Random bits #10
A bunch of interesting papers have come out recently that I'd like to comment on, but I keep getting farther and farther and farther behind... so here's a quick summary of a few articles of note: This week's PNAS has a series of articles on australopith diets as inferred from teeth - and this isn't your usual attempt at correlating tooth morphology to diet. These papers are using (or summarizing) isotope methods to figure out what australopiths (and other hominids) ate. Because certain plants have different carbon isotope ratios than others, and those ratios can still be detected in tooth enamel. What do we find? Lots of variation both geographically and taxonomically. Really interesting stuff, and it starts with this summary (which has links to the other articles in the series): Stable carbon isotopes and human evolution Over in Answers Research Journal , there's a new article by Michael Brandt. That name is probably unfamilia...
