Curiosity is common to human beings at all ages from infancy to old age, and is easy to observe in many other animal species. These include apes, cats, fish, reptiles, and insects; as well as many others. Many aspects of exploration are shared among all beings, as all known terrestrial beings share similar aspects: limited size and a need to seek out food sources.
Strong curiosity is the main motivation of many scientists. In fact, in its development as wonder or admiration, it is generally curiosity that makes a human being want to become an expert in a field of knowledge.
In a milder form, however, this can be understood as a cathartic form of behavior or as something instinctive within humans. According to Aristotle, in his Poetics we even "enjoy contemplating the most precise images of things whose sight is painful to us." (This aspect of our nature is often referred to as the 'Car Crash Syndrome' or 'Trainwreck Syndrome', derived from the notorious supposed inability of passersby to ignore such accidents.)
