How we evolve

Technology might some day enable us to control aspects of evolution, or it may prove to be the ultimate selection regime, culling all of us. Perhaps we already find ourselves wishing we’d lacked the intelligence to monkey with howitzers. Either way, the culture that we’ve created is, strangely, evolution’s most powerful tool and its potential nemesis, the womb of human nature and perhaps its grave. By our own hand: this is how we evolve.
