I get that humans are wiping out a lot of less capable species. This will turn out to be wrong if humans are themselves wiped out. But from an evolutionary sense, this is a pretty clear cut case; humans are wiping out everything else because we're so powerful. We out compete everything.

And before you assume that's bad, don't forget that evolution makes organisms that do that. It's a core part of the cycle of evolution. I gather the first single celled plants wiped out a lot of other stuff with their oxygen production. Now, the trees grow tall so they can wipe out other plants who can't cut it. In the process the trees are littering their tree bits all over the place. You can barely see 100m in most parts of the world through all the tree crap everywhere. I've been to forests where you cant even touch the ground; it's just like 4 ft of old logs that aren't decaying fast enough (dry forests do this). To trees all that tree crap is trash and it even kills baby trees. To us humans, it's beautiful. And when we pour a bunch of concrete and steel all over, maybe it's trash, or maybe it's beautiful in a different way. I'm just saying 'nature' includes us and the stuff we make. We took over this planet. For better or worse it's a people planet now. We'll see what happens after people (e.g. gen-eng driven specation), but it might be that this is already nice in a way we just don't find 'natural' or 'normal' yet and the next one will also be nice in it's own way that's different from the past.
