In organisms that breed multiple times and live in places where food availability and mortality change significantly on the basis of season, it is predicted that capital breeding will be more prevalent, as the time when the organism is not breeding but when conditions are still favourable will be dedicated to rebuilding stores, therefore allowing them to achieve higher rates of reproduction.
E.O. Wilson applied the term of ″sociobiology″ as an attempt to explain social behavior of insect and thus explored the evolutionary mechanism of other animals including human such as the social behavior, altruism. [13] He argued that human altruistic behavior, as one of the human nature characteristics, is the result of the genetic ...
For example, in America in 2012 there were some 78 million dogs, 86 million cats, and 3.5 million rabbits. [55] [56] [57] There is a tension between the role of animals as companions to humans, and their existence as individuals with rights of their own. [58] Many animals are hunted for sport. [59]

Zoology – study of animals.Zoology, or "animal biology", is the branch of biology that relates to the animal kingdom, including the identification, structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems.
For example, in America in 2012 there were some 78 million dogs, 86 million cats, and 3.5 million rabbits. [44] [45] [46] Anthropomorphism, the attribution of human traits to non-human animals, is an important aspect of the way that humans relate to other animals such as pets.

These specific systems are widely studied in human anatomy and are also present in many other animals. Respiratory system: the organs used for breathing, the pharynx, larynx, bronchi, lungs and diaphragm. Digestive system: digestion and processing food with salivary glands, oesophagus, stomach, liver, gallbladder, pancreas, intestines, rectum ...
