I found this article rather fascinating mostly because I’ve long thought that “our technological and medical advances have removed most of the selection pressures acting upon us”. That such is not the case makes for interesting possibilities.
Human evolution is speeding up. Around 40,000 years ago our genes began to evolve much faster. By 5000 years ago they were evolving 30 to 40 times faster than ever before and it seems highly likely that we continue to evolve at this super speed today.
Our population explosion and rapidly changing lifestyles seem to be the drivers of this acceleration, the discovery of which contradicts the widely held notion that our technological and medical advances have removed most of the selection pressures acting upon us.
