Detailed explanation-1: -Therefore, the phrase “expressed in most individuals” is not correct in innate behavior. It is expressed in all individuals in a population.
Detailed explanation-2: -Innate behaviors are instinctive. They are controlled by genes and always occur in the same way. Innate behaviors do not have to be learned or practiced. Innate behaviors generally involve basic life functions, so it’s important that they be performed correctly.
Detailed explanation-3: -Reflexes. Perhaps the simplest example of an innate behavior is a reflex action: an involuntary and rapid response to a stimulus, or cue. One example of a human reflex action is the knee-jerk reflex.
Detailed explanation-4: -Evolutionary (ultimate) explanations Darwin’s theory of evolution by natural selection is the only scientific explanation for why an animal’s behavior is usually well adapted for survival and reproduction in its environment.
Detailed explanation-5: -Heritable-encoded in DNA and passed from generation to generation. Intrinsic-present in animals raised in isolation from others. Stereotypic-performed in the same way each time by each individual. Inflexible-not modified by development or experience. More items
