The essence of the facts, page-575

Today we find that philology, the comparative study of languages, generally classifies languages into distinct “families.” Among the major “families” listed by modern philologists are: Indo-European, Semitic, Hamitic, African Negro, Sino-Tibetan, Japanese and Korean, Uralic and Altaic, Dravidian and Malayo-Polynesian. However, there are still many languages that defy classification today.
Interestingly, the “parent” language of each major family usually has not been identified. Certainly there is no evidence pointing to any one “parent” language as the source of all the thousands of tongues now spoken. The evidence, instead, points to the many “parent” languages begun at Babel.
