kind of zoopharmacognosy use differs from one species to another. For example, Mountain Gorillas from Rwanda tend to ingest clay soil during dry season, when the vegetation changes forcing them to feed on plants that have more toxic compounds, in this case the ingested clay absorbs these toxins providing digestive benefits. This kind of seasonal behavioural adaptation is also seen in the Red-Handed Howler monkeys from the western Brazilian Amazonia, which also have to adapt to the shift of feeding on leaves that contains more toxic compounds. In other cases, geophagy is used by the Ring-Tailed Lemurs as a preventive and therapeutic behaviour for parasites control and intestinal infection. These benefits from clay ingestion can also be observed among Rhesus Macaques. In a study that was carried out in the Island of Cayo Santiago, it has been observed that the Rhesus Macaques had intestinal parasites and they were their health was not affected and they didn't have many gastrointestinal effects from these parasites. Data observed, shows that this was caused by the consumption of clay soil by this specie. On the other hand observations have shown that behavioural geophagy provides minerals supplements, as seen among Cambodian's Colobinae. The study was done at the salt licks in Veun Sai-Siem Pang Conservation Area, a site that is visited by various species of nonhuman primates. More in-depth research needs to be carried out in order to better understand this behavioural adaptation of geaophagy among nonhuman primates. Bats There is debate over whether geophagia in bats is primarily for nutritional supplementation or detoxification. It is known that some species of bats regularly visit mineral or salt licks to increase mineral consumption. However, Voigt etal. demonstrated that both mineral-deficient and healthy bats visit salt licks at the same rate. Therefore, mineral supplementation is unlikely to be the primary reason for geophagia in bats. Additionally, bat presence at salt licks increases during periods of high energy demand. Voigt etal. concluded that the primary purpose for bat presence at salt licks is for detoxification purposes, compensating for the increased consumption of toxic fruit and seeds. Humans Anthropological and historical evidence Evidence for the likely origin of geophagy was found in the remains of early humans in Africa: Geophagia is nearly universal around the world in tribal and traditional rural societies (although apparently it has not been documented in Japan or Korea). In the ancient world, several writers
