“The Biological Clock Isn’t Going To Be Around Forever”

Anthropologist Cadell Last thinks we’re on the cusp of a major evolutionary change, one in which humans would be radically different by 2050. I think his ideas are sound but his math far too aggressive. From Christina Sterbenz at Business Insider:

“Humans already dedicate the most time and energy toward nurturing offspring of any primate species, and this pattern is becoming only more extreme.

‘Human life history throughout our species evolution can be thought of as one long trend towards delayed sexual maturation and biological reproduction (i.e., from ‘living fast and dying young’ to ‘living slow and dying old’),’ Last writes.

While physical needs fueled previous evolutionary changes, cultural and technological innovations will drive the next shift, which has been accelerating since the Industrial Revolution.

Simply said, humans need more time to develop to take advantage of our complex world.

Considering recent advancements like in-vitro fertilization, egg-freezing, and even adoption, the mechanics of biological reproduction have radically changed. ‘The biological clock isn’t going to be around forever,’ Last says — or at least, people can turn it off or ignore it for a while.

Today, and even more so in the future, the success of individual and collective human life depends on knowledge and economic prosperity. Passing on new and important ideas to the next generation involves a process called cultural reproduction, which redirects time and energy toward cultural activities, as opposed to biological reproduction.”
