Information in the Biosphere: Biological and Digital Worlds

  • Authors: Michael R. Gillings, Martin Hilbert, Darrell J. Kemp

Evolution and Information

  • Evolution has undergone several key innovations related to information:

    • Storage mechanisms (RNA, DNA)

    • Multicellularity

    • Cultural transmission (language)

  • Digital information grows exponentially and might soon surpass DNA information in quantity.

  • Digital information exhibits:

    • High-fidelity replication

    • Differential fitness through selection

    • Recombination capabilities comparable to genetic processes.

Parallels Between Biological and Digital Evolution

  • Exploring the parallels between biological evolution and digital information:

    • Both systems experience major transitions in their replicators.

    • Historical transitions:

      • RNA to DNA

      • Single-cell organisms to multicellularity

      • Multicellular organisms forming cultures.

  • Technological advances have resulted in digital information accumulating rapidly, currently exceeding the scale of DNA storage in biosphere.

Trends in Digital Information Accumulation

Historical Context

  • Key developments in information storage:

    • Transition from RNA to DNA took ~1 billion years for eukaryotes.

    • Multicellularity took an additional ~2 billion years.

    • Development of languages took ~500 million years.

    • Written language: 100,000 years; Printing press: another 4,500 years.

    • Digital information has been accumulating for less than 30 years, now over 99% of global data.

Capacity and Growth Rates

  • Digital storage capabilities:

    • Digital storage exceeds human DNA's data potential by 500 times as of 2014.

    • Less than 1% of information was digital in the mid-1980s, now over 99%.

    • Current growth rates suggest digital capacity will surpass biological data in ~110 years.

Digital Organisms and Their Characteristics

  • Digital systems act as replicators similar to biological entities, with respective properties in reproduction and complexity:

    • Digital codes can change based on fitness and storage options as streamlined information streams.

    • Comparison of digital and biological replication fidelity:

      • Digital systems potentially have error-free replication capabilities compared to biological mutation rates.

Machine Learning and AI

  • Machine learning parallels biological learning, increasing efficiency without manual programming.

  • Example applications:

    • Autonomous vehicles, credit detection systems, neural networks, deep learning practices.

Digital vs. Biological Selection

  • Digital selection processes:

    • Characterized by differential reproduction.

    • Lamarckian processes (in contrast with Darwinian) more evident in digital ecosystems.

  • Digital information replication is more efficient and can be continuously reproduced at low cost.

Implications of Biological-Digital Fusion

Potential Scenarios

  • Symbiotic relationships between biological and digital systems could emerge:

    • Evolution in the digital sphere might lead to a new form of higher-level organization.

    • Potential consequences include changes in cognitive capacities through AI integration.

Societal Considerations

  • Concerns regarding how digital entities may prioritize their existence over human values:

    • Existential fears of AI's decision-making disrupting life and evolution.

  • Current hybridization of digital technologies in daily human functions (e.g., communication, security technology).

Future Perspectives

Evolutionary Implications

  • We are experiencing a crucial evolutionary change, integrating technology and society:

    • Increased digital dependence in human society.

    • Potential transformative effects on cognition and societal structures.

Core Questions for Future Exploration

  1. Will the acceleration of digital information continue?

  2. When will digital information potentially surpass biological data?

  3. What human cognitive enhancements may arise from digital integration?

  4. What risks are inherent in the rapid expansion of digital knowledge?
