If you like things like megafauna and paleontology, and comics, you may like this Dresden Codak page. The article made me think of it, anyway.

    ‘homo sapiens growth rate and hunting ability almost always led to mass extinctions, with hunting ability being the most important of all parameters’. Big animals are particularly susceptible to extinction

I wonder…intelligence presumably requires a certain level of mass. Does this suggest that any relatively highly intelligent species will likely exterminate any other species large enough to evolve high intelligence?

So, would all planets where life has evolved result in a single sentient species?
