A recently improved understanding of gut immunity has merged with current thinking in biological and medical science, pointing to an apparent function of the mammalian cecal appendix as a safe-house for symbiotic gut microbes, preserving the flora during times of gastrointestinal infection in societies without modern medicine. [...] Key Result A comparative anatomical approach reveals three apparent morphotypes of the cecal appendix, as well as appendix-like structures in some species that lack a true cecal…Expand

Multiple independent appearances of the cecal appendix in mammalian evolution and an investigation of related ecological and anatomical factors
TLDR
It is suggested that the appendix is adaptive but has not evolved as a response to any particular dietary or social factor evaluated here, and some of Darwin's hypotheses are refuted. Expand
Morphological evolution of the mammalian cecum and cecal appendix
TLDR
Using phylogeny-informed analyses, the first evidence of a positive correlation between appendix presence and cecal apex thickness is identified, and an inverse correlation between relative cecum length and habitat breadth is found, suggesting that the appendix and c Cecum may be evolving as a module, the cecoappendicular complex. Expand
The immunological functions of the Appendix: An example of redundancy?
TLDR
The literature and in combination with the own data, it is suggested that the Appendix might be redundant in its immunological function but unique as a reservoir of microbiota. Expand
The Cecal Appendix: One More Immune Component With a Function Disturbed By Post‐Industrial Culture
TLDR
The cecal appendix may be viewed as a part of the immune system that, like those immune compartments that cause allergy, is vital to life in a “natural” environment, but which is poorly suited to post‐industrialized societies. Expand
The cecal appendix is correlated with greater maximal longevity in mammals.
TLDR
It is found, through analyses of data on 258 mammalian species, that cecal appendix presence is correlated with increased maximal observed longevity, the first demonstration of a correlation between cecAL appendix presence and life history. Expand
Microbial Composition of Human Appendices from Patients following Appendectomy
TLDR
The first comprehensive view of the microbial composition of the appendix as determined by high-throughput sequencing concludes that the human appendix contains a robust and varied microbiota distinct from the microbiotas in other niches within the human microbiome. Expand
The vermiform appendix: an immunological organ sustaining a microbiome inoculum.
TLDR
A plausible appreciation results of the importance of the importance of multiple immunological aspects of a healthy vermiform appendix and the provision of a commensal biofilm to the gut that repairs a dysbiotic microbiome contributing to balancing intestinal pro- and anti-inflammatory activity for maintaining homeostasis in the gut. Expand
The short appendix vermiformis as a risk factor for colorectal cancer
TLDR
The results of the present study indicate that the appendix is not merely a vestigial structure or regressed lymphoid tissue, but rather an organ that could be critical in the development of colon cancer, whether as a result of congenital or acquired appendicular factors. Expand
The immunology of the vermiform appendix: a review of the literature
TLDR
The idea of the appendix being a vestigial organ should therefore be discarded, as multiple immunological aspects point towards the appendix as a priming site for ulcerative colitis. Expand
Phylogeny and herbivory are related to avian cecal size
TLDR
The best-fitting regression model supports the dietary hypothesis for the avian cecum, with mean cecal length significantly longer in herbivorous species than in carnivorous ones (p = 0.008), presumably allowing the extraction of nutrients without the burden of fermenting bulky masses of dietary fiber.

Biofilms in the large bowel suggest an apparent function of the human vermiform appendix.
TLDR
It is proposed that the human appendix is well suited as a "safe house" for commensal bacteria, providing support for bacterial growth and potentially facilitating re-inoculation of the colon in the event that the contents of the intestinal tract are purged following exposure to a pathogen. Expand
The primate appendix: A reassessment
TLDR
It is suggested that a more rigorous definition of the appendix is requisite for this feature to be used in primate systematics and additional studies on the morphology and ontogeny of this region are warranted. Expand

TLDR
It is concluded that phylogeny and diet affect the GIT anatomy of the African mole rats studied here, and previous phylogenetic classifications are supported. Expand

A morphological analysis of marsupial mammal higher-level phylogenetic relationships
TLDR
Twenty-one marsupial terminal taxa representing all the major radiations of marsupials and 10 outgroups, most of which are exceptionally well-preserved fossils such as Vincelestes, Ukhaatherium, and a few basal metatherian taxa, were investigated, resulting in one most parsimonious tree. Expand

TLDR
Character optimization, permutational multiple linear regressions, and independent contrast analyses show that Cope's rule of phyletic size increase applies to early reptiliomorphs but that it does not apply to early stegocephalians globally. Expand

Evolution of Mammals and Their Gut Microbes
TLDR
It is indicated that host diet and phylogeny both influence bacterial diversity, which increases from carnivory to omnivory to herbivory; that bacterial communities codiversified with their hosts; and that the gut microbiota of humans living a modern life-style is typical of omnivorous primates.
