But SEE didn't evolve from ASL over thousands of years of use by native users. SEE was created in 1972 in an artificial academic setting.
Suppose a group of academicians gathered at Princeton, NJ, and decided that American English was too hard to learn and use. They wanted something that would fit in better with the global economy. So they invented a language that retained some of the American English vocabulary but followed the rules of European Romance languages, such as French. They kept the root verbs but all the endings were changed to fit French grammar rules. And so forth . . .
The academic group pushed hard to get this new "language" taught in all the public schools. All new textbooks included the new "language", and all news media had to use the new "language." They promoted the new "language" as a more advanced kind of English, and spoke patronizingly of the "old" clumsy English. Instructor training and curriculum for the new "language" became a big business. Native users were told that the academics knew what was "better" for them....
That's the difference between a language evolving, and a pseudo-language being invented.
