english: With many of the same signs appearing in such far-flung places, especially in that 30,000 to 40,000-year range, it's starting to seem increasingly likely that this invention actually traces back to a common point of origin in Africa.
non_english: S obzirom na to da se mnogo istih znakova javlja na tako udaljenim mestima, naročito u tom opsegu od 30 000 do 40 000 godina, počinje da izgleda sve verovatnije da tragovi ovog pronalaska zapravo vode do zajedničkog porekla u Africi.
