If humans were to leave Earth for a while, what would be the next dominant species?

Probably the monkeys, they're the same as we are. Though lions and or other carnivores can domin8

1.6 million ants per person.

Ants> everything

Rats/Mice until all of our rubbish was gone. Then there wouldn't be a dominant species, since humans are the only species that really "dominates". It would just go back to the food chain.

Another interesting thing is the fact that billions and billions of livestock would die since there wouldn't be any food for them to eat.

Some sort of insect. There's a shit ton of ants.

It explains it

if octopuses were to develop a means of communication I think they'd be set.

they're pretty smart already

Depends on what happens to the earth. If humans were forced to leave for example by a nuclear war the dominant species would probably be cockroaches.

Obviously apes.


Has no one watched Planet of the apes?

Beetles,Cockroaches and LadyBirds, they're almost from the same kind (Almost)
