Human Family Tree Now a Tangled, Messy Bush

For anthropology students 30 years ago, learning human evolution was a breeze.

...

But in the late 1970s, we entered a golden age of human fossil discoveries that has repeatedly punched holes in the naive idea that our evolution would be that clear, clean, and straight.

Like most animals, humans have a checkered past, and our family album is now full of side branches and dead ends. And it's populated with creatures, such as the little people (Homo floresiensis) of Flores Island in Indonesia, that we could never have imagined in our wildest dreams.

The straight line has blossomed into a spreading, rather uncontrolled bush and we don’t like it. We want our history to be nice and neat, but the fossils keep messing us up.

...

The big news, then, is that these very different fossils are being hung on the human family tree on separate branches but at the same height. And once again, we have to reconsider the path of human evolution.

But should we be all that surprised?

This is a great human evolution story and we’ll know more once the original research team gets back to the caves in Flores and to the other islands. Hard to believe, but their work was halted by the Indonesian government at one point. Of course, I have a vested interest in hoping this story has some validity to it, having written a fictional novel called Flores Girl on the find. There is more on this ongoing controversy about Homo floresiensis at www.floresgirl.com.
