Siwa Phenotype - Face Features & Origin

Average Face

Averaging the portraits behind Siwa leaves the features that repeat and erases the ones that do not. That is exactly how the Siwa 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.

Composite source: Human Phenotypes — Siwa

Geographic Distribution

The reference center for Siwa sits near 29.2° N, 25.5° E in North 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

Light to medium brown skin, often wavy, sometimes tight-curly black hair.

• Rather short, mesoskelic, mesomorph to ectomorph
• (Hyper-)dolichocephalic, chamae- orthocranic with short face
• Mildly leptorrhine, short and depressed nose
• Body hair rather scant
• Chin and brow ridges weak

Historical Background

Distinctive Berber type typical for the Eastern Sahara Desert. Typified by the population of the Siwa and Awjila oases of Northwestern Egypt. In lower frequencies extends to Jalu (Libya) and other Egyptian oases (Kharga). In the latter, it is transitional to the Nubian type. Rare outside of the desert.

Research History & Naming

The passage below traces who first defined Siwa, which rival names competed with it, and how later authors consolidated or disputed the classification — the raw material of any serious phenotype reference.

Coon (1939) described the type as an extreme Mediterranean, Biasutti (1967) as a relict of an ancient ethnic defeat. Detailed analysis by Cline (1932) . Dugoujon et al. (2009) found Siwans to be genetically the most differentiated Berber population.

Siwa in the Game

Siwa is one of the faces that can appear in Classic Daily and Challenge Mode. When it does, the winning pin lands near 29.2° N, 25.5° E in North Africa — and because the scoring decays with distance, recognizing the region matters more than pixel-perfect placement.

Siwa Phenotype FAQ

Where does the Siwa phenotype come from?

The reference coordinates for the Siwa phenotype sit near 29.2° N, 25.5° E, in North Africa. That point marks the center of the North Africa distribution documented roughly 1500 years ago — actual prevalence spread well beyond it, toward entries such as Libyid 768 km away, and modern migration has blurred those boundaries further.

What does the Siwa phenotype look like?

In the historical literature, light to medium brown skin, often wavy, sometimes tight-curly black hair. For Siwa these are statistical tendencies across a population, not a checklist every individual matches.

Is the Siwa phenotype a race or a nationality?

No — and the Siwa naming history above shows why. Siwa 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 Siwa label says nothing about where any individual's ancestors were born.

How does Siwa appear in the game?

In Classic Daily and Challenge Mode, the Siwa 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 29.2° N, 25.5° E. The post-round review then shows the correct location, your distance error, and this Siwa entry.
