One would be a giraffe's long neck; their long necks enable them to reach the leaves at the top of the trees they feed on. Their tongues are also rough because some plants they eat have sharp thorns

Because it is an excellent survival mechanism.

Natural selection- which is the mechanism driving evolution
Many animals (specifically mammals) do have all of the above. It is a survival mechanism thought to have helped the survival of the species.
no it does not. it is a survival mechanism, you can drink your pee twice before it is toxic if you are dying of thirst.
Evolution is the result of a process called survival of the fittest. Genes are part of the mechanism by which this happens.
Neutral buoyancy is the ability to float under water. This allows the animal to save energy.
This is another statement that describes "survival of the fittest."
Sand dollars have a survival mechanism where they burrow into the sand to avoid predators and turbulent wave action. They can also regulate the amount of water inside their bodies to control buoyancy and help them stay afloat above the sandy bottom. Additionally, their hard exoskeleton provides protection from predators and helps with camouflaging against the sand.
Dogs always have and always will bite. It is a defence mechanism and a way of hunting food for survival. Most animals bite. Humans included.
Charles Darwin called his mechanism of change "natural selection." This process favors the survival and reproduction of organisms that are best adapted to their environment, leading to the gradual change of species over time.
