Did Neanderthals speak with a high-pitched voice? Neanderthals had different bodies than we do.

Did Neanderthals speak with a high-pitched voice?

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).”

Below is a list of new studies that came out this year that I find quite interesting on hominin. Read up so you can show off in class with your knowledge of current hominin research. You know, just so you can make sure that your adjunct is really paying attention of what he/she is doing instead of begrudgingly teaching a class because he/she has to.

Newly discovered stone artifacts that suggest humanity left Africa through the Arabian Peninsula could re-write early human history.

Did Humans Really Migrate From Africa? New Proof Could Undermine Out of Africa Theory

More than 100 stone tools discovered in Oman showed that early humans were already living in southern Arabia much earlier than scientists had thought. 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.

Evolution of human intelligence

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[edit] Hominidae[edit] Chimpanzee mother and baby The great apes show considerable abilities for cognition and empathy.

The Meaning of Life Revealed!

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.

Neanderthal genome yields insights into human evolution and evidence of interbreeding

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. Source. 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.

Ancestral Lines

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. 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.

Why human evolution accelerated

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.

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. Intelligent people have 'unnatural' preferences and values that are novel in human evolution. More intelligent people are significantly more likely to exhibit social values and religious and political preferences that are novel to the human species in evolutionary history.

Specifically, liberalism and atheism, and for men (but not women), preference for sexual exclusivity correlate with higher intelligence, a new study finds. The study, published in the March 2010 issue of the peer-reviewed scientific journal Social Psychology Quarterly, advances a new theory to explain why people form particular preferences and values. The theory suggests that more intelligent people are more likely than less intelligent people to adopt evolutionarily novel preferences and values, but intelligence does not correlate with preferences and values that are old enough to have been shaped by evolution over millions of years. " The Future of Homo Sapiens, The Future of Human Evolution. Will the human species, Homo Sapiens, continue to evolve in the next millions of years? If so, how? What can we learn from what we know about Homo Sapiens development until now?

(Humanity's Evolutionary Prehistoric Diet and Ape Diets--continued, Can you give us a timeline of dietary developments in the human line of evolution to show readers the overall picture from a bird's-eye view, so we can set a context for further discussion here? Sure. We need to start at the beginning of the primate line long before apes and humans ever evolved, though, to make sure we cover all the bases, including the objections often made by vegetarians (and fruitarians for that matter) that those looking into prehistory simply haven't looked far enough back to find our "original" diet.

Keep in mind some of these dates are approximate and subject to refinement as further scientific progress 65,000,000 to 50,000,000 B.C.: The first primates, resembling today's mouse lemurs, bush-babies, and tarsiers, weighing in at 2 lbs. or less, and eating a largely insectivorous diet.[8] Ken Miller on Human Evolution.

If Ardi’s skeleton was an unexpected mosaic, her habitat was even more curious. The Middle Awash scientists analyzed more than 150,000 vertebrate fossils from the site, from rats to foxes to saber-toothed cats, along with hundreds of geologic samples, to arrive at a detailed understanding of Ardi’s habitat. “It was like a whole series of snapshots across an ancient landscape,” White says. For decades anthropologists have argued the “savanna hypothesis”: that bipedalism evolved on the savannas of Africa as spreading grasslands forced our ancestors to walk increasing distances across open territory. As White and his team analyzed their evidence, they realized that Ardi must have lived in the woods.

In that case, bipedalism must have emerged for different reasons. But Ardi’s most important legacy could be the light she sheds on our last common ancestor, that mysterious creature that ultimately gave rise to both today’s humans and our closest living relatives, the chimpanzees. Ongoing human evolution could explain recent rise in certain disorders. The Chinese Room Argument. First published Fri Mar 19, 2004; substantive revision Wed Apr 9, 2014 The argument and thought-experiment now generally known as the Chinese Room Argument was first published in a paper in 1980 by American philosopher John Searle (1932- ). It has become one of the best-known arguments in recent philosophy.

Searle imagines himself alone in a room following a computer program for responding to Chinese characters slipped under the door. Searle understands nothing of Chinese, and yet, by following the program for manipulating symbols and numerals just as a computer does, he produces appropriate strings of Chinese characters that fool those outside into thinking there is a Chinese speaker in the room.

The narrow conclusion of the argument is that programming a digital computer may make it appear to understand language but does not produce real understanding. 1.
