Vertebrates
Vertebrates are animals that belong to the subphylum Vertebrata, characterized by the presence of a backbone or spinal column, which provides support and protection for the body. This group includes a wide range of species, from Fish to Mammals, Birds, and Reptiles. The vertebrate body plan is highly versatile, with adaptations that enable these animals to thrive in various environments, from the deepest oceans to the highest mountains. The study of vertebrates is closely tied to the field of Physiology, which seeks to understand the functions and processes that occur within living organisms. Vertebrates have evolved complex systems, including the Cell nucleus and Base pair mechanisms, which are essential for their survival and reproduction.
