A new genetic study, published in the journal Neuron, calls into question the traditional belief that the “love hormone” oxytocin plays a crucial role in social attachments. The study found that prairie voles can form long-lasting bonds with their partners and care for their offspring without oxytocin receptor signaling, despite decades of research suggesting otherwise. Study finds that prairie voles without oxytocin receptors can bond with mates and young. The vital role of oxytocin—the “love hormone”—for social attachments is being called into question. More than forty years of pharmacological and behavioral research has pointed to oxytocin receptor signaling as an essential pathway for the development of social behaviors in prairie voles, humans, and other species, but a genetic study publishing in the journal Neuron on January 27 shows that voles can form enduring attachments with mates and provide parental care without oxytocin receptor signaling. Prairie voles are one of only a few monogamous mammalian species. After mating, they form lifelong partnerships known as “pair-bonds.” Pair-bonded voles share parental responsibilities, prefer the company of their partner over unknown members of the opposite sex, and actively reject potential new partners. Previous studies that used drugs to block oxytocin from binding to its receptor found that voles were unable to pair-bond when oxytocin signaling was blocked. This is a photograph of two prairie voles. Prairie voles are a type of rodent that is native to North America. They are known for their strong social bonds and cooperative breeding behaviors. Prairie voles are often used in scientific research, particularly in the study of genetics and social behavior, as their behavior is similar to that of other social mammals, including humans.  Credit: Nastacia Goodwin Neuroscientists Devanand Manoli of UCSF and Nirao Shah of Stanford University wanted to know whether pair-bonding was really controlled by oxytocin receptor signaling. To test this, they used CRISPR to generate prairie voles that lack functional oxytocin receptors. Then, they tested these mutant oxytocin-receptor-less voles to see whether they could form enduring partnerships with other voles. To their surprise, the mutant voles formed pair-bonds just as readily as normal voles. “We were all shocked that no matter how many different ways we tried to test this, the voles demonstrated a very robust social attachment with their sexual partner, as strong as their normal counterparts,” says Manoli. Next, the researchers wondered whether oxytocin receptor signaling is similarly dispensable for its other functions—parturition, parenting (which, in prairie voles, is a shared responsibility between the two parents), and milk release during lactation. “We found that mutant voles are not only able to give birth, but actually nurse,” says Shah. Both male and female mutants engaged in the usual parental behaviors of huddling, licking, and grooming, and were able to rear pups to weaning age. This is a photograph of a couple of prairie voles. They have unique genetic, physiological, and behavioral characteristics that make them a model organism to study the neural and molecular mechanisms underlying social behaviors. Credit: Nastacia Goodwin Species-Specific Differences in Oxytocin Dependence However, the mutant prairie voles did have limited milk release compared to normal voles. As a result, fewer of their pups survived to weaning age, and those that did survive were smaller compared to the pups of normal prairie voles. The fact that the voles could nurse at all is in contrast to equivalent studies in oxytocin receptor-deficient mice, who completely failed to lactate or nurse, and whose pups consequently died within a day or so of being born. The authors hypothesize that this species difference could be due to the inbred nature of laboratory mouse strains in contrast to the genetically heterogenous voles. “It could be that inbreeding in mice has selected for a large dependence on oxytocin signaling, or this may represent a species-specific role of oxytocin receptor signaling,” says Shah. When asked why their results differ from previously published studies that used drugs to block oxytocin receptor signaling, the authors point to the key difference between genetic and pharmacological studies: precision. “Drugs can be dirty,” says Manoli, “in the sense that they can bind to multiple receptors, and you don’t know which binding action is causing the effect. From a genetics perspective, we now know that the precision of deleting this one receptor, and subsequently eliminating its signaling pathways, does not interfere with these behaviors.” Oxytocin-Based Therapeutics “For at least the last ten years people have been hoping for the possibility of oxytocin as a powerful therapeutic for helping people with social cognitive impairments due to conditions ranging from autism to schizophrenia,” Manoli says. “This research shows that there likely isn’t a magic bullet for something as complex and nuanced as social behavior.” Another key difference is that, whereas most pharmacological studies suppress oxytocin receptor signaling in adult animals, this study switched it off when the voles were embryos. “We’ve made a mutation that starts from before birth,” says Shah. “It could be that there are compensatory or redundant pathways that kick-in in these mutant animals and mask the deficits in attachment, parental behaviors, and milk let-down.” Working with prairie voles presented an obstacle, but one worth overcoming. Because prairie voles are not commonly used in genetic studies like laboratory mice, the team needed to develop all of their molecular tools and protocols from scratch. Now that they have these vole-specific pipelines and tools, the authors are excited about the doorways this opens, both for them and for other researchers. “We’re very happy to be part of a community and to have this technology that we can share,” says Manoli. “Now we have this trove that we can start to mine. There are so many other questions that prairie voles could be interesting and useful for answering, both in terms of potential clinical implications for models of anxiety or attachment and also for basic comparative biology.” Reference: “Oxytocin receptor is not required for social attachment in prairie voles” by Kristen M.

Social skills provide golden-mantled ground squirrels with an advantage. Humans acknowledge that personality goes a long way, at least for our species. But scientists have been more hesitant to ascribe personality—defined as consistent behavior over time—to other animals. A study from the University of California, Davis is the first to document personality in golden-mantled ground squirrels, which are common across the western U.S. and parts of Canada. The study, published in the journal Animal Behaviour, found the squirrels show personality for four main traits: boldness, aggressiveness, activity level, and sociability. While the golden-mantled ground squirrel is under no conservation threat, the findings suggest that understanding how an animal’s personality influences use of space is important for wildlife conservation. ‘Individuals matter’ To see them chitter and skitter, stop and then scurry, the fact that ground squirrels have personalities may not seem surprising. But the scientific field of animal personality is relatively young, as is the recognition that there are ecological consequences of animal personality. For instance, bolder, more aggressive squirrels may find more food or defend a larger territory, but their risky behavior may also make them vulnerable to predation or accidents. Golden-mantled ground squirrels do indeed have personality, a UC Davis study confirms. Credit: Jaclyn Aliperti, UC Davis “This adds to the small but growing number of studies showing that individuals matter,” said lead author Jaclyn Aliperti, who conducted the study while earning her Ph.D. in ecology at UC Davis. “Accounting for personality in wildlife management may be especially important when predicting wildlife responses to new conditions, such as changes or destruction of habitat due to human activity.” Personality tests Scientists have been studying golden-mantled ground squirrels at the Rocky Mountain Biological Laboratory in Gothic, Colorado for decades. It was established as a long-term study site more than 30 years ago by Aliperti’s advisor, Dirk Van Vuren, a professor in the UC Davis Department of Wildlife, Fish and Conservation Biology. Aliperti drew from this powerful data set for her study, while also initiating a series of experiments there over the course of three summers to observe and quantify the squirrels’ personalities. She notes that while there are no Meyers-Briggs tests for animals, there are standardized approaches to quantifying animal personalities. She observed and recorded squirrel responses to four tests: Novel environment: Squirrels were placed in an enclosed box with gridded lines and holes. Mirror: Squirrels are presented with their mirror image, which they do not recognize as their own.   Flight initiative: Squirrels were approached slowly in the wild to see how long they wait before running away. Behavior-in-trap: Squirrels were caught, unharmed, in a simple trap and their behavior briefly observed. The social squirrel’s advantage Overall, the study found that bolder squirrels had larger core areas where they concentrated their activity. Bold, active squirrels moved faster. Also, squirrels that were bolder, more aggressive and more active had greater access to perches, such as rocks. Perch access is important because it can provide a better vantage point for seeing and evading predators. Interestingly, perch access was also associated with sociability. A golden-mantled ground squirrel looks at its reflection in a mirror simulation experiment by UC Davis. Credit: Jaclyn Aliperti, UC Davis Golden-mantled ground squirrels are considered an asocial species. They are relatively small, giving them little opportunity to form the tighter social bonds common in larger ground squirrels, which typically spend more time in family units while reaching maturity. However, the study said that “within this asocial species, individuals that tend to be relatively more social seem to have an advantage.” In such cases, being more social could save an individual’s life. Such personality differences can influence a squirrel’s ability to survive and reproduce, which could scale up to the population or community level. Squirrels of Davis UC Davis is home to many squirrels, which have become an honorary mascot of sorts on campus. “The squirrels of UC Davis are something else,” said Aliperti. She means it literally. They are tree squirrels and very different from the ground squirrels Aliperti studied. Yet she says her work has changed how she views the squirrels of Davis. “I view them more as individuals,” Aliperti said. “I view them as, ‘Who are you? Where are you going? What are up to?’ versus on a species level.” Noticing such individuality brings a more personal angle to viewing wildlife. “Animal personality is a hard science, but if it makes you relate to animals more, maybe people will be more interested in conserving them,” said Aliperti.

A new study suggests that the evolution of the human brain’s increased size may be attributed to the consumption of fermented foods, offering an alternative to the theory that cooking was the key driver. This dietary shift likely provided the necessary nutrition to support a larger brain, with implications for future research in human health and evolution. The study hypothesizes that ‘pre-digested’ foods contributed to the development of larger brains. The large, capable human brain is a marvel of evolution, but how it evolved from a smaller primate brain into the creative, complex organ of today is a mystery. Scientists can pinpoint when our evolutionary ancestors evolved larger brains, which roughly tripled in size as human ancestors evolved from the bipedal primates known as Australopithecines. But why it happened when it did – what spurred that change – has remained elusive. While some have theorized that the use of fire, and the subsequent invention of cooking, gave our ancestors enough nourishment for our larger-brained ancestors to become dominant, a new theory points to a different spark: fermentation. The Role of Diet in Brain Evolution The key to understanding how our brains grew is most likely rooted in what – and how – we eat, said Erin Hecht, one of the authors of the study which was recently published in Nature Communications Biology. “Brain tissue is metabolically expensive,” said the Human Evolutionary Biology assistant professor.  “It requires a lot of calories to keep it running, and in most animals, having enough energy just to survive is a constant problem.” For larger-brained Australopiths to survive, therefore, something must have changed in their diet. Theories put forward have included changes in what these human ancestors consumed or, most popularly, that the discovery of cooking allowed them to garner more usable calories from whatever they ate. A diagrammatic representation of the External Fermentation Hypothesis. Credit: Erin Hecht But the problem with this theory is that the earliest evidence places the use of fire at approximately 1.5 million years ago – significantly later than the development of the hominid brain. “Our ancestors’ cranial capacity began increasing 2.5 million years ago, which conservatively gives us about a 1-million-year gap in the timeline between brain size increasing and the possible emergence of cooking technology,” explained Katherine L. Bryant, one of the paper’s co-authors and currently a researcher at the Institute for Language, Communication, and the Brain at Aix-Marseille Université in France. “Some other dietary change must have been releasing metabolic constraints on brain size, and fermentation seems like it could fit the bill.” Added Hecht: “Whatever changed in their diets had to have happened before brains started getting bigger.” Fermentation: A New Perspective on Brain Growth She continued, noting that during the last few years, researchers have postulated other options, such as the consumption of rotting meat. In this new paper, Hecht and her team offer a different hypothesis: that cached (or saved) food fermented, and that this “pre-digested” food provided a more accessible form of nourishment, fueling that bigger brain and allowing our larger-brained ancestors to survive and thrive through natural selection. The shift was probably a happy accident. “This was not necessarily an intentional endeavor,” Hecht posited. “It may have been an accidental side effect of caching food. And maybe, over time, traditions or superstitions could have led to practices that promoted fermentation or made fermentation more stable or more reliable.” This hypothesis is supported by the fact that the human large intestine is proportionally smaller than that of other primates, suggesting that we adapted to food that was already broken down by the chemical process of fermentation. In addition, fermented foods are found in all cultures and across food groups, from Europe’s wine and cheese to Asia’s soy sauce and natto, or soybeans. Hecht suggested that an additional study of brain responses to fermented and non-fermented foods might be useful, as might one of olfactory and taste receptors, perhaps using ancient DNA. For the evolutionary biologist, these are all fertile areas for other researchers to pick up on. (Hecht’s focus is more on “how brain circuits have evolved to support complex behaviors” with research on both living humans and dogs.) As research progresses, Bryant sees possibilities for a wide range of benefits. “This hypothesis also gives us as scientists even more reasons to explore the role of fermented foods on human health and the maintenance of a healthy gut microbiome,” she said. “There have been a number of studies in recent years linking gut microbiome to not only physical but mental health.” Reference: “Fermentation technology as a driver of human brain expansion” by Katherine L.
