My recent trip to Africa was one of the great trips of my life. Seeing animals in their natural habitat is a concept that sticks in your brain for a long time. There are animals who have evolved there over many millions of years, adapted to their environments, are not bound by cages or bars, and have learned to live with each other. It's possible to see how humankind evolved from this setting, but it's almost impossible to imagine the scale of time required to do so. The trip was full of amazing surprises, one after another.
