Human Y Chromosome Found To Be Much Older Than Previously Believed
2013-03-06 05:56:19

redOrbit Staff & Wire Reports - Your Universe Online Researchers have discovered a Y chromosome — the hereditary factor determining male sex — that dates back to 100,000 years before the oldest known anatomically modern human fossils. The chromosome was originally obtained from an African-American man living in South Carolina. It was originally submitted to the National Geographic Genographic Project — a research project that utilizes genetic and computational...

Gene Mutation Responsible For Severe Form Of Epilepsy Identified
2012-02-24 06:02:48

Researchers at the University of Arizona have identified a previously unknown mutation in a sodium channel protein in the central nervous system as the likely cause of a severe form of epilepsy. Such deciphering of the genetic information from a single individual in a matter of weeks to find a certain disease-causing genetic mutation would have been unthinkable just a decade ago. But today, a team of researchers led by Michael Hammer applied Next Generation Genome Sequencing to decipher...

Evolution's Past Is Modern Human's Present

  Mandenka, Biaka and San tested for DNA evidence of ancient interbreeding inside Africa The past is present when it comes to human evolution. That seems to be the takeaway from new research that concludes "archaic" humans, somewhere in Africa during the last 20-60 thousand years, interbred with anatomically modern humans and transferred small amounts of genetic material to their offspring who are alive today. University of Arizona geneticist Michael Hammer and a team of...

Ancient Humans Interbred With Other Hominin Species
2011-09-06 05:10:50

  A new study finds that our ancestors bred with more archaic hominin forms around 35,000 years ago, before they migrated out of Africa. In fact, up to 2% of the genomes of some modern African populations may originally have come from a closely related species, the researchers said. It is widely accepted that the species Homo sapiens originated in Africa, and eventually spread throughout the world.  However, paleontologists have long wondered whether modern humans came from...
