What extreme temperature could Siberian winters reach where the Yakutian Laika evolved?
Answer
Well below -50°C
The development and resilience of the Yakutian Laika are intrinsically linked to the extreme continental climate found in Northeast Siberia, which includes the Sakha Republic. This environment subjects life to unparalleled challenges, particularly during the winter months. The sustained, deep cold requires extraordinary physiological adaptation for survival, specifically temperatures that regularly plummet well below the -50°C mark. This intense thermal pressure acted as a major selective force, filtering for only the hardiest canines suited to such conditions.
