"Ontogeny and Phylogeny" by S.J. Gould

Available online (free!), but I'm reading the hard-copy.I've just started, but it looks like a really promising avenue for understanding heterochrony and to learn about Gould's hypothesis of neoteny governing development of the human brain.I tried skipping to the neoteny section, but I needed the heterochrony sections. I tried skipping to the heterochrony sections, but I needed the history sections. So now I'm all the way back, and managed to get "forward" to page 40.I want to have this thread to post some thoughts, especially when I finish. My question for now is, is this book still good, or is it outdated? It's approaching 30 years old now.Any comments on the book or suggestions as a whole would be appreciated!

Hey Brad,How's it going on this? Made much progress?I haven't gone back to Gladyshev's papers yet, but I think I'm ready to do so. I've done some refreshers in electricity and magnetism, special relativity, and some good quantum. Plus the biological background stuff I was working on before.I'd really be pleased if you could talk about the usefulness of defining a "biological time," and what it means for that time to be discontinuous. Do you mean discontinuous as compared to historical time? I assume not, but I cannot come up with anything else that makes sense to me. And I cannot escape me enough to find another possible solution.Thanks,
Ben
