Is Evolution Speeding Up?

That’s the premise behind some new work recently done.  Of course, I should point out a flaw in their work, where they assume that the mutations they find are beneficial….

Over time, chromosomes randomly break and recombine to create new sequences of SNPs along the chromosome. A large number of identical SNPs means the mutation is advantageous and new.

[emphasis mine]

It’s trivially true that more humans means more mutations, but does that truly equate with faster evolution?  No.  The sticking point is the flaw that they assume beneficial mutations.  We know that most mutations are not beneficial.  That we don’t see an end product result of more evolved humans speaks louder than their failed assumptions.
