All mammals undergo a certain degree of diversification. Darwin knew that. When he drew a family tree, it had many branches on it.
In our case, finding a Lucy is unique. No one will ever find another Lucy. You can't order one from a biological supply house. It's a unique discovery, a unique specimen.
I was aware of it, but I grew up in a very a-religious family. My mother never went to church, she never had any religious training or background. It was never a part of our social interaction.
Journalists often ask me when I go to the field, 'What do you expect to find?' And my answer always is, 'The unexpected,' because we're just looking at the tip of the iceberg; we've just scratched the surface.
And what I wanted to do was, I wanted to explore problems and areas where we didn't have answers. In fact, where we didn't even know the right questions to ask.
I was being groomed as an undergraduate to specialize in Midwestern prehistory, but going back to my teenage days, my interest has always been in our early human ancestors. I wanted to work in Africa.
