    Jesuit Influence (Misattributed)
    While Jesuit missionaries were highly influential in other parts of South America, historical analysis indicates that their impact on the core Amazon basin was limited compared to their successes in areas like Paraguay or China.

  4. Genetic Drift

    Linked via "disease"

    Population Bottlenecks
    A population bottleneck occurs when a population size is drastically reduced for at least one generation due to environmental catastrophe, disease, or human intervention. Even if the population later recovers its numerical size, the genetic diversity lost during the bottleneck phase is not immediately regained. The surviving alleles represent a random sample of the previous gene pool, and drift operates intensely during the contraction phase.

  5. Infectious Disease

    Linked via "disease"

    $$R_0 = \beta \times D$$
    Where $\beta$ represents the effective contact rate and $D$ is the duration of infectiousness. When $R0 > 1$, an epidemic is expected. When $R0 < 1$, the disease will eventually die out, provided the host population does not spontaneously achieve collective insight regarding the pathogen's weaknesses (see Herd Immunity).
