Avoiding Predation
Most animals get their food from preying on other organisms, and much of the life of animals involves eating and avoiding being eaten.
So it is not surprising to find many examples of adaptations that ...

predation
An interaction between species in which one species, the predator, eats the other, the prey.

predation One of the biological interactions that can limit population growth; occurs when organisms kill and consume other living organisms.
Predation when a larger animal eats other (smaller) animals
(preda = prey‚ booty)
Presbyopia being farsighted‚ not being able to see close objects clearly

Predation. The consumption of one organism by another
Predator. An organism that consumes another living organism (carnivores and herbivores are both predators by this definition) ...
predation The derivation of an organism of elements essential for its existence from organisms of other species that it consumes and destroys. The ingestion of prey by a predator for energy and nutrients.
To test the bird predation hypothesis, he released moths of each type (light and dark). In the unpolluted area, he recaptured 13.7% light, 4.7% dark indicating that the light form survived better. In the polluted area, he recaptured 13% light and 27.
In the above cases, mutations appeared which gave resistance to predation. Mutations which confer resistance to parasites have also been seen in studies of bacteria growing in chemostats.
Symbiosis has come to include all species interactions besides predation and competition. Mutualism is a symbiosis where both parties benefit, for example algae (zooxanthellae) inside reef-building coral.
These barnacles and mussels, without predation by the starfish, would come to dominate the community. In a classic 1966 study, Robert Paine removed starfish from enclosures.
Coloration that allows an organism to match its background and hence become less vulnerable to predation or recognition by prey.

Mullerian mimicry - mimicry that exists between two or more inedible or poisonous species; thought to result from convergent evolution and a mechanism reducing loss to predation by simplification of the recognition process; ...

On the other hand, the reduction of predation or an increase in the food supply (e.g., Darwin's finches) allows atypical genotypes to compete on more nearly equal terms with their formerly better adapted relatives.
