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.
Let us understand what our own selfish genes are up to because we may then at least have the chance to upset their designs.
My Design in this Book is not to explain the Properties of Light by Hypotheses, but to propose and prove them by Reason and Experiments: In order to which, I shall premise the following Definitions and Axioms.
It is hard to think of practical applications of the black hole. Because practical applications are so remote, many people assume we should not be interested. But this quest to understand the world is what defines us as human beings.
We explore because we are curious, not because we wish to develop grand views of reality or better widgets.
Without any doubt, the regularity which astronomy shows us in the movements of the comets takes place in all phenomena. The trajectory of a simple molecule of air or vapour is regulated in a manner as certain as that of the planetary orbits; the only difference between them is that which is contributed by our ignorance. Probability is relative in part to this ignorance, and in part to our knowledge.
It is a profound and necessary truth that the deep things in science are not found because they are useful; they are found because it was possible to find them.
