I’d just arrived in Madagascar for the first time. I was with the foremost expert on the primates called lemurs, trying to pay attention. I had everything to learn. We’d just gotten there on the ship National Geographic Orion, courtesy of Lindblad Expeditions.

You start to see right away that the problems are the usual: poverty, ignorance, the need to eat. (We soon met Dr. Garth Cripps who described the innovative programs of Blue Ventures, helping local people set up protected areas on depleted reefs and gain access to family planning.)

They evolved there from a pre-monkey, pre-lemur “prosimian” primate ancestor who probably survived a trip across the Mozambique Channel in the hollow of a tree washed out of a river. Because they got there tens of millions of years before rodents, over ages they evolved to exploit all kinds of niches. There are mouse lemurs, squirrel-like lemurs, monkey-like lemurs; there were —> Read More
