Wherever we look at the living biota … discontinuities are…
“Wherever we look at the living biota … discontinuities are overwhelmingly frequent…The discontinuities are even more striking in the fossil record. New species usually appear in the fossil record suddenly, not connected with their ancestors by a series of intermediates.”
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Evolutionary change often occurs in rapid bursts, leaving gaps in the fossil record rather than a smooth series of intermediates.
In simple terms: Evolution can happen in jumps, not always gradually.
Key Takeaway
Expect sudden changes in complex systems.
