Is the person you just met unable to make small talk? Did she seem befuddled when you asked her if she were from the middle west? Did the fellow drinking mineral water near the bar express confusion when you asked him how the Lakers were doing? The answer is obvious, according to a new book from Oxford University Press. Although these people look human, maybe they are not.
The Ruins of Evolution proposes that given certain demands as far as mobility, cognition, etc., it is likely that extraterrestrials evolving on other worlds, probably developed to look like us. Here’s an article on the subject: http://www.independent.co.uk/news/science/forget-little-green-men–aliens-will-look-like-humans-says-cambridge-university-evolution-expert-10358164.html
I find the idea plain silly and an example of human arrogance. Just because we evolved certain ways does not mean that everything intelligent in the universe had to evolve the same way. In fact, I’m sure there are lots of planets we would deem uninhabitable that might support life. Maybe not life as we know it, but certainly intelligent life.
On the other hand, if you would like an example of aliens who do resemble us as well as some that definitely would make your skin crawl, read my new science fiction novel, Alien Love.
