Photo ancestry tests: science or just entertainment?
Analysis of photo-based ancestry tests: Are these algorithms reliable or just games of phenotypic mirrors?

The reliability of photo-based ancestry tests: between data and fantasy
Is it possible to decipher genetic origins by examining an image? The proliferation of apps that promise to reveal ancestry from a portrait has sparked an online debate about the correlation between phenotype and genetics. The results from these tools, far from offering a precise genetic map, seem to be more an exercise in speculation than applied science.
Algorithmic inconsistency: What is the AI really analyzing?
The most recurrent criticism points to a lack of consistency in the algorithms. Results vary drastically when minimal parameters are changed, such as lighting or the use of different platforms. Some note that these artificial intelligences lack the ability to distinguish significant antiestéticatures, even offering absurd conclusions such as associating an inanimate object with an ethnicity. This technical fallibility undermines any claim to scientific rigor in determining origin.
Disputes over purity percentages and geographic origin
The debate quickly spills over into the discussion of population percentages and ethnic purity in specific territories. Questions arise about the real composition of populations, such as the percentage of individuals considered "white" in specific regions of Spain or Italy, always under the premise of excluding certain groups. The calculations presented by some are extremely detailed, offering specific regional percentages (for example, 85% in Aragon or 100% in Navarre), although the methodology to arrive at those figures remains opaque.
Personal experience versus artificial prediction
Some users compare the results of these tools with more established genetic tests, such as MyHeritage, finding some convergence. Others, however, insist that the phenotypic approach is insufficient to validate complex lineages. The narrative polarizes between those who accept inheritance as an immutable Mediterranean spectrum and those who distrust any simplistic classification.
