If a body raises its own offspring or spends time with another organism it has a chance to transmit knowledge. These can be hard-coded references to locations sent identities and other information. The information or knowledge is stored in the new body with a tag referencing its source that is who the teacher was that could mean all this lineages this way that are separate from genetic lineage period for example if you adopt a child or take a spouse or partner or simply make a friend or if you extract knowledge under duress all these cases will cause a teacher tag to be attached to the knowledge which you can then spread and the teacher tag lineage gets added as it's passed on.
