Detailed explanation-1: -Now buzzing and whizzing around every continent, insects were mysteriously scarce in the fossil record until 325 million years ago – when they first took flight and, according to a new study, evolutionarily took off.
Detailed explanation-2: -Insects were the first to evolve flight, approximately 350 million years ago.
Detailed explanation-3: -Insect ancestors (Hexapoda) likely originated during the Early Ordovician Period, about 479 million years ago. Insect flight emerged around 406 million years ago, around the same time plants began to really diversify on land and grow upward into forests.
Detailed explanation-4: -Insects were the first creatures to evolve flight, developing wings around 400 million years ago – 175 million years before the pterosaurs, the next animals to take to the skies.
