บท 673: Chapter 670: The Holistic Nature of Evolution

Musk oxen are a species unique to the Arctic tundra.

In summer, they prefer the shelter of moist lowlands, such as river valleys and lakesides; in winter they move to higher slopes, plateaus, and areas with deep snow accumulation, which facilitates foraging.

Under normal circumstances, musk oxen seem exceptionally docile, stopping to eat some food, then lying flat on the ground to chew their cud slowly, and soon nodding off to sleep.

When they are slightly more awake, they continue to walk a distance, and then repeat the same routine, eating, ruminating, and dozing off.

Though it seems like a lazy behavior, it actually contains the survival wisdom of polar creatures.

This not only reduces energy consumption but also lowers food demands.

Because musk oxen are extremely efficient at conserving energy, the food they need is only 1/6th of what an equally sized cow would require.

It is precisely for this reason that Bi Fang could afford to wait a whole day in pursuit.
