The way they lived - their surroundings. e.g., reptiles that needed to fly to catch their prey needed wings and so slowly evolution created what we know as birds and then the birs evolved to different varietys of birds depending on how they live e.g the whole needed binocular vision to cath its prey and so that's why owls have the shape of the head and eyes that they have.
A lot of animals are affected by aerosol sprays, most notably birds. Birds are very susceptible to airborne chemicals even Teflon use, incense and home deodorizers. Pollutants from spray can also wind up in an aquarium killing the inhabitants.
Discovered the Taung Child. One of the most important discoveries EVER! (in regards to evolution)
most birds of prey, such as Hawks, Owls and red kites...
The great Charles Darwin is most credited with the theory of evolution, but there were many before him that had similar ideas, and many people since have advanced the science of evolution.
Most birds -- and all birds that fly -- have semi-hollow bones. Most reptiles, however, do not.
Birds are not considered mammals because they do not feed their young milk and because they have feathers instead of fur. Birds lay eggs while most mammals give live birth. Birds are also distinguished by having beaks and a rather intricate and unique respiratory system. In terms of evolution, birds are more closely related to modern reptiles than they are to mammals.
In terms of evolution, hawks are most closely related to alligators. This is because birds evolved from dinosaurs and both alligators and dinosaurs are archosaurs.
i think pregnant woman is affected the most
Japan is a country that is most affected by them
Ducks are birds, and actually they can fly quite well. However, I believe your question is why can ducks swim when most other birds can't. The reason for this is evolution - ducks and other waterfowl like swans and loons have evolved into a niche that involves them eating directly from the water. Part of this evolution involved developing oil glands or preen glands on the base of their tails; waterfowl like ducks preen themselves constantly to spread this oil on their feathers to keep themselves waterproof so they can float on the water. Most non-waterfowl birds fly because they have evolved into a niche that involves them eating or hunting on the wing. However, I will note that not all birds can fly - penguins, ostriches, emus, rheas and kiwis all can't fly, but they are birds.
Flightless
Helium burning is most durable stage in stellar evolution.

Most mutations that occur have a neutral effect, or none at all, so they would not affect evolution. Organisms with mutations that cause detrimental impact typically will not survive; therefore, they will not reproduce, and the mutation will not be passed on, so the species will not be affected overall. Beneficial mutations are typically the only mutations that will affect an organism's posterity and the evolution of its species, but good mutations are very rare. This is why most mutations have little effect on the evolution of a species.
Scout, Jem, and Dill are most affected by their interactions with Boo Radley. Their perceptions of Boo evolve from fear and fascination to empathy and understanding as they uncover his humanity and glimpse the complexity of human nature. These experiences challenge their preconceptions and offer lessons in compassion and empathy.
