The mule’s commitment to survival is interesting in a Darwinian context, because mules–the hybrid result of mating a male donkey with a female horse–have an uneven number of chromosomes and are therefore sterile.

Since a horse and a donkey rarely mate on their own, mules are essentially man-made. It has been a successful invention–in fact, mules are probably the most successful and enduring animal hybrid, with beefalo coming in a distant second.
