    In this chapter, I have described a few models that represent alternatives to Brownian motion, which is still the dominant model of trait evolution used in the literature. These examples really represent the beginnings of a whole set of models that one might fit to biological data. The best applications of this type of approach, I think, are in testing particular biologically motivated hypotheses using comparative data.

    Section 6.9: Footnotes

    1: Pagel's original models were initially focused on discrete characters, but - as he later pointed out - apply equally well to continuous characters.
