Biology Scientific Love Quotes

Contrary to what many of us are told, Israel’s origin stories weren’t designed to answer scientific, twenty-first-century questions about the beginning of the universe or the biological evolution of human beings, but rather were meant to answer then-pressing, ancient questions about the nature of God and God’s relationship to creation.

It is far better to make them live in the Future. Biological necessity makes all their passions point in that direction already, so that thought about the Future inflames hope and fear. Also, it is unknown to them, so that in making them think about it we make them think of unrealities. In a word, the Future is, of all things, the thing least like eternity. It is the most completely temporal part of time—for the Past is frozen and no longer flows, and the Present is all lit up with eternal rays. Hence the encouragement we have given to all those schemes of thought such as Creative Evolution, Scientific Humanism, or Communism, which fix men’s affections on the Future, on the very core of temporality. Hence nearly all vices are rooted in the future. Gratitude looks to the past and love to the present; fear, avarice, lust, and ambition look ahead. Do

I don't believe, for instance, that evolutionary biology or any scientific endeavor has much to say about love. I'm sure a lot can be learned about the importance of hormones and their effects on our feelings. But do the bleak implications of evolution have any impact on the love I feel for my family? Do they make me more likely to break the law of flaunt society's expectations of me? No. I simply does not follow that human relationships are meaningless just because we live in a godless universe subject to the natural laws of biology.

When describing both the act of defecating and the substance of fecal matter itself, biologists prefer to use the scientific term "poop." It's both a noun and a verb. A popular field of biology called scatology is the study of scat, which is not to be confused with mere poop. Although technically they're the same, we call it "scat" if we are studying it to learn something about the health and diet of an animal. When the animal has pooped on us or has ruined something with his pooping, we tend to use the term "shit," as in, "Oh, man, he just shit down the back of my neck." So if it's on the ground, it's poop. If it's under your microscope, it's scat. If it's running down your neck, it's shit.

Despite the intervening six decades of scientific inquiry since Selye’s groundbreaking work, the physiological impact of the emotions is still far from fully appreciated. The medical approach to health and illness continues to suppose that body and mind are separable from each other and from the milieu in which they exist. Compounding that mistake is a definition of stress that is narrow and simplistic. Medical thinking usually sees stress as highly disturbing but isolated events such as, for example, sudden unemployment, a marriage breakup or the death of a loved one. These major events are potent sources of stress for many, but there are chronic daily stresses in people’s lives that are more insidious and more harmful in their long-term biological consequences. Internally generated stresses take their toll without in any way seeming out of the ordinary. For those habituated to high levels of internal stress since early childhood, it is the absence of stress that creates unease, evoking boredom and a sense of meaninglessness. People may become addicted to their own stress hormones, adrenaline and cortisol, Hans Selye observed. To such persons stress feels desirable, while the absence of it feels like something to be avoided. When people describe themselves as being stressed, they usually mean the nervous agitation they experience under excessive demands — most commonly in the areas of work, family, relationships, finances or health. But sensations of nervous tension do not define stress — nor, strictly speaking, are they always perceived when people are stressed. Stress, as we will define it, is not a matter of subjective feeling. It is a measurable set of objective physiological events in the body, involving the brain, the hormonal apparatus, the immune system and many other organs. Both animals and people can experience stress with no awareness of its presence. “Stress is not simply nervous tension,” Selye pointed out. “Stress reactions do occur in lower animals, and even in plants, that have no nervous systems…. Indeed, stress can be produced under deep anaesthesia in patients who are unconscious, and even in cell cultures grown outside the body.” Similarly, stress effects can be highly active in persons who are fully awake, but who are in the grip of unconscious emotions or cut off from their body responses. The physiology of stress may be triggered without observable effects on behaviour and without subjective awareness, as has been shown in animal experiments and in human studies.

In my own field, I know that solid science can easily be done with ethics and compassion. There's nothing wrong with compassionate or sentimental science or scientists. Studies of animal thought, emotions, and self-awareness, as well as behavioral ecology and conservation biology, can all be compassionate as well as scientifically rigorous. Science and the ethical treatment of animals aren't incompatible. We can do solid science with an open mind and a big heart. I encourage everyone to go where their hearts take them, with love, not fear. If we all travel this road, the world will be a better place for all beings. Kinder and more humane choices will be made when we let our hearts lead the way. Compassion begets compassion and caring for and loving animals spills over into compassion and caring for humans. The umbrella of compassion is very important to share freely and widely.

The traditional hospital practice of excluding parents ignored the importance of attachment relationships as regulators of the child’s emotions, behaviour and physiology. The child’s biological status would be vastly different under the circumstances of parental presence or absence. Her neurochemical output, the electrical activity in her brain’s emotional centres, her heart rate, blood pressure and the serum levels of the various hormones related to stress would all vary significantly. Life is possible only within certain well-defined limits, internal or external. We can no more survive, say, high sugar levels in our bloodstream than we can withstand high levels of radiation emanating from a nuclear explosion. The role of self-regulation, whether emotional or physical, may be likened to that of a thermostat ensuring that the temperature in a home remains constant despite the extremes of weather conditions outside. When the environment becomes too cold, the heating system is switched on. If the air becomes overheated, the air conditioner begins to work. In the animal kingdom, self-regulation is illustrated by the capacity of the warm-blooded creature to exist in a broad range of environments. It can survive more extreme variations of hot and cold without either chilling or overheating than can a coldblooded species. The latter is restricted to a much narrower range of habitats because it does not have the capacity to self-regulate the internal environment. Children and infant animals have virtually no capacity for biological self-regulation; their internal biological states—heart rates, hormone levels, nervous system activity — depend completely on their relationships with caregiving grown-ups. Emotions such as love, fear or anger serve the needs of protecting the self while maintaining essential relationships with parents and other caregivers. Psychological stress is whatever threatens the young creature’s perception of a safe relationship with the adults, because any disruption in the relationship will cause turbulence in the internal milieu. Emotional and social relationships remain important biological influences beyond childhood. “Independent self-regulation may not exist even in adulthood,” Dr. Myron Hofer, then of the Departments of Psychiatry and Neuroscience at Albert Einstein College of Medicine in New York, wrote in 1984. “Social interactions may continue to play an important role in the everyday regulation of internal biologic systems throughout life.” Our biological response to environmental challenge is profoundly influenced by the context and by the set of relationships that connect us with other human beings. As one prominent researcher has expressed it most aptly, “Adaptation does not occur wholly within the individual.” Human beings as a species did not evolve as solitary creatures but as social animals whose survival was contingent on powerful emotional connections with family and tribe. Social and emotional connections are an integral part of our neurological and chemical makeup. We all know this from the daily experience of dramatic physiological shifts in our bodies as we interact with others. “You’ve burnt the toast again,” evokes markedly different bodily responses from us, depending on whether it is shouted in anger or said with a smile. When one considers our evolutionary history and the scientific evidence at hand, it is absurd even to imagine that health and disease could ever be understood in isolation from our psychoemotional networks. “The basic premise is that, like other social animals, human physiologic homeostasis and ultimate health status are influenced not only by the physical environment but also by the social environment.” From such a biopsychosocial perspective, individual biology, psychological functioning and interpersonal and social relationships work together, each influencing the other.

All scientists, regardless of discipline, need to be prepared to confront the broadest consequences of our work—but we need to communicate its more detailed aspects as well. I was reminded of this at a recent lunch I attended with some of Silicon Valley’s greatest technology gurus. One of them said, “Give me ten to twenty million dollars and a team of smart people, and we can solve virtually any engineering challenge.” This person obviously knew a thing or two about solving technological problems—a long string of successes attested to that—but ironically, such an approach would not have produced the CRISPR-based gene-editing technology, which was inspired by curiosity-driven research into natural phenomena. The technology we ended up creating did not take anywhere near ten to twenty million dollars to develop, but it did require a thorough understanding of the chemistry and biology of bacterial adaptive immunity, a topic that may seem wholly unrelated to gene editing. This is but one example of the importance of fundamental research—the pursuit of science for the sake of understanding our natural world—and its relevance to developing new technologies. Nature, after all, has had a lot more time than humans to conduct experiments! If there’s one overarching point I hope you will take away from this book, it’s that humans need to keep exploring the world around us through open-ended scientific research. The wonders of penicillin would never have been discovered had Alexander Fleming not been conducting simple experiments with Staphylococci bacteria. Recombinant DNA research—the foundation for modern molecular biology—became possible only with the isolation of DNA-cutting and DNA-copying enzymes from gut- and heat-loving bacteria. Rapid DNA sequencing required experiments on the remarkable properties of bacteria from hot springs. And my colleagues and I would never have created a powerful gene-editing tool if we hadn’t tackled the much more fundamental question of how bacteria fight off viral infections.

The scientific basis for separating neocortical from limbic brain matter rests on solid neuroanatomical, cellular, and empirical grounds. As viewed through the microscope, limbic areas exhibit a far more primitive cellular organization than their neocortical counterparts. Certain radiographic dyes selectively stain limbic structures, thus painting the molecular dissimilarity between the two brains in clean, vivid strokes. One researcher made an antibody that binds to cells of the hippocampus—a limbic component—and found that those same fluorescent markers stuck to all parts of the limbic brain, lighting it up like a biological Christmas tree, without coloring the neocortex at all. Large doses of some medications destroy limbic tissue while leaving the neocortex unscathed, a sharp-shooting feat enabled by evolutionary divergence in the chemical composition of limbic and neocortical cell membranes.

I wanted to help rescue this species from endangerment by learning about the elephants’ intricate social structure, increasing worldwide attention to this species through my research and scientific advancements in knowledge. However, when the scientific papers that I had spent years writing finally came out, there was little reaction. I felt proud of my scientific accomplishments but was sad that I wasn’t doing more for the species that I cared about so much. The following year after I graduated, a new paper by one of my colleagues in Gabon found that between 2002-2011, the duration of my Ph.D. plus a few years, over 60% of the entire forest elephant population declined due to poaching[5]. The poaching was almost exclusively driven by the consumption of their tusks as sources for carving statues, jewelry, and other decorative objects. The true conservation issue had nothing to do with studying the elephants themselves. What was the point of studying a species if it might not exist in a few decades?  If I really wanted to help forest elephants, I should have been studying the people, the consumers who were purchasing ivory to determine if there were ways to change attitudes towards ivory and purchasing behavior. Yes, having rangers on the ground to protect parks and elephants is important, but if there is no decrease in demand, it will constantly be an uphill battle. All of the solutions to the conservation problems of forest elephants are social, political, and economic first.  If you are interested in pursuing wildlife biology as a career for conservation purposes (like I was) or because you love animals (also me), you might be better suited in another career if research is not your thing but can still work for a conservation organization. Nonprofits need lawyers, financial planners, fundraising experts, and marketing executives to name a few. When I perused the job boards of nonprofit organizations, I was surprised by how few research positions there were. There were far more in fundraising, marketing, and development. Even if you don’t work directly for conservation, honestly, you can still make a difference and help conservation efforts in other ways outside of your career. A lot of conservation is really about investing in programs and habitat, so species stay protected. For example, if you can purchase and/or donate money to organizations that buy large areas of land, this land can be set aside for wildlife conservation. The biggest threat to wildlife is habitat loss and simply buying more land, keeping it undeveloped, and/or restoring it for species to live on, is one of the major means to solve the biodiversity crisis.

Bruce conducted some groundbreaking experiments showing that our genes do not control biology. The idea that genes control biology is a faulty scientific assumption that was debunked by the Human Genome Project around the year 2003, a
