ok,
show something real meaningful like from English to Chinese?
what's the matter?
having trouble withthe inbetweens?
I'm glad this was brought up. Language, and the way it changes over time is much better analogy for evolution then Font Color.
People are constantly inventing new words in language, while lesser used words fall out of use. Some of the new words die out, others find a solid place in the language. This is fairly similar to mutations within a species population.
Speciation (The point at which a population of animals differs enough from a previously similar population of animals, that they can not interbreed, and are no longer classified as the same species.) Is VERY similar to how subtle changes in language over time lead to two groups unable to communicate.
For instance, here is a bit of Old English.
"Fæder ūre þū þe eart on heofonum"
Contrasted, here is fairly direct translation to Modern English
"Father of ours, thou who art in heaven"
Another great example is Latin, which broke into several languages after the fall of the Roman Empire. Languages such as Italian, French, and Spanish.
However, at no point did anyone simply stop speaking Latin, then snap to French. The change was gradual. Accents start to vary in the population, words are pronounced slightly differently each generation, new words replace old ones, or old words take on new meaning entirely. Soon two populations who 400 years ago each spoke Latin, can't communicate at all.
This brings me to your question Merlin, as to how English could 'evolve' to Chinese. Keeping the Analogy going, this is just as impossible as explaining how a Cat evolved into a Dog. Both Languages are just the most recent variations, in a long, long list of variation. Though these language may share a common ancestor, they are far, far removed from each other now.
