Darwinian evolution is adaptive and slow … millennia can go by before a species changes very much. But with the tools of genetic engineering we can now make radical changes in just one generation. By removing genes or inserting new ones, we can give an organism radically different traits and behaviors. We are taking evolution into our own hands.
It all began with the domestication of plants and animals, which one science writer says created civilization. Today, as humans tinker with their own genome, is it possible we will produce Homo sapiens 2.0?
