USE IT AND LOSE IT?


USE IT AND LOSE IT?

Some species heartbeat rate averages and lifespans are shown in the table below.

during lifespan x109

Hummingbird 1200 3.5 2.2
Human 60 70 2.2
African elephant 30 70 1.1
Bowhead whale 200 10 1.1

In his book: Scale, Geoffrey West hypothesises that animals live for about 1.2 billion heartbeats, whatever their size, ranging from hamsters to whales. Is there an evolutionary process, or any other process, that could explain this similarity? Could heartbeat conservation cause longevity? Please comment here:
