Sub-Saharan Africa is the only family that has click sounds.
The Americas
We know very little about the languages of the Americas, and nothing concrete.
It is thought that there are three language families to be found there, caused by three main waves of migration, but we have no conclusive evidence as of yet.
Certainly there are some of the Eskimo families, which are distinct from the Amerindian families.
The Amerindian languages are spoken by 11,000,000 people in South America. We know of 600 Amerindian languages, although data is limited. Quecha is the principal language; the language of the Inca Empire.
The most dominant typological feature is their SOV word order.
