Similarity among organisms is one of the evidences used in support of common descent; however, special creationists would have it that this is evidence instead of a common designer. It has always struck me that this common designer argument was little more than an ad hoc, knee jerk reaction intended to explain away organismal similarity rather than to simply explain it. So I thought I would introduce this challenge.
Below are six inventions (designs) created by two independent inventors. Assuming that there is something to the common designer argument beyond some Pavlovian anti-evolutionary response, it should be possible to classify these objects according to who invented them. Note that I'm not looking for names, either of the inventions or the inventors. I'm only looking to see whether these can be grouped correctly, and for an explanation as to the methodology involved (presumably, some appeal to similarity in design).
I will display these images in two separate posts, given there's a limit of pictures per post.
