PPT-3.3 Evolution on Adaptive Landscapes

Stevan J Arnold Department of Integrative Biology Oregon State University Thesis Models for adaptive radiation can be constructed with quantitative genetic parameters The use of quantitative genetic parameters allows us to crosscheck with the empirical literature on inheritance selection and population size.

I often say that when you can measure what you are speaking about and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the state of Science, whatever the matter may be..
