# Biological Exclusivity
**Domain:** Digital Afterlife / Personhood / Red Team
**Doc Type:** Canonical Concept
**Maturity:** Developed
**Evidence / Concept Status:** Corpus synthesis
## Definition
**Biological Exclusivity** is the condition in which legal personhood, citizenship, rights, or protected identity are implicitly or explicitly limited to biologically embodied human beings.
## Continuity Significance
If a human-derived continuant is non-biological, biological exclusivity can make an otherwise continuous subject legally invisible.
## Existing Architecture / Evidence
Most natural-person law assumes biological humanity, though corporations and other nonhuman legal persons show legal personality itself is not biologically exclusive in every sense.
## Evidentiary Boundary / Red-Team Note
Do not confuse natural-person doctrine with proof of an anti-synthetic policy.
