rabbit evolution

does anyone know how a rabbits foot has evolved? i have some information about it but i need more.

thank you:biggrin:

"The rabbits feet are not just lucky, they let the bunny move through soft sand, snow or mud. The large feet of the rabbit act like "snowshoes" and provide needed float in soft terrain. This is especially helpful when they are running from predator species such as fox or lynx." - from ehow...

"The wild rabbit spends it's time moving about on grass and earth. These surfaces are compliant: they allow the toe nails to sink into the ground, encouraging the whole bottom of the foot to contact the ground and hence reducing the pressure on the foot (pressure = force divided by area)." - from rabbitwelfare

Hope it helps a bit... What info did you find?
