A recent piece in The Atlantic argues fathers-to-be should abstain from alcohol when trying to conceive. The science that underpins this recommendation has some issues.

Harry Harlow
Harry Frederick Harlow was an American psychologist best known for his maternal-separation, dependency needs, and social isolation experiments on rhesus monkeys, which manifested the importance of caregiving and companionship to social and cognitive development. He conducted most of his research at the University of Wisconsin–Madison, where humanistic psychologist Abraham Maslow worked with him for a short period of time.

One mother for two species via obligate cross-species cloning in ants
Living organisms are assumed to produce same-species offspring1,2. Here, we report a shift from this norm in Messor ibericus, an ant that lays individuals from two distinct species. In this life cycle, females must clone males of another species because they require their sperm to produce the worker caste. As a result, males from the same mother exhibit distinct genomes and morphologies, as they belong to species that diverged over 5 million years ago. The evolutionary history of this system appears as sexual parasitism3 that evolved into a natural case of cross-species cloning4,5, resulting in the maintenance of a male-only lineage cloned through distinct species’ ova. We term females exhibiting this reproductive mode as xenoparous, meaning they give birth to other species as part of their life cycle.
Advancing the Understanding of Phenotypic Mimicry in Men’s Conspicuous Consumption
Two studies advance the understanding of phenotypic mimicry in consumer products. Product features mimicking more prominent male secondary sexual characteristics are associated with men’s behavioral strategies which are higher in mating effort and lower in paternal investment in offspring, in parallel with reproductive strategies across species and within the human population. The first study demonstrated a continuous relationship between the sizes of luxury brand logos and perceptions of the owners’ life histories. Two partial replications reproduced Study 1 results. Study 2 demonstrated that a manipulation of coloration, another fundamental dimension of variation in secondary sex characteristics, generates a similar pattern of results. In both studies, men owning shirts with more prominent sensory characteristics were believed to use authority and intimidation as strategies for advancing social status, whereas men owning shirts with less showy characteristics were believed to demonstrate useful abilities and foster cooperative alliances. Participants also recognized the strategic use of luxury display properties across social contexts.
“I am Not the Grace of Doe” – Radiant Obscurities
There is a beautiful and romanticized image of the doe. The doe is graceful, elegant, and delicate. She is shy and unattainable, disappearing softly at the slightest sound. Her eyes have become a cliche for the vulnerable, docile feminine, and a glimpse of her, staring back at you for a profound moment before she flies, is precious and moving.I am not this doe.In fact, in a way I hate this doe. No doe is really this doe. Let me tell you a few things about cervids, the whitetail doe in particular. Cervids are olfactory animals. That means they learn things about other deer with their sense of smell. What that means is that the smelliest things about deer are pretty crucial to the way deer live. As with many animals, urine plays a large part in communication – males will urinate in pools and wallow in them to advertise; they will also urinate on their feet to leave their scent with their hoofprints. Females advertise their eligibility to mate by urinating, also.It means that does will ingest the excrement of their young in order to prevent fawns from having a scent that would give away their position to predators.Does aren’t always gentle or vulnerable.In winter, does that are healthier and more able to sense danger will actively prevent other does and fawns from having access to food. Even if a high-ranking doe no longer needs to eat, she will fend off others from the food area and not allow them access, even if they are starving.Nor do deer always flee in the face of danger – several accounts chronicle deer attacking dogs and humans when threatened, in some cases quite brutally. Not many animals hold up closely to their romanticized stereotypes when their survival is put into question, but the desperate deer is the exact opposite of its gentle popular image, its adorable hoofs formidable and unexpected weapons.Besides that, deer do kill, sometimes to eat. A number of articles bring to light the fact that deer do eat carrion, and there is record of deer killing and eating grounded birds.For me, though, there’s more that negates the image of the wholly graceful doe than just wildlife facts. Because the grace of deer, the elegance, is not what makes me deer. As far as the romantic stereotype goes, I do usually feel more inclined to flight, and can be standoffish as a mode of self-preservation. I feel vulnerable in the way that I recognize deer are very, very “killable” – living in Vermont, I saw a great deal of dead deer and the mortality of the whitetail in a hunting community that supports a healthy coyote population was impossible to ignore. I do not feel graceful; usually I feel colossally awkward, and something about deer speaks of that awkwardness to me. Being spooked about nothing, the awkward indignation of being disturbed, the skittering flight are all deer. These things are aspects of the romantic stereotype, but I do not perceive them in a romantic way. I do not think being deer makes me mysterious, desirable, or delicate. Since I’ve become able to consciously analyze my animality, I have found it extremely important to define myself by the more negative or humble aspects of an animal as well as the positive and proud ones. I have difficulty understanding people who speak of their animality primarily in terms of the powerful, beautiful, majestic, or strong. Yes, there are things about deer that I think are lovely and ideal and that I relate to very much. I love the flick of their ears, the clarity of their gaze, the small cloven hoof poised not quite touching the ground, the flag of the tail, the sudden and fleeting bounding away. These are things that I can feel. But I can also feel the awkward stretch of the neck for browse, the indignation of being encroached upon, the need to hide, to flee, to fear. I can feel the undignified sound of the grunt and wheeze, the frozen discomfort of surprise and being caught in headlights, so to speak, and the hurried skitter away. Even the olfactory things that we consider unpleasant or gross in our culture make some sense to me – conveniently, as a human, I do not need to use urine to communicate sexual availability, but I rarely feel the need to rid myself of sexual smells when I notice them. I can’t deny the beauty and seriousness of feeling deer, or of following a deer path through the woods. I can’t ignore the bark and smell, the moss and magic, but I also can’t ignore that these paths are liberally punctuated with droppings. And this, for me, is an adequate metaphor for my experience of being doe: I can acknowledge the beautiful and wonderful, but must take into account the awkward and uncomfortable as well. I would not be deer if I could not accept both the loveliness and the unpleasantness of the doe.
Rethinking Norm Psychology
Norms permeate human life. Most of people’s activities can be characterized by rules about what is appropriate, allowed, required, or forbidden—rules that are crucial in making people hyper-cooperative animals. In this article, I examine the current cognitive-evolutionary account of “norm psychology” and propose an alternative that is better supported by evidence and better placed to promote interdisciplinary dialogue. The incumbent theory focuses on rules and claims that humans genetically inherit cognitive and motivational mechanisms specialized for processing these rules. The cultural-evolutionary alternative defines normativity in relation to behavior—compliance, enforcement, and commentary—and suggests that it depends on implicit and explicit processes. The implicit processes are genetically inherited and domain-general; rather than being specialized for normativity, they do many jobs in many species. The explicit processes are culturally inherited and domain-specific; they are constructed from mentalizing and reasoning by social interaction in childhood. The cultural-evolutionary, or “cognitive gadget,” perspective suggests that people alive today—parents, educators, elders, politicians, lawyers—have more responsibility for sustaining normativity than the nativist view implies. People’s actions not only shape and transmit the rules, but they also create in each new generation mental processes that can grasp the rules and put them into action.
