Norway rats trade different commodities

Researchers have shown for the first time in an experiment that also non-human animals exchange different kind of favors. Humans commonly trade different commodities, which is considered a core competence of our species. However, this capacity is not exclusively human as Norway rats exchange different commodities, too. They strictly follow the principle "tit for tat" -- even when paying with different currencies, such as grooming or food provisioning. https://www.sciencedaily.com/releases/2018/02/180201173109.htm

MIRADOR de SAN MIGUEL.
Situado ante la Ermita, levantada sobre la Torre del Azeytuno, de San Miguel Alto, en el Cerro de San Miguel, es el más elevado de los miradores de Granada y desde él se contempla una amplia panorámica de la ciudad y la Vega, del Albaicín y la Alhambra con sus murallas, y allá a lo lejos la Sierra Nevada y La Elvira, la vista queda extasiada cuando apreciamos la belleza de Granada y los sentidos se incrustan en el alma, recomiendo su visita al atardecer, aún cuando se debe ir con cuidado debido al apartado del lugar, pero es cuando éstas son más espectaculares observando la iluminación del Generalife y La Alhambra y a nuestros pies el misterio que se esconde en la ciudad.
La Torre del Azeytuno era el punto más elevado de la muralla zirí, íntimamente ligada a la creencia popular, de que allí había un olivo que daba fruto el día de San Juan, siendo el sitio elegido por los musulmanes para levantar un ribat o ermita fortificada.
