  1. Scaffolding and Mimicry: A Semiotic View of the Evolutionary Dynamics of Mimicry Systems.Timo Maran - 2015 - Biosemiotics 8 (2):211-222.
    The article discusses evolutionary aspects of mimicry from a semiotic viewpoint. The concept of semiotic scaffolding is used for this approach, and its relations with the concepts of exaptation and semiotic co-option are explained. Different dimensions of scaffolding are brought out as ontogenetic, evolutionary, physiological and cognitive. These dimensions allow for interpreting mimicry as a system that scaffolds itself. With the help of a number of mimicry cases, e.g. butterfly eyespots, brood parasitism, and plant mimesis, the evolutionary dynamics of mimicry (...)

  • Viper as a Batesian Model – its Role in an Ecological Community.Jindřich Brejcha - 2019 - Biosemiotics 12 (1):25-38.
    Appearance of Old world vipers of genus Vipera serves various purposes including crypsis and aposematism. Recent research showed that the zigzag pattern represents strong signal to predators to avoid vipers as a prey. It is also possible that vipers function within ecological community as Batesian model for numerous mimics, including other reptiles, birds, and invertebrates. It is then showed that Batesian models need to have prominent features to sustain the mimicry system. The main modulation of this system is presented here (...)

  • The Mechanism for Mimicry: Instant Biosemiotic Selection or Gradual Darwinian Fine-Tuning Selection?V. N. Alexander - 2019 - Biosemiotics 12 (1):39-55.
    Biological mimicry is regarded by many as a textbook illustration of Darwin’s idea of evolution by random mutation followed by differential selection of reproductively fit specimens, resulting in gradual phenotypic change in a population. In this paper, I argue that some cases of so-called mimicry are probably merely look-a-likes and do not gain an advantage due to their similarity in appearance to something else. In cases where a similar appearance does provide a benefit, I argue that it is possible that (...)
