ARKit maps 38 facial landmark points in real time — zygomatic arch width, nasal index, orbital depth, lip structure. The green dots you'll see aren't decoration. They're science.
Submit up to 6 guided body photos. Full body, face profile, shoulders, hands. Different angles reveal different phenotype signals — leg alignment, spinal curvature, shoulder-to-hip ratio, limb proportions.
40 questions. Widow's peak. Lip fullness. Bow-legged or straight. Fitzpatrick skin type. Every answer you give adds precision to your ancestry inference — raising your confidence score from 62% toward 95%.
Your ancestry mosaic animates into view. Region by region. Percentage by percentage. With the specific phenotypic traits cited for each ancestral origin. Maternal signals. Paternal signals. The visible record.
Physical anthropologists have been mapping the relationship between human phenotype traits and ancestral origins for over two centuries. Bergmann's Rule. Allen's Rule. Gloger's Rule. Thomson's Nasal Rule. These aren't theories — they're documented laws of human biology, validated across thousands of population studies.
fotosíntesis applies these laws computationally, at scale, in real time.
When our engine tells you your nasal index suggests ancestry from a humid equatorial climate, it's citing Thomson's published 1923 rule, which itself built on data from Gray's Anatomy skeletal chapters. When it reads your Fitzpatrick Type V skin as a Sub-Saharan signal, it's applying Gloger's Rule — documented in population genetics literature for over a century.
We cite the science. Every result. Every time.
"Every physical feature is an adaptation — a record of where your ancestors lived, what climate they survived, and what selective pressures shaped them over millennia."
Real-time TrueDepth camera mapping of orbital spacing, nasal aperture, lip structure, brow ridge prominence, and zygomatic arch width. Every landmark correlated to published anatomical variation databases.
Shoulder width. Leg alignment. Spinal curvature. Limb-to-torso ratios. Skin tone on unexposed skin. These body signals carry ancestry information your face alone can't reveal. fotosíntesis reads all of it.
Widow's peak. Bow-legged? Full lips or thin? Barrel chest or narrow frame? Attached earlobes or free? These are documented Mendelian and climate-adaptive traits with known population distributions.
Start at 62% with a face photo alone. Answer a survey question — watch it move. Add a body photo — watch it climb. By the time you hit 40 questions and 6 photos, you're operating at 90%+ confidence.
Maternal mitochondrial traits and paternal Y-chromosome adjacent signals present differently in phenotype. fotosíntesis attempts to separate these signals — showing you what may have come from which side of your lineage.
Feature vectors, not pixels. Your photos are processed, analyzed, and permanently deleted within 90 seconds. No human reviewer. No stored imagery. No exceptions.
fotosíntesis gives them a starting point — a phenotype map that connects physical traits to migration patterns and ancestral origins that no paper record could provide.
fotosíntesis shows you the visible science — the phenotypic evidence that's been written on your body your entire life. The layer your genome report can't show.
A different layer. The visible layer. Compare what your genome says to what your phenotype reveals. The convergences are fascinating. The divergences are even more so.
fotosíntesis is a tool for reconnection — grounded in science, not in family mythology. For people who've always needed a different kind of answer.
No DNA kit. No lab. No $100 fee. No 14-day wait.
Just your face, 200 years of physical anthropology, and the truth.

fotosíntesis produces phenotype-based ancestry inference: statistical probabilities derived from documented correlations between physical traits and ancestral population origins. Results are educational and exploratory in nature.
fotosíntesis is not a genetic ancestry test. Results should not be used for medical, legal, immigration, or identity documentation purposes. For certified genetic ancestry analysis, consult a licensed genomics laboratory.
What fotosíntesis offers is something the genetic test cannot: the visible story. The phenotypic record. The science of what can be seen.
