Just one example listed is overimitation, how children copies unnecessary steps while chimps did not. The middle post also lists other points for that case.

What about the middle link?

Looks to be a lot of hot air from somebody with an eccentric pov.

Humans have many defects. Look around you.

Not any defects from an evolutionary standpoint. That's really what matters, here.

Can't tell if that's sarcasm or not. But are you agreeing with the second link then?

Duh: Of course we are and so is all other life. I have heard that if we have any "flaw" it's that we are too successful. Human are more effective than other forms of life and that could be our undoing .

Human are more effective than other forms of life and that could be our undoing .Maybe. Being effective is a double-edged sword, but even harmful activity can have some adaptive benefit far down the road. The reverse can happen as well.
