Lineages of arthropods colonised land across the similar time as land crops, most likely between 510 and 471 million years in the past through the Late Cambrian or Early Ordovician. Vertebrates such because the lobe-finned fish Tiktaalik began to move on to land within the late Devonian, about 375 million years ago.
