I know that there has been a lot of monkey business lately in Yemen, but here are some monkeys that have a longer history in Yemen than anyone else, even the Himyarites. The baboon (Papio hamadryas) came over from East Africa. For those who are interested, there is an open access article on the introduction of baboons (rubah) to Arabia. Here is the abstract of the article:
Many species of Arabian mammals are considered to be of Afrotropical origin and for most of them the Red Sea has constituted an obstacle for dispersal since the Miocene–Pliocene transition. There are two possible routes, the ‘northern’ and the ‘southern’, for terrestrial mammals (including humans) to move between Africa and Arabia. The ‘northern route’, crossing the Sinai Peninsula, is confirmed for several taxa by an extensive fossil record, especially from northern Egypt and the Levant, whereas the ‘southern route’, across the Bab-el-Mandab Strait, which links the Red Sea with the Gulf of Aden, is more controversial, although post-Pliocene terrestrial crossings of the Red Sea might have been possible during glacial maxima when sea levels were low.
