PT: What's an example of how astronomy is important for the Bushmen or the Dogon people?

TM: One evening with the Dogons, I went with two old people to look at the stars. I asked them what was the most important constellation for them. They said the Pleiades, a star cluster, which is very important throughout the whole of Africa, actually. The stars are used for planting and agriculture. I asked this guy [for] positions of the stars, and he gave me the rising times and positions at different times of the year. I checked with my laptop, and he was very much correct. To me that proved he knew what he was talking about.
