The phylum Chordata is most closely related phylogenetically to the first vertebrates. Chordates share a number of characteristics with vertebrates, such as having a notochord, dorsal nerve cord, and pharyngeal slits. Cells within the notochord further develop into the vertebrae that define vertebrates.
jawless fishes
Life is believed to have first emerged in the ocean, with simple single-celled organisms appearing around 3.5 billion years ago. The transition to land began with plants, specifically mosses and liverworts, around 470 million years ago, followed by arthropods like insects and crustaceans. Vertebrates, such as amphibians, were among the first animals to make the leap to land approximately 360 million years ago. This progression marked the gradual colonization of terrestrial environments by various life forms.
No, the first vertebrates evolved long before the Mesozoic. The first vertebrates, small jawless fish, evolved around 520 million years ago. Land animals had even evolved long before the Mesozoic Era.
