Excerpted from Beyond Words by Carl Safina, ©2015:
At Gombe Stream National Park in Tanzania, a researcher watched two adult male chimpanzees separately climb to the top of a ridge at sunset. There they noticed and greeted each other, clasped hands, sat down together, and watched the sun descend. Another researcher wrote of a free-living chimpanzee gazing for fifteen minutes at an especially striking sunset. If they really are admiring the sunset, it’s probably for no deeper reason than it looks pretty to them. Same as us. Perhaps they feel a sense of wonder, that raw material for the questions to which humans hammered the answer of religion.
