* Crocodiles and alligators: Birds and crocodilians share a common ancestor that lived around 250 million years ago. This ancestor was likely a small, lizard-like creature that lived in trees. Over time, birds and crocodilians evolved into different groups, but they still share many similarities, such as their cold-bloodedness, their scaly skin, and their ability to lay eggs.

* Turtles: Turtles and birds are also closely related, and they share a common ancestor that lived around 320 million years ago. This ancestor was likely a small, semi-aquatic creature that lived in swamps and marshes. Over time, turtles and birds evolved into different groups, but they still share many similarities, such as their hard shells, their ability to lay eggs, and their cold-bloodedness.

* Snakes and lizards: Snakes and lizards are more distantly related to birds than crocodiles, alligators, and turtles, but they still share a common ancestor that lived around 340 million years ago. This ancestor was likely a small, lizard-like creature that lived on land. Over time, snakes and lizards evolved into different groups, but they still share many similarities, such as their cold-bloodedness, their scaly skin, and their ability to lay eggs.

* Mammals: Mammals are the most distantly related animals to birds, but they still share a common ancestor that lived around 370 million years ago. This ancestor was likely a small, furry creature that lived on land. Over time, mammals and birds evolved into different groups, but they still share many similarities, such as their ability to regulate their body temperature, their need for oxygen, and their ability to reproduce sexually.
