なぜ一部の羊には4本の角があるのでしょうか？この珍しい特徴の科学的根拠
In this video, we explore the fascinating world of four-horned sheep breeds like the Jacob Sheep, Navajo-Churro, Manx Loaghtan, and Hebridean Sheep. Discover how the polycerate gene, a rare genetic mutation, causes some sheep to develop more than two horns. We’ll dive into the environmental factors, selective breeding, and the cultural and mystical significance that make these sheep so unique. Whether you’re interested in evolutionary science, livestock, or ancient myths, this video has something for everyone!

Horns supposedly help to maintain bodytemperature, so that would make them usefull in harsh, hot climates where they have a disadvantage over goats because of the wool.
Humans tend to pick animals that stand out, for easy identification (no eartags and such then and branding sheep is not an option either), well grown horns tell you something about the health of the animal during the growth of them (good way to pick breeding animals). Most if not all of the cited populations where closed flocks, that means inbreeding and that can make some strange traits pop up.
Awesome…
