Hobbits on Flores, Indonesia. Video. Australopithecus afarensis. Hominidae: Information. Until recently, most classifications included only humans in this family; other apes were put in the family Pongidae (from which the gibbons were sometimes separated as the Hylobatidae).
The evidence linking humans to gorillas and chimps has grown dramatically in the past two decades, especially with increased use of molecular techniques. It now appears that chimps, gorillas, and humans form a clade of closely related species; orangutans are slightly less close phylogenetically, and gibbons are a more distant branch. Here we follow a classification reflecting those relationships. Chimps, gorillas, humans, and orangutans make up the family Hominidae; gibbons are separated as the closely related Hylobatidae.

Human Evolution. Did Neanderthals speak with a high-pitched voice? Neanderthals had different bodies than we do.
In general, they were stockier and shorter, for instance. And there were other physical differences, as well. It's hard to say what these differences meant in practice but it's fun to speculate. You could build up a pretty good about how those short, study bodies might have helped Neanderthals be better adapted to cold. Or, you could look at the shape of a male Neanderthal's voice box, and think about how that shape might affect the sounds that came out. Keeping up with the Hominin. “Hominin – the group consisting of modern humans, extinct human species and all our immediate ancestors (including members of the genera Homo, Australopithecus, Paranthropus and Ardipithecus).”
Australian Museum. A lot had happened this year with hominin research and some would redefine conventional understandings of this group. Below is a list of new studies that came out this year that I find quite interesting on hominin. Did Humans Really Migrate From Africa? New Proof Could Undermine Out of Africa Theory. Newly discovered stone artifacts that suggest humanity left Africa through the Arabian Peninsula could re-write early human history.
More than 100 stone tools discovered in Oman showed that early humans were already living in southern Arabia much earlier than scientists had thought. Modern humans had first lived in Africa over 200,000 years ago but scientists believe that they didn't migrate worldwide until 40,000 to 70,000 years ago. The new study by an international team of researchers, show that the stone artifacts are at least 100,000 years old, which could blow that long believed theory out of the water. "After a decade of searching in southern Arabia for some clue that might help us understand early human expansion, at long last we've found the smoking gun of their exit from Africa," said lead researcher Jeffrey Rose, a paleolithic archaeologist at the University of Birmingham in England. "What makes this so exciting is that the answer is a scenario almost never considered. " Human Evolution. Evolution of human intelligence.
The evolution of human intelligence refers to a set of theories that attempt to explain how human intelligence has evolved.
These theories are closely tied to the evolution of the human brain and to the emergence of human language. Many traits of human intelligence, such as empathy, theory of mind, mourning, ritual, and the use of symbols and tools, are already apparent in great apes although in less sophisticated forms than found in humans. History Ancestry5_large.jpg (JPEG Image, 3000×1536 pixels) - Scaled (42%) Homo cepranensis – Three hundred times as ancient as Rome. Personality Types. While listing personality disorders is a fairly simple and straight-forward matter, listing personality types is infinitely more complex.
When talking of personality types we enter the field of theories... and there are several good ones! One of the most interesting theories is Keirsey's Temperament Sorter, inspired by Hippocrates' and Plato's ancient studies of temperament. The 16 types which result from the 4 temperaments correlate with the Myers-Briggs Type Indicator (MBTI)*, which is based on the typological theories by Carl Gustav Jung.

Evolutionary theory answers one of the most profound and fundamental questions human beings have ever asked themselves, a question that has plagued reflective minds for as long as reflective minds have existed in the universe: The question was answered in 1859 by the English naturalist Charles Darwin, and the answer can be stated in just six words: "What? " Te map. | The Smithsonian Institution's Human Origins Program. Te map. Human Evolution & Archaeology. Neanderthal genome yields insights into human evolution and evidence of interbreeding. After extracting ancient DNA from the 40,000-year-old bones of Neanderthals, scientists have obtained a draft sequence of the Neanderthal genome, yielding important new insights into the evolution of modern humans.
Among the findings, published in the May 7 issue of Science, is evidence that shortly after early modern humans migrated out of Africa, some of them interbred with Neanderthals, leaving bits of Neanderthal DNA sequences scattered through the genomes of present-day non-Africans. "We can now say that, in all probability, there was gene flow from Neanderthals to modern humans," said the paper's first author, Richard E. (Ed) Green of the University of California, Santa Cruz. Green, now an assistant professor of biomolecular engineering in the Baskin School of Engineering at UC Santa Cruz, began working on the Neanderthal genome as a postdoctoral researcher at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.
Ancestral Lines. Evolutionary biologists use a cladogram, the treelike diagram of evolutionary branches or clades, to organize species into lines of evolutionary descent across time.
Biologists use three types of evidence to deduce evolutionary connections: genetics, morphology, and geologic dating. (Behavior, normally a key part of evolutionary studies, can only be inferred in extinct species — for example, by examining the ecology in which the species flourished and the species adaptations for eating and locomotion.) Analyses of primate fossils and the genetic relatedness of living primates converge to the conclusion that humans and chimpanzees branched from a common ancestor about 7 million years ago. DNA recovered from several uncontaminated Neanderthalensis fossils indicated that modern humans and extinct neanderthals diverged about 400,000 years ago; but more recent studies show that they must have interbred within Europe or the Middle East since then.
Human evolution theory founded on female sexual selection and neoteny addressing autism, female infanticide, biological and cultural evolution. Timeline of human evolution. Haeckel's Paleontological Tree of Vertebrates (c. 1879).The evolutionary history of species has been described as a "tree", with many branches arising from a single trunk.
While Haeckel's tree is somewhat outdated, it illustrates clearly the principles that more complex modern reconstructions can obscure. The timeline of human evolution outlines the major events in the development of human species, and the evolution of humans' ancestors. It includes a brief explanation of some animals, species or genera, which are possible ancestors of Homo. Homo sapiens taxonomy Why human evolution accelerated. This is a story about my work on recent human evolution, describing some of the main results and how the work came about. The story refers to my paper (with Gregory Cochran, Eric Wang, Henry Harpending, and Robert Moyzis), "Recent acceleration of human adaptive evolution," which came out in December, 2007. Like most good stories in biology, this one begins with Darwin.
Darwin was always very interested in animal breeding, which he considered the best analogy for the process of natural selection. Of course, if you're breeding livestock and want to select for some characteristics, it is important to select from as large a herd as possible, because large populations have more variation in them. Darwin recognized this as an important condition for natural selection, which relies on sufficient variation in natural populations. Human Evolution-Science Tracer Bullet-Library of Congress.

An update of TB 73-13, this guide is intended for those who wish to review published materials on human evolution in the Library of Congress. Not an exhaustive treatment of the subject, this Tracer Bullet, as the name of the series implies, is designed to put the reader "on target.
" Human Evolution Happened Fastest Among Tibetans: Study. (Newser) – The Tibetan people have evolved to suit their high-altitude home with astonishing speed, say researchers. Biologists who compared the genomes of Tibetans living in villages up to 3 miles above sea level with Han Chinese found that 30 genes had undergone adaptive mutations in the 3,000 years since lowland Chinese first settled what is now Tibet, the New York Times reports. One gene found in almost 90% of Tibetans affects the production of red blood cells, allowing them to thrive in high-altitude, low-oxygen environments without the mountain sickness and lowered fertility that affects lowlanders.
The changes are the fastest-known example of human evolution, the researchers say, although some archeologists argue that the Tibetan-Chinese split happened much earlier than 3,000 years ago. Fossil Hominids: the evidence for human evolution. The Future of Human Evolution. Human Evolution: The fossil evidence in 3D.

The skull of the juvenile Australopithecus afarensis, dubbed 'Lucy's baby' Credit: Zeresenay Alemseged/Authority for Research and Conservation of Cultrual Heritages SYDNEY: The discovery of an infant human ancestor, dubbed ‘Lucy’s baby’, will shake up our understanding of human evolution, according to its finders in Dikika, Ethiopia. Two articles published today in the British journal Nature identified the fossil remains – the oldest and most complete infant skeleton found to date – as those of a three-year-old girl who lived 3.3 million years ago.
She belongs to the species Australopithecus afarensis, of which the iconic adult skeleton, nicknamed ‘Lucy’, is also a member. “The Dikika girl stands as one of the major discoveries in the history of palaeoanthropology,” research team leader Zeresenay Alemseged said, citing the remarkably well-preserved condition of the bones, the geological age and completeness of the specimen.
