Common misconception of Evolution, Simplicity, and Primitiveness
Now, evolution is often understood as a ladder of progression – from simpler, basal organisms gradually becoming more complex and sophisticated. This view of evolution is entirely incorrect. Species do not transform into other species. While "simpler" and more ancient lineages of organisms may indeed resemble their ancestors, they are nonetheless derived from common ancestors with their closest (and furthest) relatives. I.e. they do not represent members of a group which have transfigured into something more complex. However, the below ad is very cool – despite the erroneous depiction of evolution. Let's face it, it's really about the pen being able to create and erase. Unwittingly, it does draw out a good point about evolution: throughout evolution, features (I'll say structures for the sake of simplicity, but there's a biiit more going on at the genetic level) are gained AND lost. http://www.buzzfeed.com/ryanhatesthis/this-might-be-the-best-a...
