Majority of European Men descended from just Three Ancestors

Two-thirds of modern-day European males trace their genetic roots to just three Bronze Age forbears, who almost literally launched the “population explosion” many centuries ago, a new DNA study suggests.
Before coming to this conclusion, a research team from the University of Leicester analyzed the DNA sequences of 334 modern European men from 17 different European and Middle Eastern populations, focusing on the large portions of the Y-chromosome passed exclusively from fathers to sons.
Those branches of the European genetic tree are fairly young, which suggests most modern populations settled in Europe only after the spread of farming during the Neolithic era, rather than during the period of hunter-gatherers moving across the continent in the Paleolithic era, as previously thought.
Although it is still unclear who exactly the ‘fathers’ in these paternal lineages were, or even if they were born in Europe, the scientists believe they were influential and powerful individuals, likely tribal chieftains.
“We think that a social structure in which resources and power are more easily accessible to only some men may allow for a few paternal lineages to become very frequent in a short amount of time,” Dr. Chiara Batini, a co-author of the research and a geneticist at the University of Leicester, said.
One mutation they found originated around 4,750 to 7,340 years ago and is prevalent in Norwegian and Orcadian populations. The second occurred between 3,700 and 6,500 years ago and has spread throughout Spain, Italy, France, England and Ireland. The third dated from about 3,470 to 5,070 years ago is prominent in the Sami in Lapland, Norwegians, Danes and Friesian populations in the Netherlands, as well as being found in France, Hungary, Serbia and Bavaria, the study reports.
According to the researchers, these three paternal lines account for about 63 percent of modern European men. That means that from 371.25 million males currently living in Europe around 233 million are descendants of just three men, as reported by the Daily Mail.
"Dominant males linked with these cultures could be responsible for the Y chromosome patterns we see today," he added.
According to the researchers, people in positions of power would tend to travel more widely and father far more children than their subjects, so their lineages became dominant.

White Indian Wants to Wear Feather in Graduation Cap to Show Pride in Her Native Culture

A Caney Valley High School student has once again been told she can't wear an eagle feather in her graduation cap. 
Hayden Griffith wants to wear the feather as a way to show pride in her Native culture, but the school district said it violates school policy to decorate mortar boards. 
On Tuesday after a day in federal court, a magistrate sided with the school district. It means Griffith will not get to wear a feather that she says has special religious significance. 
Hayden testified the eagle feather was a symbol of her religion and accomplishment. 
The school has offered alternatives, saying she can carry it or wear it in her hair, but Griffith considers that disrespectful to the Native American symbol of faith.
