Our paper on the women's hunting debate has finally been published in @EvolHumBehav Our point is simple: women sometimes hunt in foraging societies, but gendered divisions of labor still exist.

A new paper synthesizes existing reports on the context of women’s hunting in foragers. The big takeaway: women hunt in roughly 80% of foragers. We need to view this estimate with skepticism, and here’s why. A thread (1/12)

In conclusion, no recent paper has overturned consensus views of gendered divisions of labor in modern hunter-gatherers. In foragers, men and women generally do different things, and the flexibility of this division has been recognized for decades. 13/13

In foraging societies, men not only hunt; they also gather. As @sheinalew points out, this is more understudied than women's hunting. Here's an example from the Batek of Malaysia

We highlight that the fundamental issue with the paper is that women’s hunting is not a binary phenomenon. Treating it as such obscures the nuance that makes women’s hunting an interesting example of the flexibility of gendered divisions of labor. 8/13

There is an over-representation of studies with evidence of women’s hunting. Many relevant studies with hunting data were excluded, few of which showed evidence of female hunting. Thus, the 79% estimate is likely inflated. 5/13

The paper claims to oppose “the traditional paradigm that women exclusively gather and men exclusively hunt” But no one thinks this. It does not do justice to the intellectual history of forager studies, nor to more recent nuanced work on divisions of labour. (7/12)

My takeaway: It is by no means clear when gendered DOL’s emerged in human evolution. But hypotheses that put the timing before agriculture are not Paleofantasies. They are hypotheses subject to testing and each version has its own strengths and weaknesses.

From the paper: “Fathers only provide 5.5%–5.7% of each of the three forms of care to children under 1.5 years old. Among 1.5- to 4-year-olds, fathers provide 3.5% of close care and holding, and 8.4% of physical contact.” In other words, childcare is mostly done by women.

That being said, it’s good to see the attempt. Reports of women’s hunting have been around for decades. Many cases must go unreported. It may be easy to overlook, and the majority of old-school ethnographers were male. I suspect 80% is too high, and 13% is too low. (6/12)

No arguments are presented to support this idea, even though it could be testable. The authors don’t grapple with clear counter-examples, such as Australian Aboriginals and their distinct pre-contact situation. Even early post-contact reports consistently mention gendered DOL’s.

As an aside, we should be cautious in drawing conclusions about behavior from skeletal robusticity. Too much going on, and too much missing from archaeological samples. From: Wallace, I.J., Demes, B. and Judex, S., 2017.

The other (Holt and Formicola 2008) doesn’t seem to make any strong claim about DOL’s. They just note female bone robusticity was higher in the Upper Paleolithic compared to recent foragers.

These inferences are based on life history and behavioural ecology. We can surmise that women hunted in the past without it needing to be true that women hunt in the majority of modern foragers. Otherwise we are manufacturing our own tyranny of the ethnographic record. (11/12)

One more thing: widespread hunting by women is interpreted as evidence of hunting specialization. This is precisely the opposite of explanations when archaeologists infer women’s hunting in ancient contexts. Less need to specialize = more involvement by women.

The authors write: “Foragers are not living fossils.” No anthros think foragers are living fossils. We study foragers using behavioral ecology to understand how patterns of behavior emerge in response to ecological and social pressures.

So in a way this replaces women's labor, and women become involved in rattan collection. This is a collaborative gathering activity between the genders. Men climb the trees and do the risky work; women help to locate, coordinate, help to carry, and process.

Overall, women’s hunting occurs in 13% (50/391) of foragers. Hunting almost certainly occurs in the other 328 societies they didn’t examine. Is it likely that it occurs in 80% of the rest? That's hard to imagine. At present, the data don't support the 80% estimate. (5/12)

Why do we think that women’s hunting was probably more common in the past? 1. Game was larger and more abundant than in recent times. This would have changed the riskiness of hunting (i.e. probability of failure). If hunting is less risky, women are more likely to hunt. (8/12)

What do we see among modern foragers? From Gurven and Hill (2009): “Men and women hunt in 13 societies, and in none do women alone hunt, whereas women are the main gatherers in two-thirds of these societies.” This corresponds to <10 % of societies in which women hunt. (3/12)

A resource like rattan exhibits a set of properties that mixes the attributes of hunting and gathering. Sessile resource, but very high return rate, with elements of comparative advantage in terms of the need for strength and sensitivity to risk (climbing tall trees).
