<< Numerous evolutionary mechanisms have been proposed for generating rapid
diversification, including key innovations (eyesight, predation, planktivory,
hard skeletons, etc.) and environmental factors (global warming, increased
oxygen levels, etc.). Conversely, various factors have been suggested as
constraining later evolution, including the filling of niches and increased
genomic integration and stability.
The objection to all such mechanism is that they comprise what Walter Remine
calls a smorgasbord of explanations, from which one selects the one that
seems most plausible. Are you really satisfied that after you list all these
possible mechanisms, plus the etc., that you really know anything more than
you knew before? These are really only hypotheses at best that still need to
be tested. Just listing them is no more than the first step, like
brainstorming. How does one test them?
