The leading theory on prehistoric giant insects is crumbling, and here's what scientists think now

Giant prehistoric insects, some with two-foot wingspans, once roamed Earth. For years, scientists believed higher oxygen levels fueled this gigantism. However, new research reveals insect breathing tubes were surprisingly small, challenging the oxygen-only explanation. This discovery opens doors to new theories, including reduced predation and exoskeleton limits, reshaping our understanding of ancient life.
