Becoming Human



READER QUESTION:   We now know from evolutionary science that humanity has existed in some form or another for around 2 million years or more. Homo sapiens are comparatively new on the block. There were also many other human species, some which we interbred with. The question is then inevitable – when can we claim personhood in the long story of evolution? Are Chimpanzees people? Did Australopithecine have an afterlife? What are the implications for how we think about rights and religion? Anthony A. MacIsaac, 26, Paris, France.

In our mythologies, there’s often a singular moment when we became “human”. Eve plucked the fruit of the tree of knowledge and gained awareness of good and evil. Prometheus created men from clay and gave them fire. But in the modern origin story, evolution, there’s no defining moment of creation. Instead, humans emerged gradually, generation by generation, from earlier species.

As with any other complex adaptation – a bird’s wing, a whale’s fluke, our own fingers – our humanity evolved step by step, over millions of years. Mutations appeared in our DNA, spread through the population, and our ancestors slowly became something more like us and, finally, we appeared.  TO READ MORE, CLICK HERE...
