New Clues About Human Ancestry
2013-08-02 05:16:23

redOrbit Staff & Wire Reports - Your Universe Online For the first time, scientists have been able to trace human ancestry through the male line by sequencing the DNA of multiple entire Y chromosomes - and this so-called "Adam" lived during roughly the same time period as the female most recent common ancestor (MRCA), mitochondrial "Eve," they have discovered. The MRCAs, mitochondrial Eve and Y-chromosomal Adam, are two individuals who passed down a portion of their genomes to the...

Blondeness In Solomon Islanders Due To Genetic Variations
2012-05-04 08:38:37

Excess sun exposure, a diet rich in fish, and gene inheritance from ancient explorers and traders, are all possible theories why some dark-skinned indigenous Solomon Islanders are naturally blonde, according to new research published today in the journal Science. The study, led by Stanford University researchers, found that 5 to 10 percent of the indigenous Solomon population have a gene that is responsible for blondeness. The trait, however, is distinctly different from the gene that...

NSF-supported researchers map the genetic origins of "village" dogs on five continents By Marlene Cimons, National Science Foundation Most animal lovers can't resist bringing home the occasional stray dog. Imagine, then, having to fight this impulse every day, and on the other side of the world, all while trying to maintain some measure of scientific detachment. Ryan Boyko and his fellow researchers, who spent two years collecting blood samples from more than 1,200 stray dogs in dozens of...

Sure, dogs are special. You might not be aware, however, that studying their genomes can lead to advances in human health. So next time you gaze soulfully into a dog's eyes or scratch behind its ears, take note of the length of his nose or the size of his body. Although such attributes can vary wildly among different breeds, a team of investigators co-led by researchers at Stanford University School of Medicine, Cornell University and the National Human Genome Research Institute has found...

A tool for clinicians as well as geneaologists Understanding the genetic ancestry of mixed populations, such as those found in North America, can not only help to detect their origins but also to understand the genetic basis of complex diseases, a scientist will tell the annual conference of the European Society of Human Genetics today (Saturday June 11). It is the first time that the genomes of individuals of admixed ancestry have been sequenced in such detail, says Dr. Francisco De La Vega...

Human migration from Africa to Europe more than 30,000 years ago appears to have left a mark on the genes of Europeans today.A Cornell-led study, reported in the Feb. 21 issue of the journal Nature, compared more than 10,000 sequenced genes from 15 African-Americans and 20 European-Americans. The results suggest that European populations have proportionately more harmful variations, though it is unclear what effects these variations actually may have on the overall health of...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
