I poked around looking for Wolfram's sources and found their WordData Source Information page which includes a link to:
Ward, G. "Moby Hyphenator." 2000.
The hyphenator is available online and, after downloading it, I found this:
This is likely the the source of the hyphenation used in the Wolfram search. The Moby Hyphenator page didn't have anything noting sources but I was able to find a Wikipedia article on the Moby Project:
The Moby Project is a collection of public-domain lexical resources. It was created by Grady Ward. The resources were dedicated to the public domain, and are now mirrored at Project Gutenberg. As of 2007, it contains the largest free phonetic database, with 177,267 words and corresponding pronunciation.
Which is certainly awesome. The article specifically notes the Moby Hyphenator II as a feature. They also included a link to the Moby Project homepage but it, again, includes no references or sources.
Therefore, I was unable to track this particular hyphenation further. Wolfram got it from the Moby Project; the Moby Project didn't say where the hyphenation came from.
As for the hyphenation itself, the word evolve is typically hyphenated as such:
My dictionary lists evolution as such:
|ˌevəˈloō sh ən|
If, however, you were to pronounce evolution akin to evolve it would make sense to hyphenate it the same way:
|iˈvə loō sh ən|
I checked to see if the Moby Project also has a pronunciation list thinking that, perhaps, it was doing this. It lists these pronunciations:
Transcribing the notation, we find that evolve is entered as
ih-valv and evolution is
ehvə-looshən. So that doesn't help explain the hyphenation either.
Therefore, I highly recommend using what current dictionaries have entered (
ev·o·lu·tion) and disregarding Wolfram's output.
