Have not seen that one before. I find this very interesting, I have several sites on stuff like this, I will look back thru my bookmarks and if I find them I will get back to you with the links.
You do know that these pictures are from a photoshopping contest from a website called worth1000, right?
There’s a mathematical problem in making giants: As length doubles, surface area quadruples and volume multiplies by a factor of eight. Given this, an anatomy which works fine for a six-foot-tall man, doesn’t work for a twelve-foot-tall man; hence a Chihuahua is by necessity a very different dog than a Mastiff.
