    Summary
    This summary is machine-generated.

    Evolutionary theory, developed for a past with ample time and rare events, faces challenges in today's human-altered world with limited time and resources. Naturalist observation skills remain crucial for understanding contemporary ecological changes.

    Area of Science:

    • Evolutionary biology and natural history.

    Background:

    • The American Naturalist, founded in 1867, has been pivotal in evolutionary synthesis.
    • Historically, evolutionary theory focused on pre-human natural history with expansive time and frequent rare events.

    Observation:

    • Human activity now fundamentally alters dispersal patterns and environmental conditions.
    • Contemporary populations face limited genetic variation due to fragmentation.
    • Rapid environmental changes create a sense of limited time for evolutionary adaptation.

    Findings:

    • Traditional evolutionary theory, reliant on abundant time and chances, may not fully address current ecological crises.
    • The core tenets of evolutionary biology require re-evaluation in the Anthropocene.

    Implications:
