Gregory Clark's work A Farewell to Alms discusses human micro-evolution taking place within the last few centuries, but is highly controversial (or so I hear).

To almost anyone who knows much about evolutionary biology its not controvertial but positively laughable.

Cites?

Yeah, that's like saying you could domesticate foxes in less than a human generation, or have adult lactose tolerance increase from 0% to 99.x% in some populations in under 4,000 years. Does this guy think we're completely credulous?

The traits that I am aware of that show strong evolution all have had thousands of years to be selected for, like lactose tolerance in people descended from herders, resistance to high altitude with a hemoglobin change in Tibet, apparent sexual selection for blue eyes in Europeans and thick hair in East Asians, smaller stature in basically all long-term agriculturalist populations...

-Cellbioguy, elsewhere in thread.

I suspect you've misidentified his contention here; he clearly doesn't seem to think humans haven't evolved within the Holocene.
