An interesting idea. We live short lives because dinosaurs hunted our distant ancestors ...

Read something about this a while back, not convinced there is a fair gap between dinosaurs and modern humans, ancients were reputed to live much longer than modern humans and I feel some other developments have changed our metabolism. Our biggest danger has always been and still is our fellow man, we are not a very tolerant species, we don't just fight for a mate like most creatures, we fight for everything.

Extant avian theropods are mostly K-selected - some petrels have actually switched off telomere exhaustion, making them (very) theoretically immortal - but mesozoic dinosaurs mostly had life fast, die young strategies. Even the giant sauropods were essentially "weed" lifeforms, like the pines that fed them. This might have allowed the dinosaurs to swamp the competition (stem-mammals, crocs) after the Triassic/Jurassic extinction event.
