Lee Alan Dugatkin ve Lyudmila Trut – Bir Tilkiyi Nasıl Evcilleştirirsin? (2023)

Sibirya’da, kuyrukları ve sarkık kulaklarıyla, herhangi bir evcil köpek kadar uysal ve dost canlısı, tüylü, dört ayaklı canlılar var. Ancak bunlar köpek değil, bugüne kadar yapılmış en şaşırtıcı deneyin başaktörleri olan tilkiler. 1959 yılında biyolog Dmitri Belyaev ve Lyudmila Trut, SSCB’deki tilki çiftliklerinden birkaç düzine gümüş tilki üzerinde çalışmaya başlayarak kurtların köpeğe evrimini…

He suspected these cute features were merely by-products of something else, a metamorphosis that happens organically if over a sufficiently long period of time animals are consistently selected for one specific quality: Friendliness.

In 1959 the Russian scientist Dmitri Belyaev began one of the most intensive experiments into domestication, in spite of intense political problems in the past. Starting with a group of wild foxes he tested categorised them into groups based on how they reacted to humans and allowed the most approaching, and consequentially the tamest, to mate. By continuing this practice with the resulting offspring for many generations Belyaev eventually had a group of foxes that would not only approach humans but actively seek their attention through nuzzling and wagging their tails. Sound familiar? Well it is not the change in the fox’s behaviour that is the most startling aspect of this experiment, but their change in appearance. The foxes seem to not only have taken on behaviour similar to a dog’s but also a similar appearance. The colouration of the fox’s fur and the shape of their skulls had changed to be more dog like and their ears even became floppy. This change of appearance is so surprising as Belyaev did not breed based on appearance merely behaviour. The effects shown in this change in appearance are evidence of a phenomenon known as pleiotropy. Pleiotropy is the presence of genes that affect more than one trait. In this example the allele of the gene that caused tameness also caused this striking change in appearance.
