I read somewhere that manmade boundaries can be clearly identified. They are mostly straight lines on maps. It makes more sense after reading this article. This is the reason why so many African countries have such sharp boundaries. Colony masters divided them amongst themselves, ignoring natural resource division, people and ethnicity of new countries. This has led to so many conflicts among these countries as well. I might be wrong, but I think this happened to middle-east as well.
