The Cambridge Animal Alphabet series celebrates Cambridge's connections with animals through literature, art, science and society. Here, H is for Horse – 170-year-old model teeth, the Parthenon friezes, and the surprising origins of racehorses' speed.
The identity of the winner of the 1880 Epsom Derby – the classic race to be run today - was famously disputed. Now analysis of DNA from the bones of historic horses has solved the mystery conclusively - and has confirmed the authenticity of the skeleton of one of the most famous stallions of all time.
Research by a team of scientists suggests that a variant of the so-called speed gene found in top racehorses can be traced back to a single British mare living around 300 years ago. That mare may have had a similar genetic make-up to today's sturdy native ponies.
