Chapter 25, Problem 10SQ
Summary Introduction
Concept introduction: The birds in order to avoid competition on land, they evolved the volant adaptation. To suit the volant adaptation, they developed wings that are made up of feathers, and this helps the birds to fly. The hair and fur of the mammals cover the epidermis and insulate the internal anatomy from the harsh and cold environment that is found outside. Both the hair and feather are made up of a protein known as keratin.
