Which continent has the greatest number of language groups?

The continent with the greatest number of language groups is Africa.

Here's why:

* Linguistic Diversity: Africa is home to a remarkable diversity of languages, with estimates ranging from 1,500 to 2,100 distinct languages.

* Historical Factors: Africa's long history, diverse cultures, and geographical isolation have contributed to the development of a wide array of languages.

* Language Families: Africa is home to numerous language families, including Afro-Asiatic, Niger-Congo, Nilo-Saharan, and Khoisan, each with numerous branches and languages.

While other continents like Asia and Oceania also boast significant linguistic diversity, Africa's sheer number of language groups puts it at the top.
