Western, Central and Southern Europe had indigenous dark-skinned inhabitants until the Early Neolithic era (c. 8,500 years ago). Scandinavia Eastern Europe, roughly to the east of Lithuania and Romania, was already inhabited by light-skinned native people since the Mesolithic period at least (c. 10,000–15,000 years ago).
The large majority of those dark-skinned aboriginals probably had brown skin, brown wavy hair and blue or green eyes, and they were an offshoot of earlier Paleolithic West Eurasians, or rather, more likely, several distinct West Eurasian groups that blended to form a new European population by the Late Paleolithic era (c. 15,000 years ago) .
