Evidence for animal culture is often based on studies of feeding behaviors, [8] vocalizations, [4] predator avoidance, [9] mate selection, [10] and migratory routes. [11] An important area of study for animal culture is vocal learning, the ability to make new sounds through imitation. [4] Most species cannot learn to imitate sounds.
The manner in which hormones alter these receptors is an important behavioral regulator. For example, gonads affect OTRs in different rodents . In female rats, gonadal estrogen increases the level of OTR binding and, when the ovarian cycle maximizes the amount of estrogen in the bloodstream, causes OTRs to appear in ventrolateral regions of the ...
Waddington called the effect he had seen "genetic assimilation". His explanation was that it was caused by a process he called "canalization".He compared embryonic development to a ball rolling down a slope in what he called an epigenetic landscape, where each point on the landscape is a possible state of the organism (involving many variables).
Synchronous behavior is also threatened when animals in a mixed-sex herd have differing nutritional or physical necessities. This causes group instability which often splits the herd up into two separate groups; generally all male and all female, to recreate the mimetic behavior in a smaller, same-sex group that has more similar needs to the individual.

Heralded as the world's largest rodents, the South American rainforest natives can actually weigh as much as a full grown man.. But despite the fact that they apparently like to eat their own dung ...
Collective animal behaviour is a form of social behavior involving the coordinated behavior of large groups of similar animals as well as emergent properties of these groups. This can include the costs and benefits of group membership, the transfer of information, decision-making process, locomotion and synchronization of the group.
Domestication has been defined as "a sustained multi-generational, mutualistic relationship in which one organism assumes a significant degree of influence over the reproduction and care of another organism in order to secure a more predictable supply of a resource of interest, and through which the partner organism gains advantage over individuals that remain outside this relationship ...
