests the close relationship of African great apes and humans (hominins). That relationship is demonstrated by the existing hominoid fossil record, including that of early hominins.

  • Using Sub-Species Level Phylogenies
    1 Reconstructing the ancestral phenotypes of great apes and 2 humans (Homininae) using sub-species level phylogenies 3 Keaghan Yaxley1 and Robert Foley2 4 1Leverhulme Centre for Human Evolutionary Studies, University of Cambridge, UK 5 2Leverhulme Centre for Human Evolutionary Studies, University of Cambridge, UK 6 7 8 1 9 Abstract 10 By their close affinity, the African great apes are of interest to the study of human evolution. 11 While numerous researchers have described the ancestors we share with these species with 12 reference to extant great apes, few have done so with phylogenetic comparative methods. 13 One obstacle to the application of these techniques is the within-species phenotypic variation 14 found in this group. Here we leverage this variation, modelling common ancestors using 15 Ancestral State Reconstructions (ASRs) with reference to subspecies level trait data. A 16 subspecies level phylogeny of the African great apes and humans was estimated from full- 17 genome mtDNA sequences and used to implement ASRs for fifteen continuous traits known 18 to vary between great ape subspecies. While including within-species phenotypic variation 19 increased phylogenetic signal for our traits and improved the performance of our ASRs, 20 whether this was done through the inclusion of subspecies phylogeny or through the use of 21 existing methods made little difference. Our ASRs corroborate previous findings that the Last 22 Common Ancestor (LCA) of humans, chimpanzees and bonobos was a chimp-like animal, 23 but also suggest that the LCA of humans, chimpanzees, bonobos and gorillas was an animal 24 unlike any extant African great ape.

  • Origin of Language
    Origin of language The origin of language in the human species has been the topic of scholarly discussions for several centuries. There is no consensus on the origin or age of human language. The topic is difficult to study because of the lack of direct evidence. Consequently, scholars wishing to study the origins of language must draw inferences from other kinds of evidence such as the fossil record, archaeological evidence, contemporary language diversity, studies of language acquisition, and comparisons between human language and systems of communication existing among other animals (particularly other primates). Many argue that the origins of language probably relate closely to the origins of modern human behavior, but there is little agreement about the implications and directionality of this connection. This shortage of empirical evidence has led many scholars to regard the entire topic as unsuitable for serious study. In 1866, the Linguistic Society of Paris banned any existing or future debates on the subject, a prohibition which remained influential across much of the western world until late in the twentieth century.[1] Today, there are various hypotheses about how, why, when, and where language might have emerged.[2] Despite this, there is scarcely more agreement today than a hundred years ago, when Charles Darwin's theory of evolution by natural selection provoked a rash of armchair speculation on the topic.[3] Since the early 1990s, however, a number of linguists, archaeologists, psychologists, anthropologists, and others

  • Environmental Hypotheses of Hominin Evolution
    YEARBOOK OF PHYSICAL ANTHROPOLOGY 41:93–136 (1998) Environmental Hypotheses of Hominin Evolution RICHARD POTTS Human Origins Program, National Museum of Natural History, Smithsonian Institution, Washington, DC 20560-0112 KEY WORDS climate; habitat; adaptation; variability selection; fossil humans; stone tools ABSTRACT The study of human evolution has long sought to explain major adaptations and trends that led to the origin of Homo sapiens. Environmental scenarios have played a pivotal role in this endeavor. They represent statements or, more commonly, assumptions concerning the adap- tive context in which key hominin traits emerged. In many cases, however, these scenarios are based on very little if any data about the past settings in which early hominins lived. Several environmental hypotheses of human evolution are presented in this paper. Explicit test expectations are laid out, and a preliminary assessment of the hypotheses is made by examining the environmental records of Olduvai, Turkana, Olorgesailie, Zhoukoudian, Combe Grenal, and other hominin localities. Habitat-specific hypotheses have pre- vailed in almost all previous accounts of human adaptive history. The rise of African dry savanna is often cited as the critical event behind the develop- ment of terrestrial bipedality, stone toolmaking, and encephalized brains, among other traits. This savanna hypothesis has been countered recently by the woodland/forest hypothesis, which claims that Pliocene hominins had evolved in and were primarily attracted to closed habitats. The ideas that human evolution was fostered by cold habitats in higher latitudes or by seasonal variations in tropical and temperate zones also have their propo- nents. An alternative view, the variability selection hypothesis, states that large disparities in environmental conditions were responsible for important episodes of adaptive evolution.

Raya Condet Pejaten No. 4, Jakarta 12001, Indonesia ........................................................................................................................................................................................................................... Currently, it is widely accepted that only one hominin genus, Homo, was present in Pleistocene Asia, represented by two species, Homo erectus and Homo sapiens. Both species are characterized by greater brain size, increased body height and smaller teeth relative to Pliocene Australopithecus in Africa. Here we report the discovery, from the Late Pleistocene of Flores, Indonesia, of an adult hominin with stature and endocranial volume approximating 1 m and 380 cm3, respectively—equal to the smallest-known australopithecines. The combination of primitive and derived features assigns this hominin to a new species, Homo floresiensis. The most likely explanation for its existence on Flores is long-term isolation, with subsequent endemic dwarfing, of an ancestral H. erectus population. Importantly, H. floresiensis shows that the genus Homo is morphologically more varied and flexible in its adaptive responses than previously thought. The LB1 skeleton was recovered in September 2003 during archaeo- hill, on the southern edge of the Wae Racang river valley.

  • The Mysterious Phylogeny of Gigantopithecus
    Kimberly Nail Department ofAnthropology University ofTennessee - Knoxville The Mysterious Phylogeny of Gigantopithecus Perhaps the most questionable attribute given to Gigantopithecus is its taxonomic and phylogenetic placement in the superfamily Hominoidea. In 1935 von Koenigswald made the first discovery ofa lower molar at an apothecary in Hong Kong. In a mess of"dragon teeth" von Koenigswald saw a tooth that looked remarkably primate-like and purchased it; this tooth would later be one offour looked at by a skeptical friend, Franz Weidenreich. It was this tooth that von Koenigswald originally used to name the species Gigantopithecus blacki. Researchers have only four mandibles and thousands ofteeth which they use to reconstruct not only the existence ofthis primate, but its size and phylogeny as well. Many objections have been raised to the past phylogenetic relationship proposed by Weidenreich, Woo, and von Koenigswald that Gigantopithecus was a forerunner to the hominid line. Some suggest that researchers might be jumping the gun on the size attributed to Gigantopithecus (estimated between 10 and 12 feet tall); this size has perpetuated the idea that somehow Gigantopithecus is still roaming the Himalayas today as Bigfoot. Many researchers have shunned the Bigfoot theory and focused on the causes of the animals extinction. It is my intention to explain the theories ofthe past and why many researchers currently disagree with them. It will be necessary to explain how the researchers conducted their experiments and came to their conclusions as well. The Research The first anthropologist to encounter Gigantopithecus was von Koenigswald who happened upon them in a Hong Kong apothecary selling "dragon teeth." Due to their large size one may not even have thought that they belonged to any sort ofprimate, however von Koenigswald knew better because ofthe markings on the molar.
