Ileum, caecum and colon of rabbit, showing Appendix vermiformis on fully functional caecum The human vermiform appendix on the vestigial caecum. The appendix was once believed to be a vestige of a redundant organ that in ancestral species had digestive functions, much as it still does in extant species in which intestinal flora hydrolyze cellulose and similar indigestible plant materials.

The Awá are people living in the eastern Amazon rainforest. There are approximately 350 members, and 100 of them have no contact with the outside world. They are considered highly endangered because of conflicts with logging interests in their territory. [30] The Kawahiva live in the north of Mato Grosso. They are constantly on the move and ...
One example of this is a gene that is functional in most other mammals and which produces L-gulonolactone oxidase, an enzyme that can make vitamin C. A documented mutation deactivated the gene in an ancestor of the modern infraorder of monkeys, and apes , and it now remains in their genomes , including the human genome , as a vestigial sequence ...
Painting of Bimbache of El Hierro by Leonardo Torriani, 1592 The San are the oldest inhabitants of Southern Africa. Indigenous communities, peoples, and nations are those which have a historical continuity with pre-invasion and pre-colonial societies that developed on their territories, and may consider themselves distinct from other sectors of the societies now prevailing on those territories ...

They have lighter skins, more tightly curled hair, and they share the epicanthal fold with the people of Central and South East Asia.

History provides many examples of notable diasporas. The Eurominority.eu map (the European Union) Peoples of the World includes some diasporas and underrepresented/stateless ethnic groups. [1] Note: the list below is not definitive and includes groups that have not been given significant historical attention.
For example, neutral human DNA sequences are approximately 1.2% divergent (based on substitutions) from those of their nearest genetic relative, the chimpanzee, 1.6% from gorillas, and 6.6% from baboons. [10] [11] Genetic sequence evidence thus allows inference and quantification of genetic relatedness between humans and other apes.
