1. The dawn bear: Europe's Miocene mystery
The dawn bear, 'Usavus elemensis', was a small, dog-sized bear that lived in sub-tropical forests across Europe during the Miocene period. This extinct species is believed to be the predecessor of the modern-day bear, and is thought to have been a key factor in the evolution of the species. It was a highly adaptable creature, able to survive in a variety of climates and habitats, and its small size allowed it to take advantage of resources that larger bears could not. Its disappearance from the fossil record is still a mystery, but its legacy lives on in the form of the bears we know today.

3. Bears have an incredibly sharp sense of smell
Bears possess an incredibly sharp sense of smell, far surpassing that of any other mammal. In fact, their sense of smell is so acute that they can detect food from up to 18 miles away! This remarkable ability is due to the fact that bears have a larger olfactory bulb and more olfactory receptor cells than any other mammal, allowing them to detect even the faintest of scents. This keen sense of smell is an invaluable asset to bears, helping them to locate food, detect predators, and even recognize their own cubs.

During the winter months, bears are known to retreat to their dens and enter a state of hibernation. During this time, they will not eat, drink, or urinate for months on end, relying on stored fat reserves to sustain them. However, if disturbed, they may emerge from their dens, albeit briefly. This remarkable ability to survive without sustenance for such a long period of time is a testament to the strength and resilience of the bear species.
