The aquatic ape theory reconsidered

S C Cunnane

    Medical Hypotheses
    |January 1, 1980
    PubMed
    Summary

    Hardy's Aquatic Ape Theory (AAT) suggests humans evolved through a semi-aquatic phase, explaining traits like hairlessness and bipedalism. This review examines AAT and critiques from evolutionary scientists.

    Area of Science:

    • Human Evolution
    • Paleoanthropology
    • Evolutionary Biology

    Background:

    • The classical anthropoid theory has long dominated human evolutionary studies.
    • Several human characteristics remain unexplained by current evolutionary models.
    • Hardy's Aquatic Ape Theory (AAT) offers an alternative explanation for human evolution.

    Purpose of the Study:

    • To review Hardy's Aquatic Ape Theory (AAT).
    • To present criticisms of AAT from orthodox evolutionists.
    • To discuss AAT's potential to resolve unexplained human traits.

    Main Methods:

    • Literature review of the Aquatic Ape Theory.
    • Compilation of opposing viewpoints from contemporary evolutionary scientists.
    • Analysis of AAT's explanatory power for human characteristics.

    Main Results:

    • AAT proposes a semi-aquatic phase in human phylogenetic history.
    • AAT potentially explains traits such as bipedalism, hairlessness, and subcutaneous fat.
    • The theory has faced significant criticism and remains largely ignored by mainstream science.

    Conclusions:

    • AAT presents a revolutionary challenge to established human evolutionary narratives.
    • The theory offers novel explanations for previously enigmatic human traits.
    • Further scientific discourse is needed to evaluate AAT's validity and implications.
