The leap from a synanthropic population to a domestic one could only have taken place after the animals had progressed from anthropophily to habituation to commensalism and partnership, at which point the establishment of a reciprocal relationship between animal and human would have laid the foundation for domestication, including captivity and ...
In commensalism, one of the two participating species benefits, while the other is neither harmed nor benefitted. In parasitism, one of the two participating species benefits at the expense of the other. Symbiosis may be obligate or facultative. In obligate symbiosis, one or both species depends on the other for survival.
Mutualism is an interaction between two or more species, where species derive a mutual benefit, for example an increased carrying capacity. Similar interactions within a species are known as co-operation. Mutualism may be classified in terms of the closeness of association, the closest being symbiosis, which is often confused with mutualism.
The first group proposed that animal domestication proceeded along a continuum of stages from anthropophily, commensalism, control in the wild, control of captive animals, extensive breeding, intensive breeding, and finally to pets in a slow, gradually intensifying relationship between humans and animals.

This term is used for organisms that "directly or indirectly modulate availability of resources (other than themselves) to other species, by causing physical state changes in biotic or abiotic materials". Beavers are an example of such engineers. Other examples include earthworms, trees, coral reefs, and planktonic organisms.
Commensalism describes a relationship between two living organisms where one benefits and the other is not significantly harmed or helped. It is derived from the English word commensal, used of human social interaction. It derives from a medieval Latin word meaning sharing food, formed from com-(with) and mensa (table). [38] [39]
There are three types of elephants: the African forest elephant, the Asian elephant, and the African savanna (or bush) elephant. Elephants in the African savanna are larger than those in the ...
It is unusual for interspecies communication to be observed in an older animal taking care of a younger animal of a different species. For example, Owen and Mzee, the odd couple of an orphaned baby hippopotamus and a 130-year-old Aldabran tortoise, display this relationship rarely seen in the animal world. Dr.
