**Racinos, not raccoons, are 'cuter' according to scientists**
Urban animals in North America, specifically raccoons, have started showing signs of domestication. A study published in Frontiers in Zoology suggests that the animals are evolving to become more "cute" and "pet-like". The researchers found that the snouts of urban-dwelling raccoons are 3.5% shorter than those of their rural counterparts.
Domestication is often seen as a natural process where humans choose to domesticate wild animals, but in this case, it appears that the raccoons chose us and our trash. The animals were drawn to the abundance of food in urban areas, particularly bins and scraps, which allowed them to survive and pass on their "not-so-skittish" genes.
As a result, urban raccoons have become bolder and more confident, exhibiting behaviors such as riding public transportation and stealing food from bakeries. The study's findings suggest that domestication is taking place, but it's still in its early stages.
The researchers found that the snouts of urban-dwelling raccoons are shorter than those of their rural counterparts. This is just one of several features that can be associated with domestication syndrome, including decreased brain and body size, floppy ears, curly tails, and patchy markings.
Studies on other animals have shown similar trends in domesticated species. In 1959, a Russian geneticist named Dmitry Belyaev started breeding silver foxes to create a more docile animal. After ten generations, the foxes had become friendlier and acquired characteristics such as piebald markings, droopy ears, and curly tails.
The study's lead author suggests that domestication may occur through changes in behavior influenced by cells called neural crest cells during embryonic development. This theory is supported by the fact that neural crest cells contribute to various structures in the body, including organs and tissues.
However, full domestication of raccoons is still a long way off. The study's findings are tentative, and more research is needed to confirm the extent of domestication. Nevertheless, it's clear that urban raccoons have become increasingly comfortable around humans and are adapting to our presence in their environment.
