according to Allen rule extremities (limbs) of mammals are small in colder region and large in warmers , not the body size. as heat loss from extremities is very rapid. ex. penguins have short flaps

Thanks Rajat...
Respected Sir, Thanks a lot for such wonderful initiative. One feedback from myside - Keep the speed little bit slow and explain in more detail. Whatever words you write while teaching kindly also explain them little bit in detail. It become very difficult to understand concept. Rest is awesome.
