Latin was a language which predominant order was Subject-Object-Verb, as in the example proverb Errare Humanum Est

So, why all its modern descendents are predominantly Subject-Verb-Object order? Or are there some that I don't which order is not that?

I can assert the SVO order on Portuguese, Spanish, Catalan, French, Italian and Romanian, which are the most represented in Europe. May be there is some not so popular language that is not SVO.
