Animals that have two sets of teeth, one followed by the other, are said to be diphyodont. Normally the dental formula for milk teeth is the same as for adult teeth except that the molars are missing. Because mammal teeth are specialised for different functions, many mammal groups have lost teeth not needed in their adaptation. Tooth form has also undergone evolutionary modification as a result of natural selection for specialised
Eastern Highlands moist deciduous forests winds from the Bay of Bengal, which lies to the southeast. The ecoregion is bounded on the north and west by tropical dry deciduous forest ecoregions, including the Central Deccan Plateau dry deciduous forests to the southwest and west, the Narmada valley dry deciduous forests to the northwest, and the Chota Nagpur dry deciduous forests to the north and northeast. The drier Northern dry deciduous forests ecoregion, lying west of the Eastern Ghats range, is completely surrounded by the Eastern Highlands moist deciduous forests, in the rain shadow of the Ghats, which partially block the moisture-laden monsoon winds off the
