1) семена попадают в неблагоприятные условия среды и не прорастают
Поедаются животными, грибами, бактериями
Конкурируют в благоприятных условиях с другими растениями за свет и воду и не вырастают.
2) У бабочек появилась мутация, обеспечивавшая им более темный цвет.(наследственная изменчивость). Такие бабочки были менее заметны на темных стволах деревьев, соответственно, меньше поедались птицами и размножались, а светлые бабочки погибали.
