The same way humans do. By different types of mutations.
NEUROCRINE CARCINOMA is an old and somewhat ambiguous entity of malignant tumor. In general, NC is a tumor that demonstrates neurocrine differention. That can be a usual carcinoma with prominent neurocrine differention, a large cell neurocrine carcinoma, small cell carcinoma or an atypical carcinoid tumor(in the lung).

You are not being specific enough. There are many different adaptations for different 'air' animals
Some animals develop violent adaptations to their environment. These adaptations are common among predators and cause them to be aggressive towards other animals.
to hunt animals
do plants and animals adapt
animals go through adaptations to survive in the habitat
Tsunamis do not create adaptations in plants or animals.
all animals have to have adaptations in order to live. if an animal is living then it will always have adaptations
The Adaptions of Animals.
Claws.
The animal changes to they adaptations, but the adaptations might change because of the animals dieing off so much.
Bird migration and the hibernation of some animals during the cold seasons are behavioral adaptations. The physiological adaptations relate to the general functioning of the body.
