What is the difference between Chordate and Primate?

Chordates are a diverse group of animals that possess a notochord at some stage of their development, along with a dorsal nerve cord, pharyngeal slits, and a post-anal tail. This phylum includes various organisms such as fish, amphibians, reptiles, birds, and mammals. Primates, on the other hand, are a specific order within the class Mammalia, characterized by traits such as large brains, forward-facing eyes, and flexible limbs. Essentially, all primates are chordates, but not all chordates are primates.
