Humanity's dramatic race across the Old World after it left its African cradle has been told countless times. But for a true sense of the rapidity of events, look no further than the Y chromosome. The most comprehensive analysis of the Y yet shows that within 150 years, an evolutionary blink of an eye, the first migrants to make it into Eurasia split into three distinct groups that can still be identified today. Men inherit their Y chromosome from their fathers.
Like all other chromosomes, the Y mutates over time so the more distant the relationship between two men, the more genetically distinct their Y chromosomes. In 2000, biologists used this fact to construct a family tree of all men, which shows how human populations around the world are related. But this tree was built using the information from a small samples of DNA on the Y chromosome, which revealed only around 100 sites of genetic variation that could help establish familial relations. 69 dudes A mountain high enough.

Jack Parsons was a founding member of Nasa's Jet Propulsion Lab, with some crediting him as being one of the "fathers of rocketry" and others joking that JPL was actually Jack Parsons' Laboratory, but you won't find much about him on Nasa's websites. Parsons' legacy as an engineer and chemist has been somewhat overshadowed by his interest in the occult and, and has led to what some critics describe as a rewriting of the history books.
"He's lived in the footnotes since his death. He's a forgotten figure," says biographer George Pendle, author of Strange Angel: The Otherworldly Life of Rocket Scientist John Whiteside Parson (Jack's full name). Pendle did an "archeological dig" into Parsons' life after finding a mention of him in a science book. "The more I dug, the more bizarre and extreme the story seemed. " Continue reading. BBC.
