27. How did smaller dogs like bull terriers most likely evolve from wolves? A small bull terrier-sized puppy was born to a wolf The smallest wolf puppies were bred together over many generations Wolves were fed less and did not grow as large Wolf puppies were kept in the puppy stage so they did not grow large

Each beak shape helps the birds to produce different songs Each beak shape is an adaptation to a specific source of food Each beak shape is designed to construct a different type of nest Each beak shape helps protect the birds from a different predator

Predators on the main island can easily migrate to follow the populations to the other islands Lack of disease on the other islands enables the populations to grow and change without limit The climatic conditions of the islands allow the populations to breed all year and produce several generations The physical separation of the islands limits gene flow and interbreeding between the populations
