There are a lot of basic mistakes in this article. It claims that cells haven't changed much in 1.5 billon years, when in fact eukaryotic cells and multicellular life are only 0.5 billon years old. The details of action potentials are wrong too. Those mistakes are just details. But I'm a physicist, so I can't tell if there are more serious mistakes that break the whole argument. Any biologists want to comment?
