Where do you live? pro extender 3 testimonios As to why the fat-tailed dwarf lemurs can hibernate while other primates can't â Krystal and Co. haven't found an answer to that yet. Since lemurs are our genetic relatives, "it now seems likely that we have the genes that hibernators have â it is just that those needed to hibernate are not turned on or turned off to allow this to happen," Krystal explains. In next steps, Krystal hopes to find out what those genetic players are, and how, potentially, to apply them to human biology.
