Talking about rabbits to my friend here brought up an interesting anecdote. His friend somewhere in the Utah had a male rabbit. His mother in law or somebody had a female one. They wanted to experiment with the two rabbits during some family vacation. They put them on the same table - the male rabbit looked to the left and the right for a second and immediately pounced on the female rabbit for mating. Just a few seconds elapsed before the family people pulled them apart - they didn't know quite what happened, but a month later or so, they were blessed with about 7 baby rabbits ;) They were apparently quite clever in selling them off to kids and other families in the neighborhood.
Looks like humans have a reasonably long life time considering their size. Elephants live longer than mice and rats which have a very short life span. The housefly has only 3 days on this planet. It is said that the bigger the animal is, the longer is its lifespan. But of course there are obvious exceptions. Some parrots live upto 150 years. Tortoises live for centuries. I can't believe this evolution thing. Even though it may have happened over millions of years, looking at the number of species on this planet, it seems highly improbable. May be I have to look into the theory of intelligent design ;)
