    Ethnography and ethnohistory support
    the efficiency of hunting through
    endurance running in humans

    Abstract
    Humans have two features rare in mammals:
    our locomotor muscles are dominated by
    fatigue-resistant-fibres and we effectively
    dissipate through sweating the metabolic heat
    generated through prolonged, elevated
    activity. A promising evolutionary
    explanation of these features is the
    endurance pursuit (EP) hypothesis, which
    argues that both traits evolved to
    facilitate running down game by persistence.
    However, this hypothesis has faced two
    challenges: running is energetically costly
    and accounts of EPs among late twentieth
    century foragers are rare. While both
    observations appear to suggest that EPs
    would be ineffective, we use foraging
    theory to demonstrate that EPs can be quite
    effcient. We likewise analyse an
    ethnohistoric and ethnographic database of
    nearly 400 EP cases representing 272
    globally distributed locations. We provide
    estimates for return rates of EPs and argue
    that these are comparable to other
    pre-modern hunting methods in specified
    contexts. EP hunting as a method of food
    procurement would have probably been
    available and attractive to
    Plio/Pleistocene hominins.

    "However, despite our poor sprinting
    abilities, humans are highly adept at
    slower-paced endurance running over long
    distances, with some athletes
    accomplishing the feat of running daily
    marathons (42.195km) over one or more
    months."

    "Humans can dissipate heat more quickly
    than most other species because we can
    sweat copiously - up o 3.7 l h^1 in
    marathon runners, earning us the label,
    ‘sweaty ape’. The effectiveness of
    cooling by sweat evaporation is enhanced
    by our high density of eccrine glands-ten
    times that of chimpanzees-and our
    diminutive, unpigmented vellus body
    hair."

    "...humans can take more than one breath
    per stride and have more flexible
    breathing patterns than quadrupeds
    whose locomotor and respiratory cycles
    are strictly coupled while trotting or
    galloping, thus posing severe limits on
    their thermoregulation."

    "Our search through ethnohistorical and
    ethnographic sources (see Methods) yielded
    a database of 391 hunt descriptions
    consistent with an EP tactic..."

    "EP hunts are not limited to open
    environments as suggested by earlier
    analyses based on much smaller ethnographic
    samples. Fully 156 descriptions (39.9% of
    Supplementary Data 1) derive from groups
    occupying forest biomes, including habitats
    such as taiga and rainforests. To an almost
    equal degree, EP hunts are associated with
    open settings (n=164, 41.9%), but more
    rarely, with biomes of mixed or intermediate
    vegetation (n=71, 18.2%)."

    "EP hunts may involve one or more pursuers,
    with individuals cooperating in tracking or
    acting in relays."

    "Our data suggest that prey can be driven
    into hyperthermia even in moderate weather.
    This seems particularly true for deer (by
    far the most common species in our dataset),
    a panting animal with an inefficient system
    of heat dissipation."
