As our evolution slows and industrialization and technology accelerates, a growing body of research suggests that human biology is struggling to keep pace. Many of the chronic stress-related health issues we face today aren’t personal failings or modern inconveniences – they’re the predictable…
A one time random die off of the population is too small of a time scale, likely. While it is possible for mutations to occur that don’t confer survival advantage, those likely get mixed and blended out of the gene pool. Evolution requires traits that provide sustained advantages to emerge over long periods of time and for those without those traits to fail to reproduce.
