They think it might be genetic because some of our ancestors might have not gotten enough to eat, which lead to their death. This causes hanger to become a natural response to low glucose levels.

1. so they can survive when the winter comes 2.by sweetining there cells with glucose and increasing there urea there able to survive these cold weathers 3.he wants it to use it on human organs to let them adapt to cold tempatures like that

So they can be ready for the winter.The glucose and the urea act as cryoprotectants substances that lower the freezing temperature of the animal's tissues. He wants to use it to help human organs to adapt to transplant.

1.so that when the winter comes there able to go out 2.by swetning there cells with glucose and increasing there urea there able to survive the cold tempatures 3.so that humans can adapt to the frezing cold and be able to stay out there

1.So they can be ready for the actual freezing cold.In August it is not as cold so it is like practicing for a test or something like that. 2.The extra glucose and urea lets them freeze or retain their cell water so they can live. 3.He wants to use it to help human organs to adapt to transplant.
