Bipedal Quotes (3 quotes)
As the human fetus develops, its changing form seems to retrace the whole of human evolution from the time we were cosmic dust to the time we were single-celled organisms in the primordial sea to the time we were four-legged, land-dwelling reptiles and beyond, to our current status as largebrained, bipedal mammals. Thus, humans seem to be the sum total of experience since the beginning of the cosmos.
From interview with James Reston, Jr., in Pamela Weintraub (ed.), The Omni Interviews (1984), 99. Previously published in magazine, Omni (May 1982).
In the early seventies my mother [Mary Leakey] returned to Laetoli, a site in Tanzania that my parents had discovered in the thirties. In 1976, she discovered footprints of ancient hominids. These three-and-a-half-million- year-old footprints provide evidence of bipedality.
In Pamela Weintraub, The Omni Interviews (1984), 60.
The human species was born when one isolated group of bipedal apes got itself stuck and then speciated to get better survival value out of eating meat.
In Pamela Weintraub, The Omni Interviews (1984), 66.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) --
