Integrity Quote of the Day

Donald Johanson

Discoverer of Lucy

I suggested in the first paper I published that there were at least two different kinds of hominids at this site. And I very soon thereafter began an extensive period of research with my colleague Tim White. And I remember the nights of argument in the laboratory in Cleveland, when we would literally be screaming at each other. Because he said: "There is only one species here. The big ones are males, the little ones are females. And if you lay them all out on the table, you have a gradual change from small, to larger, to larger, to largest. And there's no significant anatomical difference between the individuals in this collection. It represents only a single species, and the sooner you recognize that, the better off you are going to be." He was very forceful in his arguments. And I would go home and think about it, and go back the next morning and take out the jaws and see if I could establish a series of features that would vindicate me, and substantiate my view that there were two species. And, slowly this idea was eroded away, and I had to admit that what I had published was wrong. It was incorrect. I had made a mistake.
