    • Understanding Animal Gender and SexualityAnimals engage in sexual behavior for reasons beyond reproduction, including social bonding and political purposes. Bonobos use sex for greeting, reconciliation, and maintaining dominance.

      Animals, including primates like bonobos, have their unique ways of understanding gender and sexuality, which can provide valuable insights into human behavior. While it's natural for us to compare them to humans, it's essential to remember that animals, such as bonobos, engage in sexual behavior for various reasons beyond reproduction, including social bonding and political purposes. Bonobos, for instance, are known for their frequent sexual interactions, but they are brief and serve as a form of greeting or reconciliation. Their society is female-dominated, and females use sex to strengthen their bonds and maintain dominance over males. This collective dominance serves a protective purpose, as females band together to guard against harassment and infanticide from males. By recognizing the complexity of animal sexual behavior and gender dynamics, we can broaden our understanding of these concepts and appreciate the richness and diversity of life on our planet.

    • Understanding Bonobos: Sex, Social Structure, and Emotional ConnectionsBonobos, our close primate relatives, have a unique social structure that relies on collective behavior, emotional connections between females, and sexual relationships to maintain harmony and protect offspring. Their large clitorises reflect the social importance of sex.

      The social structure of bonobos, our close primate relatives, is unique in that it relies on collective behavior and sexual relationships between females to maintain harmony and protect their offspring. Studies have shown that females experience more emotional connection and greater satisfaction during sexual encounters with other females. The large clitoris in bonobos and dolphins is a reflection of the important social role sex plays in these species. Researchers study bonobos in various settings, including zoos, sanctuaries, and the wild, using a combination of observation and experimentation to understand their behavior. Bonobos exhibit gender roles that are influenced by learning from each other, suggesting a significant cultural component to their behavior. Instead of viewing sex differences as purely biological, it's important to consider the role of culture and learning in shaping their behaviors.

    • Understanding Gender and Sex in PrimatesBoth biology and environment shape gender development in primates, including humans. Self-socialization, or learning from peers and role models, is a significant factor in the development of gender roles.

      Gender and sex are two distinct concepts, with sex being biologically determined and gender being culturally and socially constructed. Primates, including humans, exhibit both biological sex and culturally learned gender roles. The nature versus nurture debate on the origins of gender differences is ongoing, and it's challenging to separate the two. The media often oversimplifies the issue by attributing certain traits to genetics, but the reality is more complex. Both nature and nurture play a role, and it's difficult to determine which part is which. Self-socialization, or learning from peers and role models, is an essential concept in understanding gender development in primates, including humans. Children look for models based on their gender identity and learn behaviors accordingly. In the case of primates, young males and females exhibit different behaviors due to observing adult males and females, respectively. This self-socialization along gender lines is crucial in understanding the development of gender roles in primates and humans.

    • Challenging the Binary Notion of Gender in Primate SocietiesPrimate societies exhibit a spectrum of gender identities and behaviors, challenging the binary notion of gender. Individuals sometimes exhibit traits typically associated with the opposite sex, and these nonconformities do not typically cause intolerance or disturb the peace.

      Primate societies, like human societies, exhibit a spectrum of gender identities and behaviors, with individuals sometimes exhibiting traits typically associated with the opposite sex. For instance, Donna, a female chimpanzee, grew up acting and looking more like a male, and was even preferred by the alpha male for wrestling and displaying dominant behavior. This challenges the binary notion of gender and suggests that primate societies may be more accepting of gender diversity than human societies. Additionally, primates do not seem to exhibit the same level of intolerance towards gender nonconformity as humans do, as these individuals do not typically cause trouble or disturb the peace. Ultimately, the study of gender in primates could shed light on the flexibility and complexity of gender as a concept, and the potential for more accepting and inclusive societies.

    • Understanding primate social structuresEmpathy is a common trait in primates and other animals, but morality goes beyond empathy and includes reasoning, consensus building, enforcement, and guilt feelings.

      While primates, including chimpanzees and bonobos, exhibit in-group, out-group distinctions, this is not necessarily based on external features such as color. Instead, it's about belonging. Bonobos, for instance, have a more peaceful coexistence with other groups, while chimpanzees have varying degrees of hostility. Empathy, a central part of moral philosophy, is a well-accepted concept in animals, including primates. However, morality involves more than just empathy, such as reasoning about moral rules, consensus building, enforcement, and guilt feelings. Empathy is found in most primates and mammals, and even birds, suggesting that some building blocks of human morality can be found in other species.

    • Empathy and cooperation in social speciesEmpathy, regulated by oxytocin, allows animals to understand emotions and needs. Cooperation, essential for survival, takes various forms and requires social intelligence.

      Empathy and cooperation are important characteristics in the animal world, particularly in social species like primates, chimpanzees, elephants, and dolphins. Empathy, which is regulated by the hormone oxytocin and developed from maternal care, allows animals to understand and respond to the emotions and needs of others. Cooperation, which is essential for survival in many species, can take various forms, from simple warning systems to targeted helping based on an understanding of the situation of the other. These behaviors require a level of social intelligence and theory of mind, allowing animals to understand their own and others' needs and perspectives. While cooperation is found throughout the animal kingdom, targeted helping and perspective-taking are more advanced behaviors that set social species apart. Researchers observe these behaviors through spontaneous observations and controlled experiments, although conducting experiments in the field can be challenging.

    • Primates exhibit altruism and cooperation, even towards strangersPrimates, like bonobos and chimpanzees, practice sharing and fairness in their societies, ensuring equitable distribution of resources to maintain cooperation.

      Primates, including bonobos and chimpanzees, display altruistic behavior and cooperation, even towards strangers. For instance, a study showed that bonobos were willing to release food for another bonobo, even without receiving anything in return. Both species primarily consume fruits, leaves, and meat, with chimpanzees hunting cooperatively and bonobos being less cooperative hunters. The hunting behavior of chimpanzees involves a role division, with experienced males acting as blockers to drive monkeys towards other hunters. Sharing the prey after hunting is crucial for maintaining cooperation. This concept of sharing and equity is also seen in studies on the sense of fairness in monkeys and apes. It's essential for a cooperative society to ensure equitable distribution of resources, or else, it could lead to tensions and potential societal unrest. The famous fairness experiments, like the grapes and cucumbers test, showed that monkeys paid attention to what others received and reacted accordingly, highlighting their awareness of fairness.

    • Monkeys value fairness in social interactionsMonkeys and potentially other social animals exhibit a strong sense of fairness, refusing rewards if others receive unequal treatment.

      Monkeys, and potentially other social animals, exhibit a strong sense of fairness. This was demonstrated in an experiment where one monkey received cucumber slices and the other received grapes for the same task. The monkey receiving cucumber became upset and refused to continue if the other monkey received grapes. This behavior was not due to an irrational response but rather a desire for fairness and equality. Chimpanzees even go a step further and will refuse their own reward until the other monkey receives an equal reward. This sense of fairness is more pronounced in cooperative primates and may be a result of their social nature and the understanding that future interactions are important. While this sense of fairness is present in humans as well, it may be less pronounced in large-scale societies due to anonymous relationships. The origins of this behavior in monkeys and humans are still being researched.

    • Primate Behavior and Ecology: Shaping Social Structures and AltruismPrimate behavior and social structures are influenced by ecological factors, with abundant food leading to female support and less competition resulting in more altruistic tendencies. Primates, including chimpanzees, exhibit altruistic behaviors towards each other, challenging the notion that animals cannot be truly selfless.

      The behavior and social structures of primates, such as bonobos and chimpanzees, are influenced by their ecological environments. For instance, the presence or absence of competitors like gorillas can significantly impact the way these primates live and interact with each other. Bonobos, who live in areas with abundant food and no gorillas, have a society where female support is crucial due to their ability to live together. In contrast, chimpanzees, who face competition from gorillas and must spread out to find food, have less female solidarity. However, research shows that primates, including chimpanzees, exhibit altruistic behavior towards each other, even in the absence of direct benefits or kin relations. Instances of chimpanzees helping each other against predators or rescuing each other from danger demonstrate their capacity for selflessness and kindness. These behaviors challenge the long-held belief that animals cannot be truly altruistic. Moreover, altruistic behaviors have been observed in various other species, including dolphins, which further underscores the prevalence of such tendencies in the animal kingdom. Overall, the discussion highlights the importance of understanding the ecological contexts that shape primate behavior and the significance of recognizing the altruistic capacities of animals.

    • Empathy's Wider ApplicationEmpathy, which developed for inner circles, can be used beyond them for various purposes. For example, dolphins show empathy towards human swimmers, and color vision, which aided in fruit selection, can be used for other tasks.

      The capacity for empathy, which evolved for the benefit of inner circles and families, can be applied beyond those circles and situations where it initially developed. This was discussed in relation to dolphins and their behavior towards human swimmers. The gene-centric view of evolution often overlooks this fact, and it's important to remember that once a capacity has developed, it can be used for various purposes. For instance, color vision arose to help pick out ripe fruits but can also be used for other things like reading maps or choosing outfits. Similarly, cooperation, which arose for the benefit of groups, can be undermined by free riding or cheating, but primates have ways of dealing with it through partner choice. In the end, the system discourages bad behavior as individuals tend to choose partners who are cooperative and sharing.

    • The importance of empathy and keeping the peace in close-knit communitiesEmpathetic actions and maintaining peace in communities, even through enforcement, can lead to popularity and respect, while bullying and terrorizing may result in ostracism or even death.

      The size and complexity of modern societies may lead to a decrease in motivation to behave well towards others due to the lack of face-to-face contact and personal connections. However, the primate world, with its close-knit communities, shows that individuals who act empathetically and keep the peace, even if they enforce their position, are often popular and well-respected. Conversely, those who bully and terrorize others may face consequences, including being ostracized or even killed. This system of justice, based on reputation and group support, highlights the importance of leadership and power beyond physical dominance. In the animal kingdom, alpha females, who are often overlooked in discussions of power, can hold significant influence and power within their groups. This distinction between power and dominance challenges the notion that the natural order is one of male dominance over females.

    • Chimpanzees exhibit complex cognitive abilities, including planning and emotional intelligenceChimpanzees demonstrate planning abilities and emotional intelligence, with females holding significant influence through close relationships and physical means.

      Chimpanzees and other primates exhibit complex cognitive abilities, including the capacity for planning and emotional intelligence. The female chimpanzee "mama" held significant influence over the colony, as she could rally support for a male during power struggles. This was due to her ability to enforce her preference through physical means and her close relationships with other females. Chimpanzees have also been observed to engage in forward planning, as shown by a female bonobo who carried a heavy rock for 15 minutes before reaching a nut source and using the rock to crack the nuts. While it's unclear if chimpanzees dream about the future, their ability to plan suggests that they may have some capacity for future-oriented thinking. The debate between behaviorists and cognitive scientists continues regarding the extent to which animal behavior can be explained by associative learning and conditioning versus more complex cognitive processes. However, recent research has increasingly shown that cognitive explanations provide a more accurate understanding of animal behavior.

    • Limited understanding of primate behavior due to traditional invasive methodsNew noninvasive neuroscience techniques will provide a more comprehensive understanding of primate behavior and sexuality, revealing previously overlooked diversity and shifts in older primates' roles and behaviors.

      Our understanding of primate behavior, including their sexuality and gender roles, has been limited by the methods used to study them. Traditional invasive neuroscience methods, such as removing parts of the brain, have been largely replaced by noninvasive neuroscience techniques like neuroimaging. This new approach will allow for a more comprehensive understanding of primate behavior and sexuality, which has been previously overlooked due to societal discomfort and lack of research focus. The primate kingdom exhibits a wide range of sexual diversity, with behaviors and orientations varying among individuals and species. Older primates, particularly males, exhibit different behaviors and social roles compared to their younger counterparts, with older males becoming more friendly and less aggressive. This shift in behavior is linked to changes in testosterone levels and a focus on social connections rather than political alliances. The future of primate research lies in noninvasive methods, which will provide valuable insights into their complex behaviors and help bridge the gap between human and primate sexuality and gender roles.

    • Understanding humans through primatesStudying primates provides insights into human behavior and evolution, challenging assumptions and offering a more nuanced perspective

      Our connection to animals, particularly primates, can provide valuable insights into human behavior and evolution. For instance, the absence of menopause in chimpanzees challenges the theory that menopause evolved to allow grandmothers to support their daughters and grandchildren. However, it's crucial not to oversimplify the differences between humans and animals. We should avoid setting ourselves completely apart from the animal kingdom or assuming that everything humans do is cultural and everything animals do is instinctive. Instead, we should recognize the complex interplay between biology and culture in both species. By studying primates, we can gain a more nuanced understanding of ourselves and challenge some of the stories we tell about ourselves in psychology and other fields. Overall, the primate world offers a mirror that can help us see ourselves more clearly.

    272 | Leslie Valiant on Learning and Educability in Computers and People

    Science is enabled by the fact that the natural world exhibits predictability and regularity, at least to some extent. Scientists collect data about what happens in the world, then try to suggest "laws" that capture many phenomena in simple rules. A small irony is that, while we are looking for nice compact rules, there aren't really nice compact rules about how to go about doing that. Today's guest, Leslie Valiant, has been a pioneer in understanding how computers can and do learn things about the world. And in his new book, The Importance of Being Educable, he pinpoints this ability to learn new things as the crucial feature that distinguishes us as human beings. We talk about where that capability came from and what its role is as artificial intelligence becomes ever more prevalent.

    271 | Claudia de Rham on Modifying General Relativity

    Einstein's theory of general relativity has been our best understanding of gravity for over a century, withstanding a variety of experimental challenges of ever-increasing precision. But we have to be open to the possibility that general relativity -- even at the classical level, aside from any questions of quantum gravity -- isn't the right theory of gravity. Such speculation is motivated by cosmology, where we have a good model of the universe but one with a number of loose ends. Claudia de Rham has been a leader in exploring how gravity could be modified in cosmologically interesting ways, and we discuss the current state of the art as well as future prospects.

    43 | Matthew Luczy on the Pleasures of Wine
    Some people never drink wine; for others, it’s an indispensable part of an enjoyable meal. Whatever your personal feelings might be, wine seems to exhibit a degree of complexity and nuance that can be intimidating to the non-expert. Where does that complexity come from, and how can we best approach wine? To answer these questions, we talk to Matthew Luczy, sommelier and wine director at Mélisse, one of the top fine-dining restaurants in the Los Angeles area. Matthew insisted that we actually drink wine rather than just talking about it, so drink we do. Therefore, in a Mindscape first, I recruited a third party to join us and add her own impressions of the tasting: science writer Jennifer Ouellette, who I knew would be available because we’re married to each other. We talk about what makes different wines distinct, the effects of aging, and what’s the right bottle to have with pizza. You are free to drink along at home, with exactly these wines or some other choices, but I think the podcast will be enjoyable whether you do or not. Support Mindscape on Patreon or Paypal.

    18 | Clifford Johnson on What's So Great About Superstring Theory
    String theory is a speculative and highly technical proposal for uniting the known forces of nature, including gravity, under a single quantum-mechanical framework. This doesn't seem like a recipe for creating a lightning rod of controversy, but somehow string theory has become just that. To get to the bottom of why anyone (indeed, a substantial majority of experts in the field) would think that replacing particles with little loops of string was a promising way forward for theoretical physics, I spoke with expert string theorist Clifford Johnson. We talk about the road string theory has taken from a tentative proposal dealing with the strong interactions, through a number of revolutions, to the point it's at today. Also, where all those extra dimensions might have gone. At the end we touch on Clifford's latest project, a graphic novel that he wrote and illustrated about how science is done. Clifford Johnson is a Professor of Physics at the University of Southern California. He received his Ph.D. in mathematics and physics from the University of Southampton. His research area is theoretical physics, focusing on string theory and quantum field theory. He was awarded the Maxwell Medal from the Institute of Physics.

    Welcome to the November 2021 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). I take the large number of questions asked by Patreons, whittle them down to a more manageable size — based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good — and sometimes group them together if they are about a similar topic. Enjoy!
