"Richard [Leakey] ran an expedition and as joint leader and main operator of the
practical side he felt that he had a right to loyalty from the expedition
members. Inevitably that meant agreement with him on all important factors
associated with the expedition..if you did not agree on important issues you
could either back down or leave. Most of us backed down a few times and then
eventually left…Despite this, my own preference would be to work for an
expedition run by Richard."
Donald Johanson, "acknowledges that the search
is often spiced by hopes that are not always strictly scientific. 'We have a
passion to find the oldest, the most complete, the biggest-brained, the most
enigmatic fossil,' he recently told an audience at a public lecture at the
American Museum of Natural History in New York. Many anthropologists feel
like this, but few are candid enough to express it publicly."
