In biology, convergent evolution describes the process whereby different animals acquire similar traits in separate lineages.

Two people can arrive at the same solution to a problem, or invent something, without the influence of each other.

Is there a word (or phrase) that sums up the coincidence of 'arriving independently' at the same solution? A convergent solution? Synchronicity?

There are a number of articles online that call it simultaneous invention or simultaneous discovery:

This phenomenon of simultaneous discovery—what science historians call “multiples”—turns out to be extremely common.

Wikipedia calls it multiple discovery:

The concept of multiple discovery is the hypothesis that most scientific discoveries and inventions are made independently and more or less simultaneously by multiple scientists and inventors. The concept of multiple discovery opposes a traditional view—the "heroic theory" of invention and discovery.

One possible mechanism for this is called bunching phenomena. rjlipton.wordpress.com/2011/03/19/… – ThinkingStiff Dec 12 '11 at 4:52
That was perhaps for want of a better expression. I just cannot see how simultaneous invention, simultaneous discovery or multiple discovery can preclude the possible meaning of "someone inventing/ discovering several things at a time", rather than as intended. – Kris Dec 12 '11 at 11:36
