Reindeer gained UV vision after moving to the Arctic - life - 27 May 2011
Interesting article about environmental adaptation. The article is also important on a different level - it shows a situation in which evolutionary developments lead to advantages for a particular species; an example of evolution and adaptation that has nothing to do with humans and apes. Unless you are absolutely set on believing that everything that ever existed or will exist was (or will be, I suppose) created at that moment in its entirety by a supreme being, the article provides a glimpse of how adaptation and evolution are related concepts.
