Always interesting reading this sort of stuff Dyslexia - Wikipedia, the free encyclopedia. Humans are such a varied species in so many ways. No doubt that's also true in other species it just alot harder to observe when it's not our selves.
Wikipedia's an interesting and useful source but like all things on the internet care must be taken when using such a source. It's well worth finding a couple of papers or reviews from a respectable journal, which is one thing that wikipedia has going for it the use of references and a bibilography for the more scientific articles.
