Bringing Animal Behavior Home: Dogs As Members Of Human Packs

Wolves, the wild ancestors of domestic dogs, live in packs led by an adult male and female most of the pack members are the offspring of that pair. Much has been made about how a dog in a human household views itself as a pack member. Because early studies on wolves emphasized dominance relationships within packs, it seemed reasonable to interpret a dogs responses to the humans within its social group as a reflection of its dominance status in the group.

To a certain extent, the idea that dogs act like members of a human pack is true dogs can be very territorial in protecting a house and the members of the household. Dogs respond to leadership within a human household and are more likely to follow direction from an older, deep-voiced male human than from a female or from younger group members. Unfortunately, many humans interpret this to mean that they should somehow establish their dominance over household dogs, and do so by physical means, such as hitting, kicking, and forced roll-overs, so-called alpha rolls. These approaches may have disastrous consequences.

Development Of Modern Biology

Before the 18th century, the belief that different species could emerge from another species over the generations, inanimate objects or decaying life forms was widespread. Members of society also believed that plant species could be changed from changing climate. Only after the Swedish botanist Carl Linnaeus proposed the idea of species fixism it became widely accepted by society and other scientists. This enabled the scientific study of species change and the development of evolutionary theory, anchored by species specificity and hierarchical classifications.

What Did Hierarchy Originally Mean

The earliest meaning of hierarchy in English has to do with the ranks of different types of angels in the celestial order. The idea of categorizing groups according to rank readily transferred to the organization of priestly or other governmental rule. The word hierarchy is, in fact, related to a number of governmental words in English, such as monarchy, anarchy, and oligarchy, although it itself is now very rarely used in relation to government.

The word comes from the Greek hierarchs, which was formed by combining the words hieros, meaning supernatural, holy, and archos, meaning. ruler. Hierarchy has continued to spread its meaning beyond matters ecclesiastical and governmental, and today is commonly found used in reference to any one of a number of different forms of graded classification.

Essentials Of An Organizational Hierarchy

We are observing a large percentage of complex biological hierarchy in the nature that displays the hierarchical structure. If we count on theories, then we can anticipate the complex systems to be hierarchies which get evolved from the simple level or the lower levels. The basic foundation of the System hierarchy was done in the 1950s, which analyzed the field structure from 1980s calling it the hierarchical ecology.

Thermodynamics summarize the theoretical foundations. When you model the biological system as the physical system, in the simplest concept, it becomes a thermodynamic system. This system demonstrates theself organizedbehavior. The relations between the dissipative structures among its subset or sets can be considered as a hierarchy.

Levels Skepticism And Deflationary Accounts

Despite the familiarity of scientists and philosophers with the levelsconcept, calls for its dismissal or de-emphasis in the scientificlexicon are increasingly common . For one thing,nature may simply be too messy to fit any layer-cake style picture.Consider as an illustration the putative level oforganisms. Blue whales and yeast cells are both clearlyorganisms and thus should nominally be located at this level, but eachcomprises radically different kinds of entities with radicallydifferent properties . This may still bepalatable, but when we consider the next lower level, namely the oneindicated by the components of these organisms, the picture of levelsas neat horizontal layers breaks down completely. The components ofblue whales include things such as organs, tissues and cells, whereasyeast cells are composed of things like the cell membrane, nucleus andmitochondria . Furthermore, the whaleis in part composed of various symbionts, including gut bacteria. Suchsymbionts are at the same time components of the whale and organismsin themselves. Thus, the components of different kinds organisms donot form any homogeneous level.

More generally, Potochnik and McGill argue thatlevels imposes a radically false, rigid uniformity ontonature:

Levels In Biological Theory

Besides the more philosophical debates discussed above, levels oforganization also play an important conceptual role in biologicalresearch and theory. Interestingly, this growing body of literature onlevels in evolutionary biology is almost entirely disconnected fromthe debates on levels in philosophy of science discussed above.

A prominent example is the issue of levels of selection. In thisdebate, the hierarchical organization of nature into levels is animportant background assumption, as the aim is to find out at whichlevel of the biological hierarchy natural selection is taking place. Although Darwins originalaccount was focused on evolution at the level of organisms, arguablythe conditions for natural selection can be formulated abstractlywithout referring to any specific kinds of entities, which allows fornatural selection to operate at any level where the conditions aresatisfied . Since the 1970s, the debateon levels of selection has kept on growing and extending to differentareas, though no precise consensus has been reached. Positions rangefrom the gene-centered view, where natural selection is taken tooperate almost exclusively at the level of genes , to the pluralistic multilevel selection theory, whichallows for natural selection to operate on any level of the biologicalhierarchy where we find the right kind of units .

Dominance Hierarchies In Social Groups

The best known dominance hierarchies, such as those in flocks of domestic hens, are linear, meaning that there is one individual that dominates the others, there is a second individual that dominates all others except A, there is a third individual that dominates all the others except A and B, and so on, so that if they were to be ordered by their ranks, relative to others in the group, they would form a straight line. A linear hierarchy is one in which each animal is dominated by higher-ranking group members and, in turn, dominates lower-ranking members. Other types of dominance hierarchies are known in various primates, in herds of ungulates, and in cockroaches.23 Whether the group is composed of related or unrelated animals, dominance hierarchies can structure social interactions in groups.

• What Is Cephalization in Zoology?

Ecological hierarchy theory describes the arrangement of biological organisms in relation to one another. At the simplest level of the hierarchy are individual organisms. At the individual level, interactions with other organisms are not considered. Moving up the hierarchy, ecologists have found more complex ways to describe the relationships between organisms. These culminate in the biosphere, which describes the totality of all living things on planet Earth.

Do We Really Need Hierarchy

In fact a study conducted by Stanford’s Graduate School of Business found that sometimes a hierarchy is preferred to a completely equal structure. This is because it makes it easier for employees to understand relationships within an organization as well as where they stand among their peers and colleagues.

The Historical Origins Of The Concept

When levels of organization are understood as belonging to the broadercategory of hierarchical depictions of nature, their history can betraced all the way back to the early days of western science andphilosophy. Aristotle suggested that living things could be arrangedin a graded scale, starting from plants at the bottom and ending withhumans at the top. This idea was further developed in Neoplatonism,and in Medieval times, it transformed into the idea of theGreat Chain of Being . This ScalaNaturae conveyed a hierarchical conception of the world asmodeled after the perfection of the Deity: at the top, there is God,and at lower rungs, angels, humans, animals, plants, and so on. Afterthe scientific revolution, more scientific classifications of naturestarted to appear, the most famous ones being Linneaustaxonomical system and Auguste Comtes hierarchy of the sciences.

The roots of the contemporary notion of levels of organization and theassociated hierarchical thinking are best linked to the efforts oforganicist biologists of the early-mid 20th century . Particularly important to the introduction anddevelopment of the levels concept were Joseph Woodger ,Ludwig von Bertalanffy , and Joseph Needham . These individuals were in turn influenced by Alfred NorthWhiteheads philosophy .

The levels concept proved to be a linchpin of these main tenets.Joseph Woodger, combining these features, thus expresses the basicthinking behind levels of organization:
