Well, strictly speaking, Romance languages are not the evolution of Latin - each is a mix of (the Vulgar) Latin and a local language. For example, French has been heavily influenced by Frankish, so much so, in fact, that English, not even being a Romance language, seems closer to Latin than French does - simply because it imported so many words directly from Latin. (The closest example of a continuous and mostly unadulterated evolution of a now dead language into a modern one is Greek.)
