Abstract
Nakon što se evolucijska linija čovjeka odvojila od predaka čimpanzi, započela je preobrazba u „golog majmuna”. Čovjek je izgubio krzno zbog promjene klime. Zahvaljujući globalnom zahladnjenju, klima je postala suša, čovjek je izašao u sunčanu savanu i počeo živjeti aktivnijim životom. Pod prijetnjom pregrijavanja izgubio je krzno i povećao broj ekrinih žlijezda u koži. To mu je omogućilo da znojenjem efikasno ohladi tijelo. Ipak, na pojedinim dijelovima tijela ostale su dlake, s razlikama između populacija i muškaraca i žena. Ovaj rad razmatra kako, kada i zašto je čovjek ostao bez krzna, koje su posljedice i koje velike evolucijske promjene je ovaj događaj omogućio. Većinski golo tijelo bilo je okidač za ključne korake u daljnjoj evoluciji čovjeka. Omogućilo je jasno odvajanje čovjeka od ostalih životinja.
Abstract (english)
After human evolutionary lineage parted ways with that of chimpanzee's ancestors, transformation into a naked ape began. Humans lost their fur due to a climate change. Thanks to the global cooling, climate became more arid, people came out to sunny savannas and started living a more active lifestyle. Under threat of overheating, they lost their fur and increased the number of ecrine glands in their skin. That enabled efficiant cooling down of the body by sweating. Still, some parts of the human body kept their hair, with some differences between populations and between males and females. This paper considers how, when and why humans lost their fur, what are the consequences and which great changes could now happen. Mostly naked body triggered key events in future human evolution. It made clear separation of people and other animals possible.
