Scientists spot genetic quirk that gives Solomon Islanders blonde hair. Up to 10 per cent of Solomon Islanders are naturally blonde. Picture: Sean Myles. Source: Supplied Dark-skinned, golden-haired Solomon Islanders get their striking locks from a gene mutation different from the one that makes some Europeans blonde, according to a study published Thursday. Up to 10 percent of the indigenous Melanesian people in the Solomon Islands have naturally blonde hair - the highest occurrence outside of Europe - but they also have the darkest skin pigmentation outside of Africa. Some islanders have theorized a diet rich in fish or an excess of sun exposure caused this phenomenon, while others believed the trait was passed down from liaisons with European explorers. But the new study, published in the journal Science, found the islanders' surprising hair color comes from a recessive genetic mutation that evolved independently of European DNA.
The researchers compared the genomes of Melanesian study participants, 43 with blonde hair and 42 with dark hair. Two Hundred Years of Surgery. Surgery is a profession defined by its authority to cure by means of bodily invasion. The brutality and risks of opening a living person's body have long been apparent, the benefits only slowly and haltingly worked out. Nonetheless, over the past two centuries, surgery has become radically more effective, and its violence substantially reduced — changes that have proved central to the development of mankind's abilities to heal the sick.
Surgery before the Advent of Anesthesia The first volume of the New England Journal of Medicine and Surgery, and the Collateral Branches of Science, published in 1812, gives a sense of the constraints faced by surgeons, and the mettle required of patients, in the era before anesthesia and antisepsis. The eye-lids were separated by the thumb and finger of the left hand, and then, a broad cornea knife was pushed through the cornea at the outer angle of the eye, till its point approached the opposite side of the cornea.
They were also often illusory. Twins married first wives named Linda, second wives named Betty, named sons James and dogs Toy- all before meeting for first time in 39 years after separation at birth.
