Since, for example, the tarsiers' eyes and ankle bones differ so much from those of other primates, the genes associated with eye . communicates by producing scents from special gland(s) and placing them on a surface whether others can smell or taste them, breeding is confined to a particular season, reproduction that includes combining the genetic contribution of two individuals, a male and a female. However, even in these situations, they will usually only resort to biting as a last resort.
