From Ireland to Turkey, Europeans are all related, sharing a link with ancestors who were alive just 1,000 years ago, according to a new genetic study.
-
Peter Ralph and Graham Coop of the University of California used genomic data for 2,257 Europeans to conduct the first such study of an entire continent.
-
A separate study, based on DNA recovered from ancient skeletons, revealed last month that the genetic makeup of modern Europe was established by a wave of newcomers to the continent 6,500 years ago, more recently than previously thought.

other research suggests everyone alive in the world today shares a common ancestor from sometime in the past 3,500 years.
-
As recently as the 1950s, British schoolchildren were still studying pre-World War II textbooks that divided Europeans into Germanic, Alpine and Latin “types” according to the shape of their noses.
-
scientists had been arguing for 50 years that all humans were too closely related to be divided into races. “The few externally visible differences like skin color or nose shape are not enough to justify divisions,” he said.
-
Modern Italians and Spaniards have relatively few common ancestors compared with other European populations, which may be explained by their geography and history.

“There have been many studies that we’ve been involved in showing that groups which are fighting each other furiously all the time are actually extremely closely genetically related,” Mark A. Jobling, a geneticist at England’s Leicester University, told Associated Press. “So for example Jewish and non-Jewish populations in the Middle East are extremely similar genetically, but to tell them they are genetic close relatives isn’t going to change their ways.”
