In any case, regardless of how well the Bering land bridge theory aligns with the archaeological and genetic record, and regardless of how broadly it is accepted within the scientific community, it has become something of an embarrassment, both because some non-Indigenous people have warped its meaning and because many other people have questioned not just the validity but also the motivations underlying it
I feel like theories about the past can all be laughed at. We hear people's ideas/theories from the past and they will either be super accurate or really wrong. But, it should be kept in mind that it is difficult to be right about something when it is just a theory based off little evidence to begin with. Theories should be questioned in order to grow - people need to remain curious and help search for the answer.
