Silk is obtained from pupal nests or cocoons spun by larvae known as silkworm.. Despite some aspects in their surroundings, insects show a great way of adaptation to environmental conditions and maintain their internal temperature and water content within tolerable limits. Unfortunately, silkworms are very delicate and unable to survive in extreme temperature and humidity. So silkworms were and are domesticated at the north of China where great geographic settings are such as plateaus and deserts with a warm temperature.
\Natural geographic resources and shared knowledge resulted in the development of such advancements as silk.
Wearing silk was an important status symbol., partially used in noble class.
