4. Digestive System Adaptations
One amazing example of biological creativity is the way termites' digestive system has evolved.One of the most plentiful yet challenging compounds in nature, cellulose, has been broken down by specialist bacteria housed in the unusual stomach structure these insects have formed.Their digestive tract has developed several chambers designed as fermenting vessels, which enable effective digestion of wood fiber.They have also evolved specialized organs known as proctodeal trophallaxis, which help them to pass these essential gut symbionts to other colony members.Termites have a great evolutionary advantage since their complicated digestive adaption has let them take advantage of a food source few other creatures can use.
