Big question today: Were our ancestors smarter than we are?

Not talking about intelligence, but just plain ole smarts.

Reason I ask: Just got back from a trip involving air travel. Day after I got back I read this in my Sunday paper that the TSA folks just shared that 4,239 firearms were found in carry-on bags coming through airport checkpoints in the U.S. last year, an increase of about 7% over the number found in 2017. And nearly 9 out of every 10 of those firearms were loaded and more than a third had a round chambered!!!

Factoids like that do make me wonder. Yah, our ancestors went over Niagara Falls in barrels but that never hurt anybody but them.
