From the article link below. Interesting.
"Our evolutionary history shows that many key adaptations – not just intelligence, but complex animals, complex cells, photosynthesis, and life itself – were unique, one-off events, and therefore highly improbable."
"Surprisingly, many critical events in our evolutionary history are unique and, probably, improbable."
"There are places where evolution repeats, and places where it doesn’t. If we only look for convergence, it creates confirmation bias. Convergence seems to be the rule, and our evolution looks probable. But when you look for non-convergence, it’s everywhere, and critical, complex adaptations seem to be the least repeatable, and therefore improbable."
