Final answer:
Innate behaviors are natural, instinctive behaviors that occur in all members of a species. While the behavior itself is innate, there may be variations in how it is expressed among individuals.
Step-by-step explanation:
An innate behavior is any behavior that occurs naturally in all animals of a given species. Innate behaviors, also known as instincts, are closely controlled by genes and are largely independent of environmental influences. They do not have to be learned or practiced and are predictable across all members of a species.
Organisms within a species may show different variations of the same innate behavior, which is known as behavioral plasticity. This means that while the behavior itself is innate, there may be slight differences in how it is expressed or executed among individuals.
For example, in a bird species, the innate behavior of building a nest can vary in the specific materials used or the location of the nest, but the overarching behavior of nest-building is innate to all members of the species.
