Final answer:
The earliest archaeological evidence for language dates back to around 50,000 years ago (~50k BP). The earliest genetic evidence for language dates back to around 150,000 years ago (~150k BP).
Step-by-step explanation:
The earliest archaeological evidence for language dates back to around 50,000 years ago (~50k BP). However, it is important to note that the archaeological record does not provide direct evidence of language, so researchers have to rely on indirect forms of evidence to suggest theories about its emergence. Some indirect evidence includes the development of symbolic language and the production of tools by early hominins.
The earliest genetic evidence for language, on the other hand, dates back to around 150,000 years ago (~150k BP). Genetic studies have shown that certain genetic mutations associated with language are present in modern humans and their closest relatives, such as Neanderthals. These genetic mutations suggest that language may have emerged in our common ancestor.
