In ancient times, oceans and lakes teemed with dominant creatures like the anomalocarid and kunmingia, leaving weaker organisms confined to harsh shallow waters. Later, when even these habitats became overcrowded, they were forced to venture onto land, seeking survival in places devoid of water. However, most of these land-going creatures eventually went extinct. Only a few fortunate species survived by chance--the earliest land plants, appearing during the Ordovician period approximately 450 million years ago. Soon after, insects followed suit. From that point onward, insects and plants co-evolved, giving rise to the astonishing array of shapes and behaviors we observe in these species today.
