Sex and flagellation.
Hurst L, Grafen A. Hurst L, et al. Trends Ecol Evol. 1990 Dec;5(12):419-22. doi: 10.1016/0169-5347(90)90029-D. Trends Ecol Evol. 1990. PMID: 21232406
It lives a Jekyll and Hyde existence, changing from the basal body, which seeds the production of cilia and flagellae, into the centriole, in which guise it is of uncertain function. ...

INTRASPECIFIC VARIATION IN ANT SEX RATIOS AND THE TRIVERS-HARE HYPOTHESIS.
Boomsma JJ, Grafen A. Boomsma JJ, et al. Evolution. 1990 Jul;44(4):1026-1034. doi: 10.1111/j.1558-5646.1990.tb03823.x. Evolution. 1990. PMID: 28569035
., colonies whose workers have a relatedness asymmetry below the population average should specialize in males, whereas colonies whose workers have a higher than average relatedness asymmetry should specialize in making females. ...

A centrosomal theory of the short term evolutionary maintenance of sexual reproduction.
Grafen A. Grafen A. J Theor Biol. 1988 Mar 21;131(2):163-73. doi: 10.1016/s0022-5193(88)80233-9. J Theor Biol. 1988. PMID: 3404998
A new mode of inheritance is postulated in which a sexual offspring receives a contribution from each parent and selects the better to pass on to its own offspring. This could provide a simple advantage to sex over a sex whose magnitude is shown

A general model of biological signals, from cues to handicaps.

Capturing the superorganism: a formal theory of group adaptation.
Gardner A, Grafen A. Gardner A, et al. J Evol Biol. 2009 Apr;22(4):659-71. doi: 10.1111/j.1420-9101.2008.01681.x. Epub 2009 Jan 20. J Evol Biol. 2009. PMID: 19210588
However, in recent years there has been a revival of interest in the possibility for group adaptations and superorganisms. Here, we provide the first formal theory of group adaptation. In particular: (1) we clarify the distinction between group selection and group adaptati …

An inclusive fitness analysis of altruism on a cyclical network.
Grafen A. Grafen A. J Evol Biol. 2007 Nov;20(6):2278-83. doi: 10.1111/j.1420-9101.2007.01413.x. J Evol Biol. 2007. PMID: 17956390
A recent model studies the evolution of cooperation on a network, and concludes with a result connecting the benefits and costs of interactions and the number of neighbours. ...The relatedness is a quadratic function of position in a cycle of si

Developments of the Price equation and natural selection under uncertainty.
Grafen A. Grafen A. Proc Biol Sci. 2000 Jun 22;267(1449):1223-7. doi: 10.1098/rspb.2000.1131. Proc Biol Sci. 2000. PMID: 10902688 Free PMC article.
However, the bulk of empirical research on adaptation and a great deal of theoretical work continue to employ these approaches. Here, a new theoretical development arising from the Price equation provides a formal justification in very general circumstances f …

The paper provides an explicit justification for the principle that a uniform taxon should contribute only one datapoint in comparative analyses with discrete variables. ...The consequence is that a uniform taxon cannot safely be counted as more than one datapoint. …
