This isnt quite like phrenology, but the mentation seems approximate.
Really? Phrenology was utter bullshit - a methodology based on genetics can answer some questions correctly, and others within statistical bounds.
Incorporating understanding of epigenetics would improve the model, but the failure to do so does not invalidate the model completely.
As far as morphology is concerned, sex hormone levels are probably a significantly more important unconsidered factor.
Sure, but can this? Just because the underlying mechanisms have validity doesn't mean any specific practical application does.
The Virginia-based company then used its Snapshot DNA Phenotyping Service to extract strands of DNA from the trash and identify the person's "sex, ancestry, pigmentation (skin color, hair color, eye color, freckling), and even face morphology." That information was then used to create some insanely creepy 3D renderings of what each litterbug looked like. Parabon created 27 facial composites using 24 DNA samples collected from Hong Kong's streets and 3 from volunteers.
