Fig 1: Phylogenetic relationship between birds, snakes and lizards.

As shown in Fig 1: “Phylogenetic relationship between birds, snakes and lizards”, the birds as well as the snakes and lizards shares common ancestors. Due to presence of the common ancestry with the reptiles, the birds have scales on its feet.

Scales are the thick, dry and keratinized in nature. Snakes and lizards use their scales to provide contact with substrates such as trees and also create the movement. The feathers in the birds are the modified scales.
