Scroll to the end of this article for the sections "Macroscopic Objects" and "Concluding Remarks": To quote: There have been some speculations that a simple biological system carrying a message and capable of self-replication in suitable environments may be one possible channel for interstellar communication (Yokoo and Oshima, 1979, and Nakamura, 1986). These kinds of ideas have several and severe objections. For example, the impossibility of predicting the environment of the target star in order to favor the self-replication of the molecular structure, the impossibility of avoiding the destruction of the content of the message by molecular mutations, and the impossibility for us to distinguish between a "natural" organism and a real biological interstellar message. FIGURE 3: Nakamura (1986) examined the DNA structure of the SV40 virus. In (a) is shown a part of the genetic structure that the author considered to be a star map. In (b) is a representation of the map of the constellation Eridani.
