A drafter, draftsperson, or draughtsman is a person who makes a drawing (technical or expressive). A professional drafter who makes technical drawings is sometimes called a drafting technician. Professional drafting is a desirable and necessary function in the design and manufacture of complex mechanical components and machines.
Introduction. Behavior is determined by a combination of inherited traits, experience, and the environment. Some behavior, called innate, comes from your genes, but other behavior is learned, either from interacting with the world or by being taught. Let's read about some pet behavior and try to figure out if it's learned or innate.
An instinct is a behavior that is acted out, not done by free will or choice. Animals react to things without thinking about it and the reaction they had was completely functional the first time they performed it. Animal instinct may be hereditarily based. This means that traits are passed on from generation to generation. As time goes on, traits that are more likely to help the species survive remain, and traits that do not may eventually disappear. This is in direct relation to the preservation of the animal. This is also related to natural selection.
