<P0-S0>  Most residents belong to the Channa Caste. <P0-S1> Channa Mohallah is a town in Jacobabad in Sindh, Pakistan. <P0-S2>  50% or more of the population are of Channa caste; it is the most popular area in Jacobabad for the caste. <P0-S3>  The main places also in Channa Mohallah are the power grid station and Shah Abdul Latif Bhitai Stadium Ground. <P0-S4>  Also nearby is Shahbaz Air Base. <P0-S5>  Now there is a big project under construction J.I.M.C.: the Jacobabad institute of Medical Sciences. <SEP> <P1-S0>  The most common stone tool recovered from the site is a chert oval biface and is associated with agriculture and thought to have been used for weeding and hoeing. <P1-S1>  There is also some evidence of stone tool production at the site. <P1-S2>  Research has shown that K’axob was occupied from the Late Preclassic Period to the Early Postclassic Period. <P1-S3>  K’axob is mostly based on residential and household living but also has some ritualistic aspects. <P1-S4>  There is also evidence of specialized areas for pottery production. <P1-S5>  K’axob is a village site centered on two pyramid plazas and later grew in size during the Early Classic Period to the Late Classic Period. <P1-S6>  The site includes a number of household, mounds and plazas. <P1-S7>  The site is located in northern Belize in the wetlands of Pulltrouser Swamp in proximity to the Sibun River Valley in central Belize. <P1-S8>  Many of the individuals, some more than others, were interned with beads made of shell as well as ceramic vessels, demonstrating this potential social stratification. <P1-S9>  Many of the structures at the site show evidence of household dwellings as well as ritual purposes. <P1-S10>  The pottery vessels recovered from the site demonstrates regularity in the production of pottery. <P1-S11>  There are many burials at the site that illustrate the ritualistic aspects and social stratification at K’axob. <P1-S12>  There are middens at the site that yielded a great deal of pottery sherds and are associated with structures that are believed to be kilns as well as with tools similar to modern pottery making tools. <P1-S13>  This period in time and the site is characterized by specific ceramic types as well as agriculture and an increase in social stratification. <P1-S14>  The most prominent type of ceramic vessels recovered from the site were ‘serving bowls,’ with a tripodal base, and were present during the Early Classic Period. <SEP> <P2-S0> A society is a group of people involved in persistent social interaction, or a large social group sharing the same geographical or social territory, typically subject to the same political authority and dominant cultural expectations. <P2-S1>  Societies are characterized by patterns of relationships (social relations) between individuals who share a distinctive culture and institutions; a given society may be described as the sum total of such relationships among its constituent of members. <P2-S2>  In the social sciences, a larger society often evinces stratification or dominance patterns in subgroups. <SEP> <P3-S0>  Although caste systems exist in various regions, its paradigmatic ethnographic example is the division of Indian society into rigid social groups, with roots in India's ancient history and persisting until today. <P3-S1> Caste is a form of social stratification characterized by endogamy, hereditary transmission of a lifestyle which often includes an occupation, status in a hierarchy, and customary social interaction and exclusion. <P3-S2>  However, the economic significance of the caste system in India has been declining as a result of urbanization and affirmative action programs. <P3-S3>  A subject of much scholarship by sociologists and anthropologists, the Indian caste system is sometimes used as an analogical basis for the study of caste-like social divisions existing outside India. <P3-S4>  The term is also applied to non-human populations like ants and bees.
