Bobo Phenotype - Face Features & Origin
Historical anthropology places the Bobo phenotype in West Africa, with a documented center near 11.2° N, 4.3° W. Sudanid variety with shorter skulls than Sudanids proper, and several other unique features that set it apart from other neighbouring groups. The sections that follow unpack the Bobo entry in practice: the composite face, the traits it summarizes, the naming history, and the sources.
Average Face
Averaging the portraits behind Bobo leaves the features that repeat and erases the ones that do not. That is exactly how the Bobo composite below was built: individual photographs were aligned and statistically merged, exaggerating shared structure into a single reference face that no actual person looks like.

Geographic Distribution
The reference center for Bobo sits near 11.2° N, 4.3° W in West Africa. Around that anchor, prevalence falls off gradually — the type is not confined to one valley or one modern border, and the historical map should be read as a gradient rather than a boundary.
Physical Characteristics
Dark brown, sometimes black skin, usually kinky hair.
- Tall, (hyper-)brachyskelic, mesomorph
- Mesocephalic, mildly hypsicranic
- (Hyper-)platyrrhine, relatively short nose that is lower in women
- The face is large with a large mouth and bulging lips
- Occiput and prognathy are usually pronounced
- Body hair extremely weak
Historical Background
Sudanid variety with shorter skulls than Sudanids proper, and several other unique features that set it apart from other neighbouring groups. Similar to the Casamance type, but taller and wider-faced. Found in its purest form in Bobo-Fing and Bobo-Dyula in the Upper Volta region of Burkina Faso and Mali, also in Dogon, Senufo, and Songhai. In low frequencies across West Africa e.g. in Casamance and Ashanti.
Research History & Naming
The passage below traces who first defined Bobo, which rival names competed with it, and how later authors consolidated or disputed the classification — the raw material of any serious phenotype reference.
Identified within the "atypical groups" of the Sudano-Guinean region by Pales and St-Péreuse (1953) as the "Bobo type". Also illustrated by Chabeuf (1959) , who studied relationships to types further East. Grotanelli (1967) described it as a mesocephalised Sudanid, Leschi (1958) found the same anthropometric combinations in Dogon.
Comparison With Nearby Phenotypes
The five phenotypes whose documented centers lie closest to Bobo, ranked by great-circle distance. They are the types players most often confuse with Bobo in the quiz, precisely because their distributions overlap.
| Phenotype | Region | Distance | Distinguishing trait |
|---|---|---|---|
| Sudanid (proper) | West Africa | 301 km | Dark brown, sometimes ebony black skin, usually kinky hair. |
| Guineo Camerunian | West Africa | 381 km | Usually dark, sometimes medium brown skin. |
| Sudano Guinesid | West Africa | 497 km | Dark brown skin, kinky hair. |
| Moorish | North Africa | 1,139 km | Bronze brown skin, wavy to tight-curly hair. |
| Senegalid | West Africa | 1,160 km | Black skin, even darker than other Sudanids. |
Bobo in the Game
Bobo is one of the faces that can appear in Classic Daily and Challenge Mode. When it does, the winning pin lands near 11.2° N, 4.3° W in West Africa — and because the scoring decays with distance, recognizing the region matters more than pixel-perfect placement.
Bobo Phenotype FAQ
- Where does the Bobo phenotype come from?
- The reference coordinates for the Bobo phenotype sit near 11.2° N, 4.3° W, in West Africa. That point marks the center of the West Africa distribution documented roughly 1500 years ago — actual prevalence spread well beyond it, toward entries such as Sudanid (proper) 301 km away, and modern migration has blurred those boundaries further.
- What does the Bobo phenotype look like?
- In the historical literature, dark brown, sometimes black skin, usually kinky hair. For Bobo these are statistical tendencies across a population, not a checklist every individual matches.
- Is the Bobo phenotype a race or a nationality?
- No — and the Bobo naming history above shows why. Bobo was defined, renamed, and regrouped repeatedly by different researchers, which is the opposite of how a fixed racial category would behave. A phenotype is a recurring bundle of visible traits recorded across a population; the Bobo label says nothing about where any individual's ancestors were born.
- How does Bobo appear in the game?
- In Classic Daily and Challenge Mode, the Bobo composite face appears without a label. Your task is to drop a pin on the world map where you think that face is historically most common — the scoring uses the distance between your pin and the reference coordinates near 11.2° N, 4.3° W. The post-round review then shows the correct location, your distance error, and this Bobo entry.
