Elephant I get, but why newts? Birds and bats would
be great targets for sequencing since they blow the
metabolism/longevity tradeoff so drastically.

Dunno if Michael is working on such a project, but it's already been
done: Nagai, Lin, and Sabour 1995. "Lines of Mice Selected for
Reproductive Longevity", Growth, Development and Aging 59:79-91.
(Michael knows of this and cites it) Seems like a great system to
investigate mechanisms but I'm not aware of any such work. I
hope they've still got the selected lines.

Oooh, oooh - how about temporary habitat shrimp? Nature's already
done the longevity selection for you. (guess what I'm working on
this quarter :-) Those slow-aging island possums could also be a
pre-made model.
