If humans didn't exist, what would Earth's dominant species be?

Lions.. They were the second most widespread species of mammal besides humans They migrated to Europe, Asia and even North America millions of years before humans did. In fact, as late as the end of the last ice age, they were still found in Europe and North America. The American subspecies of the lion became extinct along with other large mammals at the end of the last ice age And their range has shrunk even further because they were hunted and eliminated by humans in parts of Asia Therefore if humans did not exist, the lion may have continued to dominate In Africa, the lion population has shrunk because of hunting and poisoning by humans

There wouldn't be a single dominant species anymore.

The dominant species has been a marine cyanobacterium for the past two and a half billion years or so, and I don't see that changing, ever.

It would have been Elephantidae (elephants and mammoths).

Probably the same as now; ants.

That would be hard to say since humans have effected the earth for so long.
