I, too, am convinced that our ancestors came from Africa.
Interpretation
This quote emphasizes the shared ancestry of all humans, originating in Africa.
Richard Leakey's quote reflects the scientific consensus on human evolution, suggesting that all modern humans share a common ancestor that originated in Africa. It highlights the interconnectedness of humanity and evokes a sense of unity among diverse cultures and races, rooted in a shared biological heritage.
In practice
In a lecture about human evolution, I would quote Richard Leakey to underscore our shared origins.
For three million years we were hunter-gatherers, and it was through the evolutionary pressures of that way of life that a brain so adaptable and so creative eventually emerged. Today we stand with the brains of hunter-gatherers in our heads, looking out on a modern world made comfortable for some by the fruits of human inventiveness, and made miserable for others by the scandal of deprivation in the midst of plenty.
To have arrived on this earth as a product of a biological accident, only to depart through human arrogance, would be the ultimate irony.
Earlier, 100,000 elephants lived in Kenya and we didn't have any noteworthy problem with it. The problem that we have is not that there are now more elephants.
We are concerned that, in a few years time, this place of discovery, with its wealth of human fossils, the like of which can be found nowhere else in the world, could be completely destroyed.
I lose sleep at night wondering whether we are intelligent enough to figure out the universe. I don't know.
Mystics exult in mystery and want it to stay mysterious. Scientists exult in mystery for a different reason: It gives them something to do.
It was the late Dr. Mahendra Lal Sircar who, by founding the Indian Association for the Cultivation of Science, made it possible for the scientific aspirations of my early years to continue burning brightly.
Science is basically an inoculation against charlatans.
The calculus was the first achievement of modern mathematics and it is difficult to overestimate its importance. I think it defines more unequivocally than anything else the inception of modern mathematics; and the system of mathematical analysis, which is its logical development, still constitutes the greatest technical advance in exact thinking.
The great tragedy of science - the slaying of a beautiful hypothesis by an ugly fact.
