And that’s only up to 1066!
I’ve been trying to understand this discussion from an English perspective. It’s interesting but, as you say, very complex, and without mass DNA screening it’s impossible to determine which of us has ancestry from which group. And I find it hard to see how it’s relevant to iNaturalist data at the observation level.
If I wanted to document, for example, the biodiversity of a village that was forcibly “deserted” to make way for sheep farming, I would create a place and a collection project for it. But unless there were detailed historical records of biodiversity and genealogy it wouldn’t be very useful.
I understand of course that this may be trivial when compared with the scale of injustice and oppression faced by whole indigenous/aboriginal peoples in colonised countries, but it’s the closest analogy I can relate to, and I’m struggling to see how it’s relevant to iNaturalist as a repository of observation data where location is simply an intersection of latitude and longitude (although that in itself is not a culturally neutral construct).
