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 ...
Relatedness does still play a part, as monogamy (queens mating singly) is the ancestral state for all eusocial species so far investigated. [73] If kin selection is an important force driving the evolution of eusociality, monogamy should be the ancestral state, because it maximizes the relatedness of colony members.
Cooperation among ants is vital, because a solitary ant has an improbable chance of long-term survival and reproduction. However, as part of a group, colonies can thrive for decades. As a consequence, ants are one of the most successful families of species on the planet, accounting for a biomass that rivals that of the human species. [1] [2]
An animal that exhibits a high degree of sociality is called a social animal. The highest degree of sociality recognized by sociobiologists is eusociality . A eusocial taxon is one that exhibits overlapping adult generations , reproductive division of labor , cooperative care of young, and—in the most refined cases—a biological caste system .
The 19th-century thinker Herbert Spencer coined the term super-organic to focus on social organization (the first chapter of his Principles of Sociology is entitled "Super-organic Evolution" [14]), though this was apparently a distinction between the organic and the social, not an identity: Spencer explored the holistic nature of society as a social organism while distinguishing the ways in ...
Human exceptionalism is usually combined with the claim that human well-being matters more than the well-being of other species. This line of thought can be used to draw various ethical conclusions. One is the claim that humans have the right to rule the planet and impose their will on other species.
A group could only constitute a race if breeding with a different degeneration resulted in "intermediate offspring." [14] Although Kant advocated for a theory of shared human origin, he also contended that there was an innate hierarchy between existing races. In 1788, Kant wrote "Über den Gebrauch teleologischer Prinzipien". [5]
The Drunkard's Progress: by Nathaniel Currier 1846, warns that moderate drinking leads, step-by-step, to total disaster.. Moralism is a philosophy that arose in the 19th century that concerns itself with imbuing society with a certain set of morals, usually traditional behaviour, but also "justice, freedom, and equality".
