Thanks a bunch to Mr. Rob Sheppe for sending along a link to a recent article in New Scientist about a prediction that in the future women will be shorter, plumper and have better tickers than they do now. The prediction was made by a Yale evolutionary biologist named Stephen Stearns, who looked at medical histories from what is arguably the most intensive and sweeping study every carried out in the history of the whole wide world, the Framingham Heart Study.
Back in 1948, a very clever person named Dr. Thomas Dawber thought it might be a good idea to begin a study that followed the residents of a single town in Massachusetts called Framingham. The extensive longitudinal study has been ongoing since then and it's yielded a wealth of information about things like cardiovascular disease, smoking habits, dementia, hearing disorders and, now, a snapshot of evolution at work.
