The things listed are kind of old... this discussion has been going on for a while. Goldfish and tit for tat, fish and tool use, none of it is really new... so the implication that we're just getting to it isn't quite accurate, and the article didn't even mention what little actually is unique to humans. If you want an interesting talk about "uniqueness" Robert Sapolsky has one from a few years back that has been highlighted on ted, but I feel like the way it is approached in the article implies it is new, and it is not.

One thing that is not correct is that humans are unique in sex not being used solely for reproduction, bonobos are very reliant on sex for social purposes.
