Martin asked
"Why aren't rabbits green?"

Part Answer: they can become red!

The rabbit, introduced to Australia in the last century,
expanded its range to cover almost the entire temperate
region. Evolution has taken place quite rapidly - the
rabbit is now a larger mammal, and is losing its dull
grey and becoming more reddish. 
Natural selection is taking place with quite surprising speed.
