  1. J. C. Vaupel Kleivonn (1995). Phyletic Gradualism Versus Punctuated Equilibria: Why Case Histories Do Not Suffice. Acta Biotheoretica 43 (3).score: 502.5
    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, in order to correctly establish the possible merits of both concepts, the claims of each have to be verified against general evolutionary theory. This is being pointed out herein by analyzing (...)

  2. J. C. Vaupel Klein (1994). Punctuated Equilibria and Phyletic Gradualism: Even Partners Can Be Good Friends. Acta Biotheoretica 42 (1).score: 29.3
    The allegedly alternative theories of Phyletic Gradualism and Punctuated Equilibria are examined as regards the nature of their differences. The explanatory value of both models is determined by establishing their actual connection with reality. It is concluded that they are to be considered complementary rather than mutually exclusive at all levels of infraspecific, specific, and supraspecific evolution. So, in order to be described comprehensively, the pathways of evolution require at least two distinct models, each based on a discrete range of (...)
