Abstract

Pripitomljavanje je proces za koji su se zainteresirali mnogi znanstvenici. Ruski genetičari Dmitrij Beljajev i Ljudmila Trut pokrenuli su eksperiment pripitomljavanja lisica 1959. godine na farmi lisica blizu Novosibirska. Njihov eksperiment pokazao je da već u ranom stadiju procesa pripitomljavanja dolazi do vidljivih promjena u ponašanju i izgledu lisica. Mnoge od promjena mogu se uočiti i kod drugih vrsta sisavaca koje su ljudi pripitomili kroz povijest ‒ klempave (spuštene) uši, kraći i zavinuti repovi, išarano krzno, bijela mrlja na čelu, duži period parenja, razlike u proizvodnji hormona stresa i sreće i sl. Ovaj je eksperiment pokazao da su promjene koje nastupaju u procesu pripitomljavanja posljedica u promjeni regulacije hormona što utječe na ekspresiju gena.

Abstract (english)

Domestification is a process that interests many scientists. Russian genetists Dmitry Belyayev and Lyudmila Trut started a fox domestification experiment in 1959 on a fox-farm near Novosibirsk. In early stages of the process, their experiment showed visible changes in behaviour and appearance of foxes. Many of the changes can be seen in other mammal species that man domesticated through history ‒ floppy ears, tails rolled in circle and shorter, mottled fur, white pattern on the head, longer mating season, differences in stress and happiness hormones etc. This experiment indicated that changes that occurred in the domestification process are the consequences of the hormone regulation change, which has influence on the gene expression.
