Punctuated equilibria and phyletic gradualism: even partners
can be good friends. Acta Biotheoretica 42: 15-48
Abstract:
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 real phenomena. [Phyletic Gradualism; Punctuated
Equilibria; evolutionary theories; divergence models; additive speciation;
microevolution; macroevolution; anagenesis]
With 134 (I counted them) references to literature about the subject
of which an incredible lot about actual data (including ofcourse fossil-data).
Yes, it's someone from our institute, but it's exactly what you are
looking for. Hope this helps.
