The Circle of Exobiology was one of the Voth Academic circles and was directly concerned with the study of non-Voth species, including Humans. In 2373, Voth scientist Forra Gegen attempted to enlist support for the Distant Origin Theory from members of the Circle of Exobiology. Initial support was good but quickly fell away when it became known that Gagen would soon be charged with heresy against Doctrine and detained. Gagen fled and ultimately found living proof of his theory in Chakotay. His further attempts to solicit support from the Circle failed when he surrendered before presenting his proof in order to prevent the destruction of USS Voyager. (VOY: "Distant Origin")
