re: The sex differentiation of animals go far beyond you imagine on evolutionary line

I'm sorry for this off-topic question. I'm also an English learner, so it'd be nice if you could help with the language so that I can get the point.

I would have written: The sex differentiation of animals go far beyond you can imagine on the evolutionary line.Or, rather better: The sex differentiation of animals happened far long ago on the evolutionary line. Does my way match what you had in my mind?
