Geneticists compared mitochondrial DNA from blue-eyed individuals in countries as diverse as Jordan, Denmark, and Turkey, concluding that people with blue eyes have a single common ancestor that lived by the Black sea around 8,000 years ago, spreading out with agriculture.
A US scientist has claimed to have found evidence of a ''sixth sense'' in humans that can detect the Earth's magnetic fields.
Joe Kirschvink, from the California Institute of Technology, says his experiment can also be ''repeated and verified'', something research on magnetoreception has never been able to do before.
The trial, which involved just 24 people and has not yet been peer reviewed, builds on a 2016 study that suggested other mammals, including dogs, foxes and primates have ''magnetic sensors''in their eyes.
Using a Faraday cage and a EEG monitor, Kirschvink observed reproducible changes in human alpha brain waves when adjustments were made to the magnetic field around them.
