I got into a discussion at work (fool me) with a person who turned out to be a IDer who unfortunately is also an aerospace engineer who went on about the evolution of the 4 bar link in the knee. he basically said that a 3 bar or a 2 bar link just won't work and it has to be a 4 bar link. Hence the ID bit ...
Now my background is not in anatomy but rather biochem/molecular biocogy so I really don't have a particular idea on how the knee evolved ....
Anyone know?
To my irritation most of the google links point to ID sites
