ou and I may never have evolved if it weren’t for relaxed selection. Humans have created a unique global niche where we are largely shielded from selective forces: Agriculture staves off starvation, medicine protects us from disease, cultural norms promote group harmony. Our evolution has been profoundly influenced by our selection-buffering behaviors. For instance, the appearance of some modern human features appears to be correlated with a rise in energy consumption,
