Living matter “hitches a ride on sunlight or inside rocks.” Some scientists believe that Mars was indeed inhabited at one time. The brain is dorsal to pharynx in the head in Chordates, while in Non-chordates it is absent or above pharynx (if present). All vertebrates are chordates, and almost all chordates are vertebrates apart from a few that aren't. Humans are not chordates because humans do not have a tail. Chordate, any member of the phylum Chordata, which includes the vertebrates, the most highly evolved animals, as well as two other subphyla—the tunicates and cephalochordates. Because of critters like this guy: That’s a lancelet. Can be absent or diploblastic or triploblastic. In some chordates, all four traits persist throughout life and serve important functions. The physical characteristics of Chordates are noticed on the presence of a post-anal tail, pharyngeal slits a notochord, an endostyle and a hollow dorsal nerve cord.
