vertebrates evolved from micro-organisms many millions of years ago...
Another point of view:
This actually depends upon your personal view. For the Christian, the story of creation as it appears in the book of Genesis clearly indicates that the first vertebrates appeared on the fifth day of creation, when God created birds, fish and other sea creatures.
Oldest known vertebrateA five-centimetre fossil, known as the Ediacara Chordate and uncovered in South Australia is believed to be the oldest vertebrate ever found. The fossil looks like an elongated tadpole and is believed to be at least 560 million years old.The first vertebrates appeared around 500 million years ago during the Cambrian period. These early vertebrates were jawless fish-like organisms that evolved into more complex forms over time.
The vertebrate jaw first appeared in early jawless fishes, such as the now-extinct Placodermi, around 450 million years ago during the Ordovician period. This evolutionary development allowed for more efficient feeding and contributed to the success of jawed vertebrates.
Anatomically modern humans first appear in the fossil record in Africa about 195,000 years ago.
Homo sapiens first appeared in Africa around 300,000 years ago during the Middle Pleistocene.
The first key hominid trait to appear in the fossil record is bipedalism, which refers to the ability to walk upright on two feet. This adaptation is characteristic of early hominids and distinguishes them from their primate ancestors.
The first group of hominids is believed to have first appeared in Africa, around 6-7 million years ago. This is supported by fossil and genetic evidence.

Jawless fish - the earliest known vertebrate was the Myllokunmingia.
The first vertebrate was Pikaia, which lived 510 million years ago, 280 million years BEFORE dinosaurs.

Amongst the living the most primitive vertebrate is the Hagfish.

Vertebrates are basically animals with backbones. The "last vertebrate on Earth" doesn't make sense unless you are reading a story about the end of the world or possibly a creation myth. There are currently a vast number of vertebrate species and identifying the last one to appear would be virtually impossible.From a scientific perspective, it makes much more sense to ask when did the first vertebrates appear on Earth, or which vertebrates have appeared most recently. Within the fossil record, there would be an oldest fossil of a vertebrate that would be a good candidate for he first vertebrate. Alternatively, you might choose a larger group of organisms like mammals and ask which was the last class of organisms to appear in the fossil record. In this case, the class of vertebrate whose oldest known fossil is the youngest or most recent could be called the last vertebrates on Earth.On the other hand, if you are somehow taking a class or thinking in a way that combines science and religion in a nonscientific way, it might be possible to answer the question based on the Christian creation story by saying "humans" or even "Eve." In this case, the question would be better phrased as "When God created the world, which was His last creation that would today be called a vertebrate?" In this case, the question is almost a riddle.
