jawless fishes
They were the original form of life and they came before vertebrates.
the did not evlove from that. they evloved from something else. once i find out i will put it out here.
Sharks are a type of fish. This is because fish are defined as being vertebrates with gills.
Arthropods have had more time to co-evolve with land plants than other vertebrates.
No. The 1st vertebrates appeared in the fossil record about 525 million years ago during the Cambrian Period. This was in the Paleozoic Era.
After fish, amphibians were the next group of creatures to evolve on Earth. Amphibians are cold-blooded vertebrates that can live both on land and in water. They were the first vertebrates to colonize terrestrial habitats.
The similarity in the number and location of bones between many fossil vertebrates and living vertebrates supports the concept of evolutionary relationships and common descent. This evidence indicates that vertebrates share a common ancestor, and the similarities in their skeletal structures can be attributed to evolutionary adaptation and divergence over time. Such patterns are foundational to the theory of evolution, illustrating how species evolve while retaining underlying anatomical traits.
Snakes are vertebrates.
vertebrates
A toucan is a bird, and all birds are vertebrates.
Birds are considered one of the most successful vertebrates due to their diversity, adaptability, and ability to inhabit nearly every ecosystem on Earth. Their unique adaptations such as flight, beaks, and diverse diets have allowed them to thrive and evolve into over 10,000 species globally.
