Evolution by Keiwan ~ Use joints, bones and muscles to build creatures that are only limited by your imagination. Watch how the combination of a neural network and a genetic algorithm can enable your creatures to "learn" and improve at their given tasks all on their own.
Mitochondrial DNA and human evolution - PubMed ~ Several unique properties of human mitochondrial DNA (mtDNA), including its high copy number, maternal inheritance, lack of recombination, and high mutation rate, have made it the molecule of choice for studies of human population history and evolution. Here we review the current state of knowledge …
How a DNA revolution has decoded the origins of our ~ DNA taken from his thigh bone indicates he was a member of Homo sapiens who possessed a distinctive genetic lineage that has since disappeared entirely from the human gene pool.
NOVA Online / Cracking the Code of Life - PBS ~ NOVA Online/Cracking the Code of Life. Cracking the Code of Life," originally broadcast on April 17, 2001. This two-hour special, hosted by ABC "Nightline" correspondent Robert Krulwich .

human evolution / Stages & Timeline / Britannica ~ Human evolution, the process by which human beings developed on Earth from now-extinct primates. Viewed zoologically, we humans are Homo sapiens, a culture-bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago. We are now the only living members of what many zoologists refer to as the human tribe, Hominini, but there is .

DNA / Definition, Discovery, Function, Bases, Facts ~ DNA, organic chemical of complex molecular structure found in all prokaryotic and eukaryotic cells. It codes genetic information for the transmission of inherited traits. The structure of DNA was described in 1953, leading to further understanding of DNA replication and hereditary control of cellular activities.
DNA Science Disproves Human Evolution / The Institute for ~ The Evolution of Human-Chimp DNA Research. Although paleontological evidence has been lacking, in more recent times evidence supporting human evolution was thought to have been found in the DNA of living apes and humans. This article will evaluate the popular myth of human-chimpanzee DNA similarity along with recent research showing that a broad and unbridgeable chasm exists between the human .
Genetic 'Adam' and 'Eve' Uncovered / Live Science ~ The rest of the human genome contains tiny snippets of DNA from many other ancestors — they just don't show up in mitochondrial or Y-chromosome DNA, Hammer said. (For instance, if an ancient .
What is a gene?: MedlinePlus Genetics ~ In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. An international research effort called the Human Genome Project, which worked to determine the sequence of the human genome and identify the genes that it contains, estimated that humans have between 20,000 and 25,000 genes.
Human Genomic Variation - Genome.gov ~ The Human Genome Project has also led to a change in our understanding of human traits and how we teach them - one example is eye color. For many years, students were taught that one dominant gene controlled brown or blue eyes and that blue-eyed parents could not have brown-eyed children. Scientists knew that the blue-eyes trait was actually more complicated despite what was taught in schools .
Oldest Human DNA Reveals Mysterious Branch of Humanity ~ The DNA, which dates back some 400,000 years, may belong to an unknown human ancestor, say scientists. These new findings could shed light on a mysterious extinct branch of humanity known as .
Tibetans inherited high-altitude gene from ancient human ~ A “superathlete” gene that helps Sherpas and other Tibetans breathe easy at high altitudes was inherited from an ancient species of human. That’s the conclusion of a new study, which finds .
Oldest ancient-human DNA details dawn of Neanderthals ~ In decoding just 0.1% of the genome of the oldest DNA ever recovered from an ancient human, the molecular biologist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany .
What's Hot in Human Origins? - Human Evolution by The ~ The genome of 430,000-year-old fossils. Welcome to a new member of our family tree! Homo naledi discovered in an African cave The oldest fossil of our genus. And a new look at Homo habilis. Neanderthals: larger eyes and smaller brains? A new comparison with Homo sapiens. Complete skull from Dmanisi. Only one lineage of early Homo? Australopithecus sediba – new analyses and surprises. A .
The Tardigrade Genome Has Been Sequenced, And It's Even ~ Scientists have sequenced the entire genome of the tardigrade, AKA the water bear, for the first time.And their results suggest that this weird little creature has the most foreign genes of any animal studied so far – or to put it another way, roughly one-sixth of the tardigrade's genome was stolen from other species.
Neanderthal genome project - Wikipedia ~ The Neanderthal genome project is an effort of a group of scientists to sequence the Neanderthal genome, founded in July 2006.. It was initiated by 454 Life Sciences, a biotechnology company based in Branford, Connecticut in the United States and is coordinated by the Max Planck Institute for Evolutionary Anthropology in Germany. In May 2010 the project published their initial draft of the .
[current-page:page-title] / [site:name] ~ Ancient DNA and Neanderthals. While DNA can be used to understand aspects of biology and evolution, the fact that DNA is a fragile molecule and decays over time has made it difficult to use DNA to learn more about extinct species.After decades of work, scientists can now use ancient DNA to understand aspects of the biology of our closest extinct relatives, the Neanderthals (Homo .
9 Animals Who Have More In Common With Humans Than You ~ It wasn't until 2012 that we learned bonobos vary only slight from chimps. In fact, the two share 99.6 percent of their DNA. That means they're almost as close to humans on the genome sequence as chimpanzees are. Researchers believe the three of us separated on the evolutional path between 4 and 7 million years ago.
