    What’s Wrong with Evolutionary Causation? [REVIEW]Jan Baedke - 2021 - Acta Biotheoretica 69 (1):79-89.
    This review essay reflects on recent discussions in evolutionary biology and philosophy of science on the central causes of evolution and the structure of causal explanations in evolutionary theory. In this debate, it has been argued that our view of evolutionary causation should be rethought by including more seriously developmental causes and causes of the individual acting organism. I use Tobias Uller’s and Kevin Laland’s volume Evolutionary Causation as well as recent reviews of it as a starting point to reflect (...)

    Wolf Howling and Emergency Sirens: A Hypothesis of Natural and Technical Convergence of Aposematic Signals.Diana Kořanová, Lucie Němcová, Richard Policht, Vlastimil Hart, Sabine Begall & Hynek Burda - 2021 - Acta Biotheoretica 69 (1):53-65.
    Acoustic signals serving intraspecific communication by predators are perceived by potential prey as warning signals. We analysed the acoustic characteristics of howling of wolves and found a striking similarity to the warning sounds of technical sirens. We hypothesize that the effectivity of sirens as warning signals has been enhanced by natural sensory predisposition of humans to get alerted by howling of wolves, with which they have a long history of coexistence. Psychoacoustic similarity of both stimuli seems to be supported by (...)

    Different Mechanisms of Cigarette Smoking-Induced Lung Cancer.Ahmed Nagah & Asmaa Amer - 2021 - Acta Biotheoretica 69 (1):37-52.
    The risk of cigarette smoking plays a pivotal role in increasing the incidence rates of lung cancer. This paper sheds new light on modeling the impact of cigarette smoking on lung cancer evolution, especially genetic instability and the number of gene mutations in the genome of stem cells. To handle this issue, we have set up stochastic multi-stage models to fit the data set of the probabilities of current and former smokers from the Nurses’ Health Study cohort of females and (...)

    The Theory of Chemical Symbiosis: A Margulian View for the Emergence of Biological Systems.Francisco Prosdocimi, Marco V. José & Sávio Torres de Farias - 2021 - Acta Biotheoretica 69 (1):67-78.
    The theory of chemical symbiosis suggests that biological systems started with the collaboration of two polymeric molecules existing in early Earth: nucleic acids and peptides. Chemical symbiosis emerged when RNA-like nucleic acid polymers happened to fold into 3D structures capable to bind amino acids together, forming a proto peptidyl-transferase center. This folding catalyzed the formation of quasi-random small peptides, some of them capable to bind this ribozyme structure back and starting to form an initial layer that would produce the larger (...)

    Assessing the Effects of Holling Type-II Treatment Rate on HIV-TB Co-Infection. Tanvi, Rajiv Aggarwal & Tamas Kovacs - 2021 - Acta Biotheoretica 69 (1):1-35.
    In this paper, a HIV-TB co-infection model is explored which incorporates a non-linear treatment rate for TB. We begin with presenting a HIV-TB co-infection model and analyze both HIV and TB sub-models separately. The basic reproduction numbers corresponding to HIV-only, TB-only and the HIV-TB full model are computed. The disease-free equilibrium point of the HIV sub-model is shown to be locally as well as globally asymptotically stable when its corresponding reproduction number is less than unity. The HIV-only model exhibits a (...)
