What was the last vertebrate on earth?

Answer 1

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.
