摘要: Many attempts have been made at supporting either one of the allegedly complementary divergence models Phyletic Gradualism (PG) and Punctuated Equilibria (PE) by patterns found in specific fossil sequences. However, assessing each model's connection with reality via such “individual case histories” appears not to constitute a relevant approach. Instead, order correctly establish possible merits both concepts, claims be verified against general evolutionary theory. This is being pointed out herein analyzing cladogenesis level as an example.
