From RD (Reply #1 above):

If any other creature did develop human-level intelligence Id bet against it being a cold blooded reptile or a vegetarian : big brains are power hungry

It takes a lot of energy to run the brain. Even though it weighs only about 2% of our body weight, it uses about 20% of our blood supply and 20% of our energy

That is unexpected good news! It seems to mean that I could use a few extra sudoku a day as a slimming programme!

;D

There is currently no other form of life on the planet that is so destructive to all other life and the very planet we live on.  If something did replace us I hope they learn from our mistakes as we are generally not interested.

It took about 10 million years for humans to evolve from monkeys, or 65 million years from the demise of the dinosaurs to the rise of humanity.

If something was to wipe out all humans (without destroying all we've built, or the entire animal kingdom), one might expect that it would take at least about 10 million years for us to be replaced.  It is doubtful that much will remain to tell the future of our trials and tribulations.

There is nothing innately humane about the animal kingdom.  Much of it is eat or be eaten.

Would a future dominant species be vegetarian, carnivorous, or omnivorous?
