We're the species currently dominating a niche.

Calling anything the 'pinnacle' of evolution implies some sort of progress towards perfection. Evolution does not work that way.

Says a member of the only race in 2 billion years that CAN argue about it...

You misunderstand how evolution works. It is not a progression towards perfection.

You're conflating biological evolution with creationism / 'intelligent design'.

Any anyway, how do you explain going from single-celled creatures to working organisms with a trillion cells? Darwin claims species are driven by their environment to better compete - is that not something like perfecting them?

No. Perfection implies a scale with a top end.

We compete for spaces in a niche, we don't compete to be all round "better".

No, I'm being funny. Somebody else is using words like "conflating".
