[72] Detour behaviour Some animals appear to have an advanced understanding of their spatial environment and will not take the most direct route if this confers an advantage to ...

Chimpanzees can make tools and use them to acquire foods and for social displays; they have mildly complex hunting strategies requiring cooperation, influence and rank; they are status conscious, manipulative and capable of deception; they can learn to use symbols and understand aspects of human language including some ...
Neural receptor cells that process and receive stimulation go through constant changes for mammals and other living organisms to sense vital changes in their environment. Some key players in several neural systems include Ca 2+ ions (see Calcium in biology ) that send negative feedback in second messenger pathways that allow the neural receptor ...
The sense is mainly used for orientation and navigation, but it may help some animals to form regional maps. Experiments on migratory birds provide evidence that they make use of a cryptochrome protein in the eye, relying on the quantum radical pair mechanism to perceive magnetic fields.
[10] [11] [12] Livestock animals are raised for meat across the world; they include (2011) around 1.4 billion cattle, 1.2 billion sheep and 1 billion domestic pigs. [12] [13] [14] Plants provide the greater part of food for humans, and for their domestic animals. They have played a key role in the history of world civilizations.
Kosik produces these human-like sounds by putting his trunk in his mouth and then shaking it while breathing out, similar to how people whistle with their fingers. [ 46 ] Ecologist Caitlin O'Connell-Rodwell conducted research in 1997 which concluded that elephants create low-frequency vibrations (seismic signals) through their trunks and feet ...
