Ancestral wild wheat varieties have a trait where seed heads shatter when ripe, allowing easier seed dispersal. When humans domesticated wheat, they selected for a mutation that reduced shattering so that harvesting the wheat seeds was easier. Use Darwin’s 3 principles of natural selection to compare how this trait evolved in wild wheat and was artificially selected for in domestic wheat.
