A solitary Deinonychus could not kill an adult tenontosaur, suggesting that pack hunting is possible. [4] A 2007 study by Roach and Brinkman has called into question the cooperative pack hunting behavior of Deinonychus, based on what is known of modern carnivore hunting and the taphonomy of tenontosaur sites.
Sociobiology investigates social behaviors such as mating patterns, territorial fights, pack hunting, and the hive society of social insects. It argues that just as selection pressure led to animals evolving useful ways of interacting with the natural environment , so also it led to the genetic evolution of advantageous social behavior.
Suzanne Batra introduced the term "eusocial" [1] after studying nesting in Halictid bees including Halictus latisignatus, [2] pictured.. The term "eusocial" was introduced in 1966 by Suzanne Batra, who used it to describe nesting behavior in Halictid bees, on a scale of subsocial/solitary, colonial/communal, semisocial, and eusocial, where a colony is started by a single individual.
The individuals giving up their own reproductive success form a sterile caste of workers within the group. All species that practice reproductive altruism produce one or more queens, the only breeding females, who are larger than the rest. The remainder of the society is composed of a few breeding males, sterile male and female workers, and the ...
The co-operative behaviour of social insects like the honey bee can be explained by kin selection.. Kin selection is a process whereby natural selection favours a trait due to its positive effects on the reproductive success of an organism's relatives, even when at a cost to the organism's own survival and reproduction.

Primate sociality is an area of primatology that aims to study the interactions between three main elements of a primate social network: the social organisation, the social structure and the mating system. The intersection of these three structures describe the socially complex behaviours and relationships occurring among adult males and ...
Many examples of genetic factors of social behavior have been derived from a bottom-up method of altering a gene and observing the change it produces in an organism. Sociogenomics is an integrated field that accounts for the complete cellular genetic complement of an organism from a top-down approach, accounting for all biotic influences that ...
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.
