The equid family contains only one single extant genus, Equus, including seven living species grouped into horses on the hand and zebras asses other. In contrast, equine fossil record shows that an extraordinarily richer diversity existed in past provides multiple examples of a highly dynamic evolution punctuated by several waves explosive radiations extinctions, cross-continental migrations, l...
Human language, over its evolutionary history, has emerged as one of the fundamental defining characteristic of the modern man. However, this milestone evolutionary process through natural selection has not left any ’linguistic fossils’ that may enable us to trace back the actual course of development of language and its establishment in human societies.
