With reference to consistent language, the use of the terms "conspecific" and "partner" in the same sentence conveyed ambiguity.
(15) Altruism may arise from individual selection. Sanchez A and Cuesta JA. 2005. Journal of Theoretical Biology, volume 235, pages 233-240. Page 234: only offer the minimum amount that you, yourself, would accept.
With reference to "non-kin", is one's partner "non-kin"? Is one's partner's extended family a large group of "non-kin"?
(16) Altruism and social cheating in the social amoeba Dictyostelium Discoideum. Strassmann JE, Zhu Y and Queller DC. 2000. Nature, volume 408, pages 965-967. Comment. Cooperation can be dangerous. Kessin R. 2000. Nature, volume 408, pages 917-919.
With reference to the theory of social cheating, the disproof of this would require supposedly identical cells to be studied for actual differences, for example, in gene expression, which would predict differentiation into a stalk or a spore.
(17) The ritualization of agonistic behaviour as a determinant of variation along the neuroticism/stability dimension of personality. Price JS. 1969. Proceedings of the Royal Society of Medicine, volume 62, pages 1107-1110.
With reference to throwaway remarks: "But it is worth remembering that human neurosis is largely a subjective affair, and the behavioural accompaniments are more often confined to limitation of certain types of behaviour than to any positive deviation." Anxiety?
With reference to how the content of an article should reflect its title, the dimensions of personality described in the title are not discussed in any detail in the article, the last sentence of which appears to acknowledge this. For example, how does the ritualization of agonistic bebhaviour vary, if at all, along other dimensions of personality, such as extraversion/introversion?
With reference to inhibition, the advantage to the child who "yields" and does not show his or her anger is the avoidance of abandonment with exposure to predators.
(18) The logic of animal conflict. Maynard Smith J and Price GR. 1973. Nature, volume 246, pages 15-18.
With reference to quotation marks, these are used so often in the article as to convey contrivance, and to provoke a question about whether the authors and the editor asked themselves what their use of quotation marks might mean.
With reference to the individual benefits of fights that do not cause serious injury between animals, these are obvious without game theory and computer simulation, and include practice for real fights, and winding down.
