How long have Focus Group and Neighbour Group people been in contact overall?

As far as I know, the Yuhup and the Macuna have been in contact for at least the last 60 years, but it might be longer.

The information given here comes from one Yuhup group in Colombia, currently living in a settlement called Bocas de Ugá (Apaporis River, Departamento de Vaupés). There are other Yuhup groups: one, also in Colombia, located in the Jotabeyá area (Departamento de Vaupés) who are closer with the Macuna and even share settlements. The other, in Brazil, located near the Apaporis river mouth, has no contact at all with Macuna people.
