This is a huge aspect. We've already got lots of precedent of splits between nomadic vs. agricultural societies. I think we would naturally group ourselves into 'travelers' and 'settlers', with a small amount of migration between the two-- and eventually in the long run, species differentiation.
- rbanffy 8y agoWith small populations isolated during the centuries between stops, differentiation will be very fast and could happen within a single longer trip. There are only 10,000 years between wolf and poodle. In order to avoid it, the groups could start the journey with a set of frozen eggs (or static genomes in whatever medium they find convenient) to be reinserted into the population along the trips, as well as extensive genetic matching between the living populations to ensure a viable long-term gene pool. And, of course, it's not unreasonable to expect some groups to engage in active eugenics and direct their evolution so they are better suited to their way of live - nomadic or settler.
