Steampunk, Space and Aliens

[Gef]

It's not African, but I'd give natives of one of the two other moons telecom, natural radio, if the humans haven't invented it yet, and brainstorm more scientifically plausible capabilities that would seem like magic to humans, maybe a "curse" carried by a parasite.

How close genetically are the different biomes? Independently evolved, or did life start on one and colonize the others in waves, maybe because of vulcanism? Were the three moons actually one big moon at some point?
