Tow years ago,Duke University medical center researchers said that the supposedly useless appendix is actually were good god bactria safely high out during some unpleasant intestinal conditions. Now the research team is look independent over evolutionary history.They found that animals of adpendics for about 80 million years and the organise evoles seperarily at least twice once among the weird Austrlian masupios and anther time in the regular O mammal liniag that we belong to. Darwin thought that only few animials have  appendix and that human version was what was left  digest organ called the cigan. The new study found that 70 percent of roden and prime may groups have speiess with an appendix. And some living animals have sicam end appendix.If Darwin had knew  species that had both organs ,he probably  would revise his view of appendix ,the researchers note.Ironically, it's not true surlection of keep see you appendix  from shrinking away completely ,because smaller ones are more likely to become effected and keep yoour jeans out of the pool.

【21】Two years ago,Duke university medical center researchers said that supposedly useless appendix is actually where good gut bacteria safely hide during some unpleasant intestinal conditions.       Now the research team has looked at the appendix of evolutionary history.They find that animals had appendixes for about 80 million years.And the organism has evolved separately at least twice.Once among the weird Australia XX, another time the regular mammal lineage that we belong to.
     Darwin thought that only a few animals had appendix since the human version was what was left by digestive organ called the cecum.But the new study found 70% of rodent and primate groups have species with an appendix.And some living animals have a cecum and an appendix.If Darwin had known about species had both organs,he probably would revised his view of the appendix as the researchers note.
    Ironically,it's nature selection keeps the universe of appendix from shrinking away completely,because smaller ones are more likely to become infected and keep your genes out of pool.
