Interesting answers from both doma and orda.
I sometimes wonder what is (or might be) captured, recorded and transferred via DNA - along the lines of orda. There are some memories that almost must be transferred via DNA eg multi-generational migration patterns in the Monarch butterfly life-cycle. Someone's speculation, anyway. I noticed our Welsh speaker actually had a Welsh name, suggesting a likely ancestry.
And I have also contemplated doma's idea. I'm not sure where original thoughts come from and whether they are necessarily generated internally.
