Доклад не смогу сейчас найти, но могу сказать: размер насекомых зависит от содержания кислорода в атмосфере. Доставка кислорода к органам насекомого осуществляется в системе ветвящихся трубочек – трахей, соединенных с отверстиями (дыхальцами) на поверхности тела. По мере роста насекомого объем его трахей увеличивается на 20% быстрее, чем масса тела.
Эта особенность дыхательной системы делает невозможным увеличение размеров тела выше определённого предела.
В конце палеозойской эры насекомые были намного крупнее, чем сейчас, что объясняется повышенной концентрацией кислорода в атмосфере
