Both mammals and birds are descended from reptiles.

The five classes of vertebrates (fish, amphibians, reptiles, birds, mammals) evolved in the following order: fish appeared first, followed by amphibians, then reptiles, birds, and finally mammals. Each class adapted and diversified to exploit different environments and ecological niches over millions of years.
vertebrates(with a backbone) 1. breathe through lungs 2.live on land (most of them>>reptiles) 3.internal fertilization
the 5 groups of Vertebrates are: 1.Fish 2.Amphibians 3.Reptiles 4.Birds 5.Mammals
Vertebrates are animals that has a backbone. Here is a list of vertebrates.horseshumanszebrasdinosaurs (they are extinct)deerssheeplionstigerselephanthipposdogscats
According to their common traits.The main division is into the 2 categories: vertebrates (with backbone) and invertebrates (without backbone).Vertebrates can be sub-divided into 5 groups: Fish, Reptiles, Amphibians, Birds and Mammals.Livings things are classified into:DomainKingdomPhylumClassOrderFamilyGenusSpecies

Animals are divided into two main groups: vertebrates and invertebrates. Vertebrates are animals with a backbone or spinal column, such as mammals, birds, reptiles, amphibians, and fish. Invertebrates, on the other hand, are animals without a backbone, including insects, arachnids, mollusks, and annelids.
Animals with backbones, or spinal columns, are called vertebrates. There are only around 65,000 known species of vertebrates. This sounds like a lot, but it is only about 3% of all the animals on Earth. Most animal species are invertebrates, i.e., with no backbone.The 5 types of vertebrates are: mammals, birds, fish, amphibians, and reptiles.These animals are all part of the phylum chordata, meaning having a spinal cord.
