Ancient dapples

In previous work, Dr Ludwig, and his colleagues, recovered only the DNA of black and brown coat colours from the prehistoric horse bones.

But the dappled coats of the 25,000 year horses depicted at the Pech Merle cave complex in France convinced the team to take a second look.

By revisiting the fossil DNA of 31 horse specimens collected from across Europe, from Siberia to the Iberian Peninsula, the researchers found that six of the animals carried a mutation that causes modern horses to have white and black spots.

Of the remaining 25 specimens, 18 were brown coloured and six were black.

Dr Ludwig explained that all three of the horse colours - black, brown and spotted - depicted in the cave paintings have now been found to exist as real coat-colours in the ancient horse populations.
