My friend and fellow science writer Sarah Zielinski has a nice blog over at the Smithsonian magazine website, Surprising Science – today’s post is about how people used to argue against extinction the way they argue against evolution today. The Earth was the way God created it 6,000 years ago, and that’s that, they said. Here’s that blog post. Check out the other recent posts, too – she’s got some nice stuff there, from whether climate change caused the downfall of Angkor to a collection of embarrassingly bad NASA posters.
