There is gold in "unpublished" dissertations

According to #evopsych, it's not surprising that male tourists pay for sex with locals. What is surprising, as April Gorry found, is that women do the same. Is #evopsych wrong about women's mating psychology? In some ways, yes:

A 🧵
2. White women tourists visiting the Caribbean and other warm-weather locales are stereotyped as sex-starved nymphomaniacs lusting after sexually potent dark-skinned men. Where did this myth come from?
3. Western tourist women often do enter into sexual relationships with local men in Belize, where Gorry did her fieldwork, and many other resort locations:
4. The men that tourist women choose seem to lack all the qualities, such as financial resources and status, that #evopsych claims they should have. In an apparent reversal of sex roles, tourist women often provide their sexual partners with substantial financial resources:
5. What's going on? Women tourists unfamiliar w/ the local culture don't recognize the men's low status but do notice universal aspects of their mate quality. First, men display cues of competency & mastery of the physical & social environments, which indicate resource potential:
6. Second, the men exhibit powerful cues of investment and devotion:
7. Gorry's female informants describe intense emotional experiences:
8. But in many cases it's a hustle. Local men at the bottom of the economic and ethnic hierarchy learn to feign indicators of romantic love in order to obtain sexual and financial benefits from tourist women:
9. The motivations of the men, however, are not quite so simple:
10. Gorry concludes her dissertation with an analysis of #RomanceNovels. The male heroes are universally portrayed as masters of their physical and social environments...
11. ...and the heroes are obsessed with the heroine.

In ancestral environments, competence and devotion would have been reliable indicators of male mate value, and are probably stronger cues than the evolutionarily novel financial resources often emphasized in #evopsych:

13. Her 1994 MA thesis on #femalecompetition looks interesting too (not sure if it's available anywhere):

Postscript. The informants for the romance tourist study:

1. After I posted my critical review of @Anthrofuentes Sex is a Spectrum, a colleague pointed out that his figure of adult heights by sex (bottom panel👇) can't be right: there aren't that many US adults shorter than 4' or taller than 7'

Turns out Fuentes' data are made up 🧵 Top panel: My plot of US adult female and male height distributions, which are much narrower, and overlap less than in the figure from Fuentes, which is in the bottom panel.
2. First, I plotted the height distributions using nationally representative data from NHANES and percentiles from the CDC (top panel 👆). I just used default settings in the density function for the distributions, but they're probably OK. They're narrower and show less overlap.
3. So where did Fuentes' figure come from? Fuentes cites an old blogpost by Fausto-Sterling as the source for his figure, but she doesn't provide her source for the figure (no mention of the CDC): huffpost.com/entry/the-scie…

1. The evolution of [proto] music. My arguments against the social bonding hypothesis and in favor of the signaling hypothesis

The Explicandum: The evolution in the human lineage of vocalizations that are:

* Loud
* Synchronized
* Variable

🧵
2. The social bonding hypothesis

* Primate group cohesion putatively requires grooming
* Grooming time putatively increases w/ group size
* Large human groups required more efficient "bonding" mechanisms
* Language, music, & dance evolved to replace grooming as the mechanisms
3. Here are Dunbar's original data. After accounting for terrestrial primate species, which have larger group sizes and also groom more than arboreal species, there is little evidence that grooming time increases with group size:

1. Early in development, the presence of a Y chromosome triggers development of the testes, which then secrete testosterone, which then shunts fetal development to a male phenotype.

But I was curious: beyond gonads & hormones, do XX and XY contribute to sex differences? 🧵 Diagram of inequalities in sex chromosomes: Sry/No Sry, Y vs no Y, Xist, 1 vs 2 X, epigenetics of X, Y chromatin
2. IOW, sex diffs in phenotypes are due to sex diffs in hormones acting on cellular hormone receptors, altering expression of (mostly) autosomal genes in numerous tissues.

But could some sex diffs be due to, eg, Y chr genes expressed outside the testes? onlinelibrary.wiley.com/doi/full/10.10…
3. To answer, it's important to know that X & Y evolved from an autosome pair that ceased to recombine starting >180 million years ago. The Y, which contained the sex determining gene SRY, began to lose genes. Today, X has about ~1000 genes & Y ~100. nature.com/articles/natur…

1. The Santa Barbara school of evolutionary psychology holds that a universal set of complex psychological adaptations evolved in Pleistocene Africa. In no particular order, here are few folks on here doing research in this tradition, highlighting one paper/thread each:🧵

3. @JaimieKrems investigates female friendships (and many other topics):

1. Does research by @CaraOcobock @Anthrofuentes & others, widely reported in SciAm & elsewhere, finally dispel hunter-gatherer myths that have persisted since the 60's?

In a preprint led by @vivek_vasi The Meanings&Dividends of Man the Hunter we respond🧵 osf.io/preprints/osf/…Scientific American cover article: Woman the Hunter: New science debunks the myth that men evolved to hunt and women to gather
2. In 1966, 75 hunter-gatherer specialists met at the University of Chicago for a conference titled Man the Hunter, organized by Richard Lee and Irv DeVore, who were graduate students of Berkeley primatologist Sherwood Washburn.
3. The motivations were to (1) present many new data on hunter-gatherers, and (2) clarify conceptual issues surrounding human evolution. The talks were published in a 1968 volume of the same name, one of the most influential & controversial in anthro: archive.org/details/ManThe…Cover: Man the Hunter. Richard B.

1. What's at risk by disrupting NIH? With only a bit of hyperbole: a mechanistic understanding of life itself, & therefore better treatments for cancer, dementias, autoimmune disorders, neurodegenerative diseases, birth defects, aging & more.

Notes on a revolution interrupted 🧵 Illustration of a cell depicting locations of various proteins
2. The cell is the fundamental unit of life. Every thought in your head, every memory, every sensation, every metabolic process in your gut, every defense against infection, every (forgive me) breath you take, every move you make, every word you say, is a cellular process.
3. Cancer and the other diseases noted above are dysfunctions of cellular processes and/or of cell-cell interactions.
