E.3a Innate Behavior

If humans can identify each other and gorillas could identify each other, then would humans be to gorillas as gorillas are to humans? Discuss.
Words first, words words words. Innate behaviour is behaviour shown in all normal members of a species despite any variation in the environment. By contrast, learned behaviour is an alteration or modification of behaviour that is the result of experience.
DBQ page 326:
1. Another method to encourage the woodlice to move into one of the arms is to place food in one of the arms, which is a form of chemotaxis.
2. The data shows that most of the woodlice are attracted to the scented arm than to the unscented arm. Only a little over 30% moved into the unscented arm.
3. For the woodlice to receive smell and respond to it, they must have chemoreceptors that can react to the chemicals released by the smells.
- a) Woodlice would move to the scented arm because they know there are members of their own species there, and for survival and reproduction, that would mean that there are potential mates in that arm compared to the unscented arm. This means that woodlice might use scent for mating (to signal to each other their locations).
- b) Woodlice might move to the unscented arm to avoid competition and to survive by itself without reproduction. If large populations of the species tend to overpopulate, some woodlice may have learned to avoid their own species for a better chance of survival.
