First insect on earth
Summary. Insects are important because of their diversity, ecological role, and influence on agriculture, human health, and natural resources. This chapter documents the dominance of insects in the living world and shows how they have been central to many advances in science. Insects create the biological foundation for all terrestrial ecosystems.We dated the origin of insects to the Early Ordovician [~479 million years ago (Ma)], of insect flight to the Early Devonian (~406 Ma), of major extant lineages ...
