George Williams (of the pleiotropy theory) added a refinement: that the early stages of senescence would likely have consequences for individual competitiveness, so he based his theory on the idea that selection against aging was weak but not zero. Crucially, though, the anatomy of this mammal's inner ears closely matches that of modern whales, the main "diagnostic" feature that places … Stone and ivory harpoon tips were found in the blubber of some of the bowhead whales … Gestation is 16-17 months. “It estimated the maximum lifespan of the Pinta Island tortoise to be 120 years old.
