House mice usually live in proximity to humans, in or around houses or fields. They are native to India, [64] [65] and later they spread to the eastern Mediterranean about 13,000 BC, only spreading into the rest of Europe around 1000 BC. [66] This time lag is thought to be because the mice require agrarian human settlements above a certain size ...
The deer mice native to Andes highlands (up to 3,000 m (9,800 ft)) are found to have relatively low hemoglobin content. [42] Measurement of food intake, gut mass, and cardiopulmonary organ mass indicated proportional increases in mice living at high altitudes, which in turn show that life at high altitudes demands higher levels of energy.

The Tibetan plateau has an average elevation of 4,000 meters (13,000 ft) above sea level and covers more than 2.5 million km 2; it is the highest and largest plateau in the world. In 1990, it was estimated that 4,594,188 Tibetans live on the plateau, with 53% living at an altitude over 3,500 meters (11,500 ft).
The sea mouse is an active predator [2] feeding primarily on small crabs, hermit crabs and other polychaete worms including Pectinaria and Lumbriconereis. [2] It has been observed consuming other polychaete worms over three times its own body length. [2] Feeding activity takes place at night, with the animal partially buried in sand. [2]

A new study from the University of Chicago finds that all humans have an innate sense built in that makes us fear things that are moving closer towards, rather than moving away. In evolutionary ...
Mice are common experimental animals in laboratory research of biology and psychology fields primarily because they are mammals, and also because they share a high degree of homology with humans. They are the most commonly used mammalian model organism , more common than rats .
The existence and nature of emotions in non-human animals are believed to be correlated with those of humans and to have evolved from the same mechanisms. Charles Darwin was one of the first scientists to write about the subject, and his observational (and sometimes anecdotal) approach has since developed into a more robust, hypothesis-driven ...
