"It is very likely that within 3000 years (~120 generations) we have all sustained two or more mutations harmful to our intellectual or emotional stability," writes Crabtree in a study published in Trends in Genetics.
By contrast our ancestors would have had highly selective evolutionary pressures on the genome.
"The development of our intellectual abilities and the optimization of thousands of intelligence genes probably occurred in relatively non-verbal, dispersed groups of peoples before our ancestors emerged from Africa," says Crabtree.
Without a well-functioning intellect, our ancestors would not have been able to survive in an environment that required them to constantly to adapt to new dangers. But our modern environment doesn't select against deleterious mutations in the same way, leading to a gradual loss in our emotional and intellectual abilities. To make matters worse, neuroscientists believe that genes involved in brain function are particularly susceptible to mutations.

Yup. Republican politicians who say stupid things tend to reappear after the next election hosting Faux News shows. It's one of those Circle of Life things.

hell, they'll take anyone from any persuasion, as long as the fall is substantial - can you say dick talks out of the side of his mouth morris
Trump: “We had the safest border in the history of our country - or at least recorded history. I guess maybe a thousand years ago it was even better.”
