“If new species arise very rapidly in small, peripherally isolated local populations, then the great expectation of insensibly graded fossil sequences is a chimera. A new species does not evolve in the area of its ancestors; it does not arise from the slow transformation of all its forbears. co-author with Niles Eldridge”
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Rapid speciation in isolated groups challenges the idea of smooth, gradual fossil records; new species appear abruptly.
In simple terms: New species can appear quickly, not always slowly.
