Amniote clade

The Amniote clade is a group of vertebrate animals that includes reptiles, birds, and mammals. They are characterized by having an amniotic egg, which allows them to reproduce on land without needing water for their eggs. This adaptation provides a protective environment for the developing embryo, enabling amniotes to live in diverse habitats. They also share other features like certain skull structures and body cavity arrangements. Essentially, amniotes are a major evolutionary branch that has successfully colonized terrestrial environments, leading to the diverse array of land and flying animals we see today.
