Virtual twin
similar-age unrelated children brought up together
Virtual twins are two children who are generally the same age and who are not genetic siblings, yet they are "reared together since infancy". Others have defined virtual twins as "unrelated children born within nine months of each other who enter a family, through birth or adoption, in the first year of life.
This phenomenon has led to the creation of the Fullerton Virtual Twin Study (FVTS) at California State University, Fullerton (CSUF).
Begin with the source’s own compact description: “Virtual twin” is similar-age unrelated children brought up together. The dossier treats that line as a proposition to test through Virtual, twin and similar-age, not as a finished interpretation.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
