Is evolution like a well-tuned car that purrs down the road at a steady pace? Or is it more like an aging, rattling jalopy that often lurches forward? The aging jalopy is a handy metaphor for the ...
Testing Macroevolutionary Hypotheses with Cladistic Analysis: Evidence Against Rectangular Evolution
The properties of cladistic data sets from small monophyletic groups (6-12 species) are investigated using computer simulations of macroevolution. Two evolutionary models are simulated: gradualism and ...
This is a preview. Log in through your library . Abstract The question "Does phyletic gradualism or punctuated equilibria describe evolution through geologic time?," is fruitless to pursue, even ...
