A concept in evolutionary biology where natural selection acts at the group level rather than solely on individuals.

自し然ぜん選せん択たく
自然選択 (natural selection) is the broader mechanism; 群選択 specifically refers to selection at the group level.

個体選択 (individual selection) is the more standard Darwinian view, contrasting with 群選択.

Compound of 群 (group) and 選択 (selection), likely a calque from English 'group selection'.
