Talk:Speciation/to do

(from peer review comments:)
 * A more extensive discussion of the Galapagos would be useful, as it's the best-known example of the phenomenon.
 * A discussion of phylogenetics and the measurement of species coalescence times might be a good expansion.
 * The "observed examples" link to talk.origins is well-researched and useful as an external link, but surely there's a more academic compilation somewhere?

(from Samsara)
 * Speciation by polyploidy
 * better in a separate section, that then also mentions that it does not depend on any degree of spatial isolation
 * Discussion of pre-zygotic vs. post-zygotic isolation
 * Explicit treatment of sexual selection and assortative mating
 * The possible role of punctuated equilibrium, esp. in peripatric speciation
