Lack of Hand Preference in Wild Hanuman Langurs

The lack of manual palatability by the wild Presbytis Entellus is a habitual study to investigate various challenges in the Hanuman / Langur nature group. Artificial specialization is the best indicator of powerful hemisphere localization well known to human scientists and is clearly demonstrated by Homo sapiens showing right-handedness of 90%. Researchers wanted to test if Hanuman Langur showed his preference on one hand. They assume that Hanuman Rangoul likes his right hand when completing his daily work.

Hanuman langur - A detailed study on the population of Hanuman langur in dry, deciduous and semi-green habitat. Because of the lack of systematic and long-term research on tropical rain forest Hanuman langurs, this research will be conducted in the Western Ghats rainforest in Gerusoppa, Uttara, Cantada. A single group (total of 17), including 8 females, 5 teenagers / 5 sub-members, and 3 babies was selected. The survey area is an evergreen tropical rain forest along the low altitude coast of the West Ghats mountain range of Utara and Kanada (Gerusoppa). Forests are mainly Dipterocarpus-Holigarna-Persia, average altitude 650 m, average annual rainfall 4200 mm, and relatively humid 95%.

The primate killing was first observed in Semnopithecus entellus and has been explained by five different hypotheses. Colobin snub nose Lang (Rhinopithecus spp.) Is closely related to Hanuman Langour. In addition to female seasonal breeding - perinatal period, it is accepted throughout the year. Rhinopithecus species often form a large group of multiple single male units (OMU), but men can only mate with his OMU. Even if male acquisitions occur, most women will remain at OMU, but a few women can be transferred to another woman. Male boys were expelled from the OMU to the entire male of the organization. Establishment of OMU to acquire infertility women is the ultimate goal of the bachelor's degree. OMU grouping mode helps kill infants at the time of male acquisition. Therefore, infant pesticides are expected to be relatively common in simple languages. Here we show the observation results of two Langur species (Rhinopithecus spp.).
