Punctuated vs gradual evolution
WebSep 1, 2024 · The co-occurrence of discrete and catastrophic events in most cancer types actually supports our DPCNE model. Therefore, our model reconciles the conflict between gradual evolution and punctuated evolution, implying that it is not a binary choice and both evolution strategies can be exploited by tumor cells, alternatively or parallelly.
