The significant theoretical objections that have been raised against memetics have not received adequate defense, even though there is ongoing empirical research in this field. In this paper I identify the key objections to memetics as a viable explanatory tool in studies of cultural evolution. I attempt to defuse these objections by arguing that they fail to show the absence of replication, high-fidelity copying, or lineages in the cultural domain. I further respond to meme critics by arguing that, despite competing explanations of cultural evolution, memetics has unique explanatory power. This is largely founded upon the increasing likelihood of formulating a workable fitness measure for memes, a memetic index. I conclude that memes must be integrated with psychological bias and population-dynamic approaches to cultural evolution.

One of the key learning objectives in any health professional course is to develop ethical and judicious practice. Therefore, it is important to address how medical and pharmacy students respond to, and deal with, ethical dilemmas in their clinical environments. In this paper, we examined how students communicated their resolution of ethical dilemmas and the alignment between these communications and the four principles developed by Beauchamp and Childress. Three hundred and fifty-seven pharmacy and medical students (overall response rate=63%) completed a questionnaire containing four clinical case scenarios with an ethical dilemma. Data were analysed using multiple methods. The findings revealed that 73% of the qualitative responses could be exclusively coded to one of the ‘four principles’ determined by the Beauchamp and Childress' framework. Additionally, 14% of responses overlapped between the four principles (multiple codes) and 13% of responses could not be coded using the framework. The subsequent subgroup analysis revealed different response patterns depending on the case being reviewed. The findings showed that when students are faced with challenging ethical dilemmas their responses can be aligned with the Beauchamp and Childress framework, although more contentious dilemmas involving issues of law are less easily categorised. The differences between year and discipline groups show students are developing ethical frames of reference that may be linked with their teaching environments and their levels of understanding. Analysis of these response patterns provides insight into the way students will likely respond in ‘real’ settings and this information may help educators prepare students for these clinical ethical dilemmas.

The Oxford Handbook of Philosophy of Biology covers a broad range of topics in this field. It is not just a textbook focusing on evolutionary theory but encompasses ethics, social science and behaviour too. This essay outlines the scope of the work, discusses some points on methodology in the philosophy of biology, and then moves on to a more detailed analysis of cultural evolution and the applicability of a philosophy of biology toolkit to the social sciences. It is noted that concepts like the species concept may generalise to other domains whilst failing to account for the nature of all species. Finally, the author notes the omission of any discussion of information in biology

Darwin’s Conjecture is a bold attempt to bring evolutionary explanation to the social sciences, particularly economics. The book outlines the history of Darwinian explanation in social science then puts forward a generalized replicator account of social evolution by natural selection. The authors identify habits and routines as examples of the generative replicators necessary in order that social evolution is Darwinian. This reviewer notes that the replicator approach limits the generality of this account and suggests that habits and routines might better be seen as members of a Darwinian population in the tradition of Godfrey-Smith’s (2009) generalized account of natural selection instead. Furthermore, the existence of levels of social evolution will constrain what evolution can occur low in the hierarchy.
