Researchers from King's College, London, have proven that tiger stripes are formed because of morphogens - a substance secreted by group of cells.
In 1950, Alan Turing, a famous code-breaker and mathematician suggested that repetitive patterns in biological systems were generated by a pair of morphogens that worked together as an "activator" and "inhibitor", of each cell.
Turing suggested the combined activity of these two morphogens were the reasons why some animals had stripes... and some spots.
The researchers sought to test theory on lab mice.
