More than 62,000 vertebrate species have been identified. The vertebrate species now living represent only a small portion of the vertebrates that have existed. The best-known extinct vertebrates are the dinosaurs, a unique group of reptiles, which reached sizes not seen before or after in terrestrial animals.

They acknowledged incomplete genome sequencing with many gaps and extensive repetitive DNA.

It introduces the recapitulation theory, which posits that early developmental stages mirror ancestral forms, despite variations among species. The page notes that while embryos exhibit analogous features like limb bud formation, many are lost or altered later.

Freshwater vertebrates excrete excess water for homeostasis, while amphibians adjust filtration for water conservation. Reptiles and birds convert nitrogen wastes to uric acid for reduced water loss, whereas mammals primarily excrete urea with varied efficiency.
