Donald Johanson quotes about
You don't just magically flip some evolutionary switch somewhere and transmute a quadruped into an upright-walking bipedal human.
branches certain darwin drew family knew mammals undergo
All mammals undergo a certain degree of diversification. Darwin knew that. When he drew a family tree, it had many branches on it.
change committed hard particular
It's very hard for all of us, when we've committed ourselves to a particular interpretation, to change our minds.
detailed fossil human lab opportunity realized species until
But it really wasn't until three to four years later, when we had an opportunity in the lab to make very detailed observations, and comparisons with other fossil discoveries, that we realized she was a new species of human ancestor.
elephants filled giraffes huge literally monkeys museum national room tons
If you were to go to the National Museum in Addis Ababa, you would walk into a huge room filled with literally tens of tons of fossils, and most of them would be elephants and rhinos and hippopotamus and monkeys and giraffes and antelopes and so on. Hominids are very rare in the landscape, and it's very rare to find them.
certainly human produce species time
Where we are going as a species is a big question. Human evolution certainly hasn't stopped. Every time individuals produce a new zygote, there's a reshuffling and recombination of genes. And we don't know where all of that is going to take us.

age ancestors changed considered evidence far goes gone good million modern six time twice upright walking wrote
What's changed is we now have good anatomical, geological, archaeological evidence that Neanderthals are not our ancestors. When I wrote 'Lucy,' I considered Neanderthals ancestors of modern humans. We have gone back twice the age of Lucy, six million years. And we see that upright bipedal walking goes back that far in time.
latin man men placed supposedly whether
We are placed in the genus of Homo, which is Latin for man - Homo sapiens: supposedly wise men. I sometimes think - wonder - whether we really are wise men.
regardless
Regardless of what we look like on the outside, genetically, on the inside, everyone is an African.
