This issue looks at human migrations, both modern and ancient. The feature examines the science of human migrations, with both Pueblo people in the Southwest and archeologists working together at Mesa Verde.

Movement is fundamental to humans, and just one way that we’re still connected to the natural world.

I have been very unhappy with the liberal bias that this publication has developed over the last few years, but seeing the F-word used sealed it for me: You…
