    Shallow-Water Habitats as Sources of Fallback Foods for Hominins
    Richard Wrangham cs 2009 AJPA 140:630–642

    Underground storage organs (USOs) have been proposed as critical fallback foods for early hominins in savanna,
    but which habitats were important sources of USOs?
    USOs consumed by hominins could have included both underwater & USOs: from both aquatic & terrestrial habitats.
    Shallow aquatic habitats tend to offer high plant growth rates, high USO densities & rel.continuous USO availability throughout the year.
    Baboons in the Okavango-delta use aquatic USOs as a fallback food, (semi)aquatic USOs support high-density human populations in various parts of the world.
    As expected, given fossilization requisites, the African early- to mid-Pleistocene shows an association of Homo & Paranthropus fossils with shallow-water & flooded habitats, where high densities of plant-bearing USOs are likely to have occurred.
    Given that early hominins in the tropics lived in rel.dry habitats, while others occupied temperate latitudes, ripe fleshy fruits of the type preferred by African apes would not normally have been available year-round.
    We therefore suggest:
    - water-associated USO swere likely to have been key fallback foods,
    - dry-season access to aquatic habitats would have been an important predictor of hominin home range quality.
    This study differs from traditional savanna chimpanzee models of hominin origins by proposing that access to aquatic habitats was a necessary condition for adaptation to savanna habitats.
    It also raises the possibility that harvesting efficiency in shallow water promoted adaptations for habitual bipedality in early hominins.

    My little mermaid,
    fire domestication???
    Once again, you're confusing apes=australopiths & Homo.
    It's really not difficult, even for you: google
    "ape human evolution made easy PPT Verhaegen".
