That's an old turtle.

"A 176-year-old tortoise believed to be one of the world’s oldest living creatures has died in an Australian zoo.

Senior veterinarian Jon Hanger told the Australian Broadcasting Corp. on Friday that Harriet died of heart failure.

Harriet was long reputed to have been one of three tortoises taken from the Galapagos Islands by Charles Darwin on his historic 1835 voyage aboard the HMS Beagle."

Man! He'd have to wait a long time to see evolution at work in THOSE guys.
