“Peeking Into a Honey Bee Superorganism of Honey Bee Super Organisms!” Lake Vasey Word Count 983 1 “Peeking into a Honey Bee Superorganism of Honey Bee Super Organisms!” “See ya, I’m heading out to the hives!” I yell across the farm. Today, I’m slipping on my bee suit to visit a superorganism! You’re probably thinking that the individual honey bee is the super organism, since super organism is defined as an excellent living being.1 ​ ​ ​ However, did you know that the entire honey bee colony is considered a ​ ​ 2 superorganism? ​ As confusing as this may be, it opens up a whole new way of thinking ​ ​ about our amazing honey bees! What exactly is a superorganism and what does this mean to me, my community, and my world? I’ll explain as I ‘buzz on’ back to my beehives. A superorganism is an organism consisting of many organisms, and the term is ... ​ ​ used to describe a social unit of eusocial animals such as honey bees, ... which have highly organized division of labor, and where [individual honey bees aren’t] able to 3 survive by themselves for any length of time. ​ University of Delaware Entomology ​ Professor Deborah Delaney stated during our interview, “Quite fascinating is that even though the individual honey bee organism is super, it isn’t nearly as super as the entire colony of honeybees functioning like a single superorganism.” Together as one body, the honey bees communicate with each other about scouting for pollen, regulating hive temperature, food storage, reproduction, self-defense, and swarming. According​ to ​ Professor of Entomology and honey bee expert Dr. Keith Delaplane, ... think of the hive ... as a total functioning body with the ovaries being the queen; the testes being the drones; the body being the workers; the liver being the beeswax, and the uterus being 4 the brood cells. Delap​ lane explains that the [beeswax] comb is the liver of the hive, ... ​ Vasey/2 5 [since] it absorbs the dirt, the chemicals, the bee footprints, [and] the cocoons. There​ is ​ indeed a super advantage to being a superorganism! ​ Have you ever wondered why ​ exactly a honey bee colony is considered super to us? Let’s peek inside a colony to look into this treasure trove of many health benefits! I’m excited to check-in on this superorganism of super organisms! It may seem crazy, but I consider each hive a medicine cabinet. Prying open this hive is tricky since the ‘glue-ish’ propolis holds the lid tight! Propolis has proven antibiotic and antiseptic 6 7 properties ... ​ [and] can be considered extremely useful in cancer treatment. ​ Next, I ​ ​ 8 see pollen, which is richer in proteins than any animal source. Pollen​ not only boosts ​ energy but also treats addictions by crashing cravings and boosts the immune system!9 ​ Finally, I find honey- the only food that includes all the substances necessary to sustain life, including enzymes, vitamins, minerals, and water; and it's the only food that contains "pinocembrin", an antioxidant associated with improved brain functioning.10 ​ Like many people, I’m hoping to desensitize my allergies with honey. By eating local honey, a person is eating the local pollen. Over time, a person may become less 11 sensitive to this pollen ... and experience fewer allergy symptoms. ​ Also, many people ​ in our community have told us that our honey is what helped them through their winter sicknesses! Honey contains super ... antibacterial properties which aid in healing.12 ​ Worldwide, honey is used medicinally for many ailments, including abrasions, ... 13 infections, ... sinusitis, burns, ... and urinary tract infections. ​ The medicinal benefits ​ are super, however, there is a greater reason why the world needs our honey bee colonies. Vasey/3 The biggest reason for needing these superorganisms is that our world’s food supply depends on it. One out of every three bites of food that we put in our mouths is 14 put there by pollinators. ​ According to the USDA, the honeybee is responsible for 80 ​ 15 percent of that pollination. Honey​ bee colonies are dying by the millions and that could ​ 16 spell higher food prices at the store. Stepping​ back from my hive to look out over our ​ farm, I admire the fruit and vegetable pollination work that these colonies have accomplished! There will be plenty of produce to bring to our market and appreciated by our community. Time to close my hive to protect it from the weather! Unfortunately, there are many other mysterious dangers to my colonies and for colonies across the world. Mr. Tim Miller, the beekeeper of Wampler Honey, told me, “I lost 130 hives last year and 200 the year before.” Research will help discover what is causing the collapse of these superorganisms and will help us to protect them. Scientists of EPA, USDA, and ... global [scientists] ... [believe] that the ... declining health of honey bees is related to ... pests, ... pathogens, ... viruses, poor nutrition, ... pesticide exposure, bee management practices, ... and lack of genetic diversity. 17 ​ Protecting our honey bee colonies should be on everyone’s mind. Mr. Miller said, “ Everyone can help by using fewer chemicals in yards, planting bee-friendly plants, and by keeping bees!” I also strongly believe in educating our communities around the world about “bee-safe” pesticide use. During our community farmers’ markets, I inform customers to never allow car fluids, chemicals, or mosquito tablets to go into puddles because the honey bees drink the same water. I’ve advised my Vasey/4 neighbor, Mr. Frank, to never use pesticide garden dust, since it mimics pollen. We don’t want to risk honey bees bringing the toxic dust back to the hive. Deborah Delaney stated, “We need to learn the honey bees’ biology, learn how they interact with the environment, and give them safe requirements of nectar, water, and pollen.” Essentially, everyone will be helping themselves by helping to protect this great honey bee superorganism! Isn’t a trip back to the hives exciting? Chatting about the importance of our honey bees and how to keep them healthy is always front page news! It’s been great visiting with my honey bee super organisms, but an even greater experience with my colony superorganism! Now- to get out of this hot bee suit... Vasey/5 ENDNOTES 1.

  • Warfare in an Evolutionary Perspective
    Received: 26 November 2018 Revised: 7 May 2019 Accepted: 18 September 2019 DOI: 10.1002/evan.21806 REVIEW ARTICLE Warfare in an evolutionary perspective Bonaventura Majolo School of Psychology, University of Lincoln, Sarah Swift Building, Lincoln, UK Abstract The importance of warfare for human evolution is hotly debated in anthropology. Correspondence Bonaventura Majolo, School of Psychology, Some authors hypothesize that warfare emerged at least 200,000–100,000 years BP, University of Lincoln, Sarah Swift Building, was frequent, and significantly shaped human social evolution. Other authors claim Brayford Wharf East, Lincoln LN5 7AT, UK. Email: [email protected] that warfare is a recent phenomenon, linked to the emergence of agriculture, and mostly explained by cultural rather than evolutionary forces. Here I highlight and crit- ically evaluate six controversial points on the evolutionary bases of warfare. I argue that cultural and evolutionary explanations on the emergence of warfare are not alternative but analyze biological diversity at two distinct levels. An evolved propen- sity to act aggressively toward outgroup individuals may emerge irrespective of whether warfare appeared early/late during human evolution. Finally, I argue that lethal violence and aggression toward outgroup individuals are two linked but distinct phenomena, and that war and peace are complementary and should not always be treated as two mutually exclusive behavioral responses. KEYWORDS aggression, competition, conflict, cooperation, peace, social evolution, violence, war 1 | INTRODUCTION and others on the importance of organized/cooperative actions among members of one social group against members of the opposing The question of whether humans are innately peaceful or aggressive group.5 Clearly, how we define warfare affects how deep we can go has fascinated scientists and philosophers for centuries.1,2 Wars, eth- back in time in human evolution to investigate its emergence and evo- nic or religious contests, and intra-group or intra-family violence are lutionary bases.

Its center-stage is “the genome,” where social and environmental information and genetic variation interact to influence social behavior through dynamic shifts in gene expression across multiple bodies and time-scales. With the advent of whole-genome sequencing technology, comparative genomics, and computational tools for mining patterns of association across widely disparate datasets, social insects are being experimented with to identify genetic networks underlying autism, novelty-seeking and aggression evolutionarily shared with humans. Drawing on the writings of key social insect biologists, and historians and philosophers of science, I investigate how the historical development of social insect research on wasps, ants and bees shape central approaches in sociogenomics today, in particular, with regards to shifting understandings of “the individual” in relation to “the social.” Keywords: sociogenomics; social insect; sociobiology; postgenomics; biology and society © 2019 Sainath Suryanarayanan.

Recent data data suggest that honey bees appear to be less susceptible to [14 ,15 ] suggest that eusocial honey bees appear to stressors compared to other species. Here we argue that be less susceptible to stressors compared to bumblebees eusociality plays a key role for the susceptibility of insects to and solitary bee species; this might be due to different environmental stressors due to what we call superorganism abilities to detoxify and thus withstand pesticide stress resilience, which can be defined as the ability to tolerate the [15 ,16]. However, regardless of potential differences in loss of somatic cells (=workers) as long as the germ line the ability of individuals to tolerate environmental stress- (=reproduction) is maintained.

Future conservation efforts history as fundamental biological factors that govern should take superorganism resilience into account to the buffering capacity of insect species (Figure 1).

  • Growth and Survival of the Superorganism: Ant Colony
    Growth and survival of the superorganism: ant colony macronutrient intake and investment Yeisson Guti´errez1, Tung Phung2, Harald Mumma2, Arden Ambrose-Winters2, Christoph Scherber3, and Chris Smith2 1University of M¨unster 2Earlham College 3Westf¨alische Wilhelms-Universit¨atM¨unster May 5, 2020 Abstract In this study, we used two common ant species (Lasius niger and L. neoniger) to assay how they translate variation in the diet (both in composition and frequency) into growth. We measured colony development for over 8 months and measured several phenotypic traits of the worker caste, and examined whether forager preference corresponded with diet quality. Individuals (workers) and colonies (superorganisms) increased in size with increasing amounts of protein in the diet, and as a function of how much food was available. Optimal colony growth was a balance between survival and growth, and each of these were maximized with different nutrient regimes. Interestingly, forager preference was not totally aligned with the diet that maximized colony growth. Our results highlight that: 1) organism and superorganism size are controlled by the same nutrients, and this may reflect a common molecular basis for size across life’s organizational levels, 2) there are nutrient trade-offs that are associated with life-history trade-offs, likely leading to selection for a balanced diet, and 3) the connection between the preference of foragers for different nutrients and how nutrient combinations affect colony success and demographics are complex and only beginning to be understood. INTRODUCTION Nutrition is an upstream organizer of most organismal processes, and thus dealing with variation in the availability of nutrients is among the most consequential challenges, and selective agents, faced by all or- ganisms (Stearns, 1992; Zera & Harshman, 2001).

  • Built for Speed, Not for Comfort
    Darwinian Evolutionary Ethics: Between Patriotism and Sympathy Peter J. Richerson and Robert Boyd Summary Darwin believed that his theory of evolution would stand or fall on its ability to account for human behavior. No species could be an exception to his theory without imperiling the whole edifice. One of the most striking features of human behavior is our very elaborate social life involving cooperation with large numbers of other people. The evolution of the ethical sensibilities and institutions of humans was thus one of his central concerns. Darwin made four main arguments regarding human morality: (1) that it is a product of group selection; (2) that an immense difference existed between human moral systems and those of other animals; (3) that the human social instincts were “primeval” and essentially the same in all modern humans; and (4) that moral progress was possible based on using the instinct of sympathy as the basis for inventing and favoring the spread of improved social institutions. Modern studies of cultural evolution suggest that Darwin’s arguments about the evolution of morality are largely correct in their essentials. Submitted for inclusion in Evolutionary Ethics: Biological and Theological Perspectives on Human Morality, Philip Clayton and Jeffrey Schloss, editors Copyright 2003 Peter J. Richerson and Robert Boyd Introduction Darwin believed that his theory of evolution by natural and sexual selection would stand or fall on its ability to account for human behavior. No species could be an exception to his theory without imperiling the whole edifice (Gruber 1974: Chapter 10). He thus eventually devoted the Descent of Man to developing an evolutionary account of human origins based on selection, but also on the inheritance of acquired variation.

  • Venom and Social Behavior: the Potential of Using Spiders to Evaluate the Evolution of Sociality Under High Risk
    toxins Review Venom and Social Behavior: The Potential of Using Spiders to Evaluate the Evolution of Sociality under High Risk Laura Gatchoff * and Laura R. Stein Department of Biology, University of Oklahoma, Norman, OK 73019, USA; [email protected] * Correspondence: [email protected] Abstract: Risks of sociality, including competition and conspecific aggression, are particularly pro- nounced in venomous invertebrates such as arachnids. Spiders show a wide range of sociality, with differing levels of cannibalism and other types of social aggression. To have the greatest chance of surviving interactions with conspecifics, spiders must learn to assess and respond to risk. One of the major ways risk assessment is studied in spiders is via venom metering, in which spiders choose how much venom to use based on prey and predator characteristics. While venom metering in response to prey acquisition and predator defense is well-studied, less is known about its use in conspecific interactions. Here we argue that due to the wide range of both sociality and venom found in spiders, they are poised to be an excellent system for testing questions regarding whether and how venom use relates to the evolution of social behavior and, in return, whether social behavior influences venom use and evolution. We focus primarily on the widow spiders, Latrodectus, as a strong model for testing these hypotheses. Given that successful responses to risk are vital for maintaining sociality, comparative analysis of spider taxa in which venom metering and sociality vary can provide valuable insights into the evolution and maintenance of social behavior under risk.
