I think it's helpful to keep in mind, when deciding on our "individual" takeaways from this article, that our DNA requires nothing more of us than that we stay alive long enough to reproduce and pass it along... The earliest humans likely ate whatever was immediately available to stay alive...some survived doing that and they became your ancestors...some died doing that, their DNA with them... If you doubt that just observe babies when they first become ambulatory (start crawling), and come to your own conclusions--babies put a great number of things into their mouths to "try it out"... We think about past humans, and ponder the dietary choices the fossil record indicates they appear to have made... Is a diet that kept them alive long enough to reproduce a diet that has the potential to keep us feeling well into our 30s-50s, or to keep us alive well into our 60s-90s...?
