humans began to exhibit evidence of behavioral modernity at least by about 100-70,000 years ago and (according to recent evidence) as far back as around 300,000 years ago, in the middle stone age, (with some features of behavioral modernity possibly beginning earlier, and possibly in parallel with evolutionary brain globularization in h. sapiens).
