Humans will evolve into whatever nature needs us to be to survive. If global temperatures keeps rising and our ice sheets keep melting and raising the water table, we might morph into Mermans and live in the ocean. Just saying... lol!
Improvements and adaptations are two different things I guess... perhaps it was just an adaptation to asteroid strikes, global flooding and a dearth of cows...
It is not an improvement, unless humans (millions of years in the future) evolved to live in a different environment. But I do know that the author of the article is right - evolution doesn't work that way.
A mere tittle of complaint from me would be that evolving away from a voice-box and manipulative fingers would not be at all likely for success of offspring.
