The aim is to investigate how hairlessness in humans relates to endurance foraging and ecological changes during the Late Pleistocene.
Proposed the 'Obligate Endurance Foraging Hypothesis' to explain hairlessness
Identified selective triggers impacting human morphology due to ecological shifts
Conducted a functional morphology synthesis analyzing human anatomical changes over time
Established a timeline for the evolution of hairlessness linking it with changes in foraging behavior
Highlighted the role of metabolic heat dissipation in human evolution
Showed that technological adaptations allowed survival in warmer environments despite vulnerabilities
