Hair bleach a possible key to life

Next time you dye your hair blonde, you may just be holding a key to life on Earth in your bleach bottle.

University mathematicians believe hydrogen peroxide, the common ingredient in hair bleach, may have provided the energy source for the development of life on earth.

"Hydrogen peroxide has just enough oxidising power to cause mutations every now and then, which would drive evolution," Australian National University associate professor Rowena Ball said in a statement.
