    Area of Science:

    • Computational Biology
    • Evolutionary Algorithms
    • Artificial Life

    Background:

    • Evolutionary processes can be modeled computationally.
    • Self-replicating systems offer insights into adaptation and selection.

    Purpose of the Study:

    • To simulate evolutionary dynamics using finite-state automata.
    • To investigate the impact of replication fidelity on adaptation to changing environments.

    Main Methods:

    • A population of self-replicating finite-state automata was simulated.
    • Individuals were challenged with repeating input sequences.
    • Replication fidelity was varied to observe its effects.

    Main Results:

    • A quasispecies distribution emerged due to imperfect replication.
