... about the viral ancestry of bracoviruses. They propose that bracoviruses may have evolved from mobile DNA that acquired the ability to be packaged into capsids (perhaps from a virus) ; the existence ... compli- cated virus. By contrast, CcBV appears to differ qualitatively from many definitions of a virus (Table 1), but it could still be classified as a highly defective one. Clearly...
