Apes, Monkeys, or any type of primate.

If you want to make jokes, makes them at least half decent, and post them with something that actually contributes to the thread.
If you want to use facts, do some research before you post your claims, because honestly, there's so much wrongness happening here.

Otherwise, we'll just have to close the thread.

Apes, then they might evolve into humans, if that's the theory believe.

what you guys are failing to mention is the fact that no other species is able to adapt to other environments like Humans are. I would say that each climate would develop its own "superior species" and we can't really compare a dolfin against a chimpanzee evenly because they are best suited to their environment, however not nearly capable enough to survive in a different environment.

Once monkeys can conquer the seas in boats or dolphins conquer the land with who knows what a new dominant species can't be told.

Raccoons, they have thumbs and fingers and will be using our guns after were gone to hunt dolphin and monkey savages. They're already here driving our cars, changing the channel, texting and posting on Facebook.

The octopus. Now just hear me out. The octopus has shown significant prediction capabilities. This intelligence is the one that makes people special. This is the human edge. people can use the environment to determine cause and effect. It also leads to having imagination.

Imagination is required for problem solving. The octopus is very a imaginative and able problem solver. It may be a long way off from playing Chess but I would say it is the closest non-ape to it. I did not exclude them from this projection.

Apes all across the world are struggling. If only we could teach them to read they would only be a hundred years or so from joining scociety. However I doubt that what ever takes humans off the map will spare the other apes. I am going with the mass flooding from climate change from pollution.

As we all dump tons of CO2 into the atmosphere it becomes dencer and traps more gasses and heat. This heats up the ice caps and they collaps completely, raising sea level by manny meters. As the oceans become deeper and colder the octopi moves onto the swampy contental shelf.

Now imagine your entire nieghborhood is underwater. Small fish would thrive in houses and bigger ones in the street. Now imagine the octopus in that enviroment. The crocodile would be its biggest threat, that and medium sized sharks. Other than that it would be free to crack open suburban homes like cans of fish. The would be the dominant lifeform in the area. Now here is we streach our sci-fi legs.

If we get very lucky, they will get so good at it that they get board. Manby they will wonder about us. Maybe they already do. They might develope language and recreation. I think that that would last for a while, at least until the oceans cool the now CO2 rich atmosphere and it settles into the oceans, freezing them and causing an ice age; but hey, they could adapt.

Aren't algae already the dominant species?

Other than them, I'd like to think dolphins would take over once they perfect their overland-travel technology.

Of course, it would be interesting to see what would happen with octopi, since their theorised intelligence would have evolved completely separately to ours, unlike the dolphins. I can imagine underwater colonies of octopi easily enough.

I tend to doubt that any insect could take over, mostly because their ability to adapt to change in a single generation (basically without breeding and therefore natural selection having an effect) is generally quite poor.
