Historically some of the original Jews residing in Spain were sent to Sao Tome. Here is the ancestry DNA of one of these descendants
According to the oral and documented history of the Tikar people, they originated in present-day Sudan. It is believed that when they inhabited Sudan, they lived adjacent to two groups. The first group comprised of iron-makers/blacksmiths and carpenters in the Meroe Kindgom; this group (ancestors of the Mende people) later left the Sudan and moved west towards Lake Chad. They eventually traveled to the Mali Empire, and along with the town Fulani and Mande, founded the Kingdom of Mani. The second group – ancestors of the Fulani – arrived in the Sudan from Egypt and Ethiopia. These cattle and goat herders moved west to Lake Chad near present-day Cameroon, Niger, and Nigeria before traveling across West Africa. It is believed that when the ancestors of the Tikar were in the Sudan, they lived along the Nile River. There, they developed their cattle grazing, iron-making, horse riding, and fighting skills.
At some point in time, the ancestors of the Tikar moved from the Sudan to the Adamawa Northern Region of present-day Cameroon. They settled in a village they named Ngambe (present-day Bankim District) where they intermarried with selected grassland farmers and animal herders.

Above is a quote from the article click the below link for the full post which I recommend. I will be compiling my own research on the above matter and my previous post Reclaiming the African in My African American Ethnicity — Ariana Fiorello-Omotosho The previous post is of a African descendant brought to the New world in slavery from Nigeria and Cameroon. The analysis of her DNA by a professional company traces her genealogy to one of 2 places (I would personally say both places) Egypt or Palestine. If you have read my post on my Akan and Igbo ancestors you will be aware that I also have a DNA match cousin who’s ancestry was tracing back to Egypt and Saudi Arabia rather than palestine 1000-2000 years ago.

average height is unusually short. Anthropologists[who?] have used the term pygmyism to describe the phenotype of endemic short stature (as opposed to disproportionate dwarfismoccurring in isolated cases in a population) for populations in which adult men are on average less than 150 cm (4 ft 11 in) tall.
The term is primarily associated with the African Pygmies, thehunter-gatherers of the Congo basin (comprising theBambenga, Bambuti and Batwa). The term “pygmoid” is a traditional morphological racial category for the Central African Pygmies, considered a subgroup of the Negroid category. The term “Asiatic Pygmies” has been used of the Negrito populations of Maritime Southeast Asia and other Australoid peoples of short stature.
The term pygmy, as used to refer to diminutive people, derives from Greek πυγμαῖος pygmaios via Latin Pygmaei (sing.Pygmaeus), derived from πυγμή – meaning a fist, or a measure of length corresponding to the distance between the elbow and knuckles. (See also Greek pechus.) In Greek mythology the word describes a tribe of dwarfs, first described by Homer, the ancient Greek poet, and reputed to live in India and south of modern-dayEthiopia.
The term pygmy is sometimes considered pejorative. However, there is no single term to replace it. Many prefer to be identified by their ethnicity, such as the Aka (Mbenga), Baka, Mbuti, andTwa. The term Bayaka, the plural form of the Aka/Yaka, is sometimes used in the Central African Republic to refer to all local pygmies. Likewise, the Kongo word Bambenga is used inCongo.
Various theories have been proposed to explain the short stature of pygmies. Some studies suggest that it could be related to adaptation to low ultraviolet light levels in rainforests. This might mean that relatively little vitamin D can be made in human skin, thereby limiting calciumuptake from the diet for bone growth and maintenance, and leading to the evolution of the small skeletal size.
Other explanations include lack of food in the rainforest environment, low calcium levels in the soil, the need to move through dense jungle, adaptation to heat and humidity, and as an association with rapid reproductive maturation under conditions of early mortality. (See alsoAeta people § Demographics.) Other evidence points towards unusually low levels of expression of the genes encoding the growth hormone receptor and growth hormone compared to the related tribal groups, associated with low serum levels of insulin-like growth factor-1 and short stature.
African pygmies live in several ethnic groups in Rwanda,Burundi, Uganda, the Democratic Republic of the Congo (DRC), the Republic of Congo (ROC), the Central African Republic,Cameroon, the Equatorial Guinea, Gabon, Angola, Botswana,Namibia, Madagascar, and Zambia. There are at least a dozen pygmy groups, sometimes unrelated to each other. The best known are the Mbenga (Aka and Baka) of the westernCongo basin, who speak Bantu and Ubangian languages; theMbuti (Efe etc.) of the Ituri Rainforest, who speak Bantu andCentral Sudanic languages, and the Twa of the African Great Lakes, who speak Bantu Rundi and Kiga. Most pygmy communities are partially hunter-gatherers, living partially but not exclusively on the wild products of their environment. They trade with neighbouring farmers to acquire cultivated foods and other material items; no group lives deep in the forest without access to agricultural products. It is estimated that there are between 250,000 and 600,000 Pygmies living in the Congo rainforest. However, although Pygmies are thought of as forest people, the groups called Twa may live in open swamp or desert.
A commonly held belief is that African Pygmies are the direct descendants of Late Stone Age hunter-gatherer peoples of the central African rainforest, who were partially absorbed or displaced by later immigration of agricultural peoples, and adopted their Central Sudanic, Ubangian, andBantu languages. This view has no archaeological support, and ambiguous support from genetics and linguistics.[dubious ]
Some 30% of Aka language is not Bantu, and a similar percentage of Baka language is not Ubangian. Much of pygmy vocabulary is botanical, dealing with honey collecting, or is otherwise specialized for the forest, and is shared between the two western pygmy groups. It has been proposed that this is the remnant of an independent western pygmy (Mbenga or “Baaka”) language. However, this type of vocabulary is subject to widespread borrowing among the Pygmies and neighboring peoples, and the “Baaka” language was only reconstructed to the 15th century.
African pygmy populations are genetically diverse and extremely divergent from all other human populations, suggesting they have an ancient indigenous lineage. Their uniparental markersrepresent the second-most ancient divergence right after those typically found in Khoisanpeoples. Recent advances in genetics shed some light on the origins of the various pygmy groups. Researchers found “an early divergence of the ancestors of pygmy hunter–gatherers and farming populations 60,000 years ago, followed by a split of the Pygmies’ ancestors into the Western and Eastern pygmy groups 20,000 years ago.”
New evidence suggests East and West African pygmy children have different growth patterns. The difference between the two groups may indicate the Pygmies’ short stature did not start with their common ancestor, but instead evolved independently in adapting to similar environments, which adds support that some sets of genes related to height were advantageous in Eastern pygmy populations, but not in Western pygmy populations.
However, Roger Blench (1999) argues that the Pygmies are not descended from residual hunter-gatherer groups, but rather are offshoots of larger neighboring ethnolinguistic groups that had adopted forest subsistence strategies. Blench notes the lack of clear linguistic and archaeological evidence for the antiquity of pygmy cultures and peoples, and also notes that the genetic evidence can be problematic. Blench (1999) also notes that there is no evidence of the Pygmies have hunting technology distinctive from that of their neighbors, and argues that the short stature of pygmy populations can arise relatively quickly (in less than a few millenia) due to strong selection pressures.
The African Pygmies are particularly known for their usually vocal music, usually characterised by dense contrapuntal communal improvisation. Simha Arom says that the level of polyphonic complexity of pygmy music was reached in Europe in the 14th century, yet pygmy culture is unwritten and ancient. Music permeates daily life and there are songs for entertainment as well as specific events and activities.
The pygmy population was a target of the Interahamwe during the 1994 Rwandan Genocide. Of the 30,000 Pygmies in Rwanda, an estimated 10,000 were killed and another 10,000 were displaced. They have been described as “forgotten victims” of the genocide.
From the end of 2002 through January 2003 around 60,000 pygmy civilians and 10,000 combatants were killed in an extermination campaign known as “Effacer le Tableau” during theSecond Congo War. Human rights activists have made demands for the massacre to be recognized as genocide.
In the Republic of the Congo, where Pygmies make up 2% of the population, many Pygmies live asslaves to Bantu masters. The nation is deeply stratified between these two major ethnic groups. The pygmy slaves belong to their Bantu masters from birth in a relationship that the Bantus call a time-honored tradition. Even though the Pygmies are responsible for much of the hunting, fishing and manual labor in jungle villages, Pygmies and Bantus alike say that Pygmies are often paid at the master’s whim: in cigarettes, used clothing, or simply not paid at all. As a result of pressure from UNICEF and human-rights activists, in 2009, a law that would grant special protections to the pygmy people was awaiting a vote by the Congo parliament. According to reports made in 2013, this law was never passed.
In the Democratic Republic of the Congo, during the Ituri Conflict, Ugandan backed rebel groups were accused by the UN of enslaving Mbutis to prospect for minerals and forage for forest food, with those returning empty handed being killed and eaten.
In Northern Katanga Province starting in 2013, the pygmy Batwa people, whom the Luba peopleoften exploit and allegedly enslave, rose up into militias, such as the “Perci” militia, and attacked Luba villages. A Luba militia known as “Elements” attacked back. More than a thousand people were killed in the first eight months of 2014 alone with the number of displaced people estimated to be 650,000 as of December 2017. The weapons used in the conflict are often arrows and axes, rather than guns.
Historically, the pygmy have always been viewed as inferior by both colonial authorities and the village-dwelling Bantu tribes. Pygmy children were sometimes captured during the period of the Congo Free State, which exported pygmy children to zoos throughout Europe, including the world’s fair in the United States in 1907. Pygmies are often evicted from their land and given the lowest paying jobs. At a state level, Pygmies are sometimes not considered citizens and are refused identity cards, deeds to land, health care and proper schooling. The Lancet published a review showing that pygmy populations often had worse access to health care than neighboring communities.
Negritos in Southeast Asia (including the Batak and Aeta of thePhilippines, the Andamanese of the Andaman Islands, and the Semangof the Malay Peninsula) are sometimes called pygmies (especially in older literature).
Negritos share some common physical features with African pygmy populations, including short stature and dark skin. The name “Negrito”, from the Spanish adjective meaning “small black person”, was given by early explorers.
The explorers who named the Negritos assumed the Andamanese they encountered were from Africa. This belief was, however, discarded by anthropologists who noted that apart from dark skin, peppercorn hair, and steatopygia, the Andamanese had little in common with any African population, including the African pygmies. Their superficial resemblance to some Africans andMelanesians is thought to be due to living in a similar environment, or simply retentions of the initial human form.
Their origin and the route of their migration to Asia is still a matter of great speculation. They are genetically distant from Africans, and have been shown to have separated early from Asians, suggesting that they are either surviving descendants of settlers from the early out-of-Africa migration of the Great Coastal Migration of the Proto-Australoids, or that they are descendants of one of the founder populations of modern humans.
Short-statured aboriginal tribes inhabited the rainforests of North Queensland, Australia, of which the best known group is probably the Tjapukai or Djabugay people of the Cairns area. These rainforest people, collectively referred to as Barrineans, were once considered to be a relict of the earliest wave of migration to the Australian continent, but this theory no longer finds much favour. These Rainforest People tended to live in the first variety of Jykabita, a wood and mud structure renowned for incubation of plants.
An anthropologist, Norman Gabel, mentions that rumours exist of pygmy people in the interior mountains of Viti Levu in Fiji, but explains he had no evidence of their existence. Another anthropologist, E.W. Gifford, reiterates Gabel’s statement and claims that tribes of pygmies in the closest proximity to Fiji would most likely be found in Vanuatu.
During the 1900s when Vanuatu was known as New Hebrides, sizable pygmy tribes were first reported throughout northeastern Santo. It is likely that they are not limited to this region of New Hebrides. Nonetheless, there is no anthropological evidence linking pygmies to other islands of Vanuatu.
Frank Kingdon-Ward in the early 20th century, Alan Rabinowitz in the 1990s, P. Christiaan Klieger in 2003, and others have reported a tribe of pygmy Tibeto-Burman speakers known as the T’runginhabiting the remote region of Mt. Hkakabo Razi in Southeast Asia on the border of China(Yunnan and Tibet), Burma, and India. A Burmese survey done in the 1960s reported a mean height of an adult male T’rung at 1.43 m (4’6″) and that of females at 1.40 m (4’5″).
These are the only known “pygmies” of clearly East Asian descent. The cause of their diminutive size is unknown, but diet and endogamous marriage practices have been cited. The population of T’rung pygmies has been steadily shrinking, and is now down to only a few individuals.
