minus-squaret_beriumlinkfedilinkEnglisharrow-up23·3 个月前Not sure, but I think that wasn’t because of higher temperatures but higher levels of oxygen in the atmosphere.
minus-squareMachinistlinkfedilinkEnglisharrow-up7·3 个月前Correct! Insects have spiracles that basically passively exchange air. Max size is basically determined by this. IIRC, some caterpillars only stop growing and pupate when they run out of a growth hormone. I always wondered what would happen if you grew them in a high oxygen tank and supplemented their diet with the hormone. Maybe get a Mothman that way.
