Principle 1: Genetic variations Genetic variations present itself in all animals including tawny owls. All tawny owls or brown owl with pale underparts with dark streaks, and the upper parts are either brown or grey.
Principle 2: overproduction and the struggle to survive Tawny owls have such a great adaptation that they are able to live long to produce offspring. The only problem being if they reproduce to rapidly the environment would lack the resources they need to survive.
Principle 3: Survival and Reproduction of the Fittest It is easier for the owls to catch their prey because their adaption allows them to not only find their prey but easily catch them by sneaking up on them.
Principle 3: Survival and Reproduction of the Fittest Since the tawny owls could catch their prey with ease it allows them to survive longer and reproduce.
Principle 4: Changes in gene pool Since the owls that have adapted to the environment in which they live with their hearing and eyesight plus their ability to sneakup on prey. In the future
