What is a characteristic of both an emperor penguin and galapagos penguin that evolved differently due to their different environments

Body size: The Emperor Penguin has larger body size compared to that of the Galapagos Penguin as a structural adaptive feature for heat regulation in their different environment.

Explanation:

The emperor penguin and the Galapagos Penguin, both live in different contrasting environments. Emperor penguins are found in cold habitats while the Galapagos Penguins are found in warm habitats. Both have evolved differently by developing several unique characteristics to make them adapt well to their different environment. Regulation of heat is one of the challenges they have to deal with to survive in their habitat. In doing this, both have evolved differently in the following ways:

The Emperor penguin: The large size of the emperor penguin’s which makes them have low smaller surface area in relation to volume. This helps it to retain heat and survive extreme cold temperatures in its environment.

The Galapagos Penguin: It has a small body size with a larger surface area in relation to its volume, which enables it to lose body heat more efficiently than the Emperor Penguin.
