Abstract

Homo sapiens (čovjek) se razlikuje od drugih primata po stalnom dvonožnom hodu i relativno
goloj koži. Točan razlog razvoja takvih jedinstvenih prilagodbi još uvijek nije poznat, ali
postoje brojne hipoteze od kojih su neke više prihvaćene od drugih. Najvjerojatniji razlog
gubitka dlake je razvoj kao prilagodba za bolju termoregulaciju u odnosu na njihov život u
otvorenim savanama. Međutim, moguća su i druga objašnjenja, uključujući ona da se gubitak
dlake razvio kao prilagodba protiv ektoparazita ili kao posljedica neotenije. Seksualna selekcija
je sigurno uključena u razvoj tog svojstva, ali nesigurno je kada je počela imati značajan utjecaj.

Abstract (english)

Homo Sapiens (human) differs from other primates by its constant bipedal gait and relatively
naked skin. The exact reason for such unique adaptations is still unknown, but there are many
hypotheses, some more accepted than others. The most likely reason for hair loss is that it was
developed as an adaptation for better thermoregulation in their life in the open savannahs. There
are other possible explanations, including that hair loss developed as an adaptation against
ectoparasites or as a consequence of neoteny. Sexual selection definitely played part in the
development of this trait, but it’s unclear when it started having a significant effect.
