In the long history of humankind (and animal kind, too) those who learned to collaborate and improvise most effectively have prevailed.
Supposedly Darwin, Descent of Man
A look down the intertubes for the source of this quotation led straight to: six things Darwin never said.
For humans, being able to collaborate and improvise is a good fit for resilience in stressed times, if not necessarily for “prevailing” over anything. Children who’ve got this down are surely off to a good start in life.
Not all creatures fit the template, though. Ants and bees appear to be slaves to collaboration. Adult grizzlies, tigers and golden eagles seem to shun it. Neither of those extremes offers a model for us lot, how we could or should live.
