Mice Thrive Missing Ancient DNA Sequences
September 6, 2007 — Ultraconserved elements are DNA sequences, hundreds of base pairs long, that are 100-percent identical in mice, rats and humans. Their perfect conservation for over 80 million years was thought due ... > full story -
Ethiopian Plateau Formation Coincided With Climate Change That May Have Spurred Human Evolution
August 31, 2007 — More than three million years ago, early hominins evolved the ability to walk upright and in doing so started us along the evolutionary path that eventually gave rise to Homo sapiens. It was Darwin ... > full story -
Handsome By Chance: Why Humans Look Different From Neanderthals
August 16, 2007 — Chance, not natural selection, best explains why the modern human skull looks so different from that of its Neanderthal relative. The scientists concluded that Neanderthals did not develop their ... > full story -
Facial Attraction: Choice Of Sexual Partner Shaped The Human Face
August 15, 2007 — Men with large jaws, flaring cheeks and large eyebrows are sexy, at least in the eyes of our ancestors, researchers at the Natural History Museum have discovered. Facial attractiveness played a major ... > full story -
New Kenyan Fossils Challenge Established Views On Early Evolution Of Our Genus Homo
August 13, 2007 — Two new fossils cast fresh light on a little understood and important period of human prehistory at the dawn of our own genus, Homo. One of the two fossils, an upper jaw bone of Homo habilis (KNM-ER ... > full story -
Early Modern Human Skull Includes Surprising Neanderthal Feature
August 10, 2007 — In 1942, a human braincase was found in Romania during phosphate mining. The skull's geological age has remained uncertain. Now, new radiocarbon analysis directly dates the skull to approximately ... > full story -
Genomics Study Provides Insight Into The Evolution Of Unique Human Traits
July 31, 2007 — Researchers report the results of a large-scale, genome-wide study to investigate gene copy number differences among ten primate species, including humans. In the report, the scientists speculate how ... > full story -
Back To The Future: Mastodon Extends The Time Limit On DNA Sequencing
July 30, 2007 — The first complete mitochondrial DNA genome for the mastodon extends the age range for genomic analyses by almost a complete glacial cycle, and resolves the relationships among African and Asian ... > full story -
Why Humans Walk On Two Legs
July 20, 2007 — A team of anthropologists that studied chimpanzees trained to use treadmills has gathered new evidence suggesting that our earliest apelike ancestors started walking on two legs because it required ... > full story -
New Research Proves Single Origin Of Humans In Africa
July 19, 2007 — New research has proved the single origin of humans theory by combining studies of global genetic variations in humans with skull measurements across the world. The research represents a final blow ... > full story -
Study Identifies Energy Efficiency As Reason For Evolution Of Upright Walking
July 17, 2007 — A new study provides support for the hypothesis that walking on two legs, or bipedalism, evolved because it used less energy than quadrupedal knucklewalking. Humans walking on two legs only used ... > full story -
Evidence Of Very Recent Human Adaptation: Up To 10 Percent Of Human Genome May Have Changed
July 12, 2007 — A Cornell University study of genome sequences in African-Americans, European-Americans and Chinese suggests that natural selection has caused as much as 10 percent of the human genome to change in ... > full story
