	Human Evolution
		To the human, however, in his need to establish his place and purpose in the universe, the most important material is biological and the most important process is evolution, far it is only here that the human can learn to understand himself, an understanding that is vital to his survival.
		Evolution had honed the species to fit the environment and was now in balance.
		Evolution, through the liberal application of death and hardship, had built a strong body and a sound mind by the time of the appearance of Homo sapiens sapiens.

	Human Evolution - MSN Encarta
		Humans and the so-called great apes (large apes) of Africa—chimpanzees (including bonobos, or so-called pygmy chimpanzees) and gorillas—share a common ancestor that lived sometime between 8 million and 6 million years ago.
		Paleoanthropology is a subfield of anthropology, the study of human culture, society, and biology.
		Humans belong to the scientific order named Primates, a group of over 230 species of mammals that also includes lemurs, lorises, tarsiers, monkeys, and apes.

	Human Evolution
		Humans are members of the order Primates which consists of about 180 species (there are 17 different orders of mammals which diverged 80-65 million years ago).
		Humans are a member of the family Hominidae which is believed to have diverged about 5 million years before the present (mybp) from the other members of the Old world monkeys.
		The first human (Australopithecus afarensis) seems to have an angle between the femur and tibia (Upper and lower leg) that is intermediate to that of humans and gorillas.

	Human evolution at the crossroads: Integrating genetics and paleontology
		Using her own research on the teeth of baboons as a case in point, Leslea J. Hlusko said that some of the traits considered important to human evolution, such as the thickness of molar enamel, may be too simplistically interpreted by some paleontologists.
		Hlusko organized a Monday symposium on human evolution at the annual meeting of the American Association for the Advancement of Science.
		She brought together experts who study phylogenetics, ancient DNA, developmental genetics, quantitative genetics and primate evolution so that they could share the same stage to discuss their current work, and where they may be able to go on together in an effort to understand the evolution of our ancestors.

	Teach Evolution and Make it Relevant
		Humans and the great apes—chimpanzees in particular—diverged from a common ancestor as recently as about 7 – 8 million years ago (Mya); the transition from this common ancestor to modern humans has been well documented.
		Humans, for example, have evolved the ability to walk upright (bipedalism), a much larger and more complex brain, a much greater intellectual capacity, language (spoken and written), and the ability to precisely manipulate very small objects with their hands, among others traits.
		A classic lesson on human evolution is the skull comparison, in which students compare the skull characteristics of contemporary humans and apes (such as chimps or gorillas), with fossil hominids.

	Man's early hunting role in doubt - human-evolution - 06 January 2003 - New Scientist (Site not responding. Last check: 2007-10-24)
		Hunting skills may not after all have triggered the tremendous burst of human evolution at the beginning of the ice ages nearly two million years ago.
		Based on that observation, the team estimated that early humans might have picked up a carcass every few days in the wettest areas, but in drier areas might have got as little as one a month: nowhere near enough to live on.
		Evolution would thus favour a long lifespan, which is closely linked to large body size and delayed maturity.

		Like humans, chimpanzee groups generally practice female dispersal and male philopatry, as Anne Pusey points out in her introductory chapter, with the result, as de Waal notes, that males have less to lose from incest than do females.
		Philosopher Carruthers and biological anthropologist Chamberlain bring together in Evolution and the Human Mind anthropologists, linguists and even behavioral geneticists in their effort to understand the human mind through evolution.
		Dunbar concludes that hominid group sizes began to exceed those that could be held together by grooming alone somewhere toward the end of the Homo erectus phase, implying that language had taken on part of the role of facilitating social cohesion by that time.

	Human Evolution — Infoplease.com
		The story of human evolution began in Africa about six million years ago and it describes the very long process that our ancestors went through to ultimately become modern humans.
		Human brains are larger and more complex; people have elaborate forms of communication and culture; and people habitually walk upright, can manipulate very small objects, and can speak.
		The very early years of the transition from ape to human, from 6 million to 4 million years ago, is poorly documented in the fossil record, but those fossils that have been discovered document the most primitive combinations of ape and human features.

	Reverse human evolution plausible, testable, U.S. biologist says
		Reverse evolution occurs when an organism returns to the genetic state of its ancestors, said Crandall, who wrote a paper on the topic in the Oct. 2003 issue of the research journal Trends in Ecology and Evolution.
		Evolution is the process in which occasional helpful mutations spread throughout a population, as the organisms that have them reproduce more.
		Scientific doubts on reverse evolution, Crandall wrote, have nothing to do with a popular misconception that evolution “has no direction.” It does in part, he argued—species tend to become better suited to their environment—and that may be irrelevant anyway, since reversion to ancestral genes can occur whether or not one thinks of evolution as directed.

		The rate of evolution of the rest of the genome was surprisingly even between different sites, different genes and also between the different gene complexes.

	Human evolution
		The comparisons within and between species suggest that about 9 percent of genes that show some variability within humans or differences between humans and chimpanzees have evolved too rapidly to be explained simply by chance.
		Likewise, the researchers found that approximately 13 percent of the genes that may vary show evidence of slightly deleterious or harmful mutations in human populations; these include genes involved in determining the basic structure of cells and muscles as well as genes that control traffic in and out of the cell.
		By comparing the DNA sequences of the 39 human subjects across the 20,000 genes, the Celera researchers identified DNA sites in the genome where individuals in the sample differed from one another.
