David, This article was to show folks the reality of convergent evolution. The snakes were only an example of this process. I could have used hundreds of other examples, but the point is that humans have been able to create a technology from very humble beginnings by moving into the tool making/using niche. Can't we speculate that another species(monotremes?) could also have taken up tool making/using and after a few million years were not only able to accomplish an advanced technology, but began to look similar to us. Actually, we look like them, since they evolved first. It's the niche that determines this. I don't have any problems with the rest of your interesting post. Listen to 'Strange Days...
