They say red hair may soon become extinct. Redheads have a gene that allows them to create their own vitamin D, whilst non red-haired people are able to create theirs from exposure to sunlight. The effects of global warming heating up the planet means that even the Scots are now getting plenty of ray, thus the need for the redhead gene is in decline. Darwin may argue that this is all fair play, but it comes at a price. Here's a gallery celebrating our favourite beautiful redheads, fiery gingers and ravishing rangas from film, TV and music. Screw you, evolutionary biology.
