Interesting Guardian article (picked up from a paper in Science, to which I don't have access). ***** Guardian link: https://www.theguardian.com/science...ates-appearance-of-humans-genetic-study-finds Science link: http://science.sciencemag.org/content/353/6297/380 ***** The perspective is evolutionary but there are obvious implications for health. Whenever I read this kind of thing, I wonder why we aren't routinely doing metagenomic gut profiles on neonates. The current testing might be imperfect, and the future uses uncertain, but there seems little doubt that precise manipulation of the microbiome will be a big part of future medicine. Wouldn't it be sensible to start getting baseline profiles for newborns right now? Is anyone already doing this?
