Phi for All Posted December 20 Posted December 20 2 hours ago, Luc Turpin said: In my view, it is likely a combination of both factors: my limited understanding of specific scientific domains, and the broader human tendency to temporarily reject ideas that challenge deeply held beliefs. This, this right here is a big part of the problem. Science has NOTHING to do with "deeply held beliefs". Read that a few times, please. In science, you have to trust what you choose to believe, and evidence is what you can base your trust in. You don't "deeply hold" a belief in chemistry; you perform experiments that show you over and over how various chemicals interact. You don't need faith or wishful thinking, you need to trust what the science has shown you, until it shows you that you need a better explanation. You seem to really WANT scientists to be as guilty in their "belief system" as religious folks are. You really WANT science to be just another religion with believers who might be wrong. Science is different because it's not asking you to believe in something that can't be observed or quantified, and it gives you a rigorous methodology for examining evidence that either supports or falsifies an explanation. If you challenge a scientific explanation with actual evidence, if you can devise an experiment that shows the explanation isn't sufficient, and can support that among your peers with testable science, your challenge can't be ignored, especially if it's supported by maths.

Science has long peered into the universe through an objective lens, uncovering what appeared to be a mechanistic and material world, and presenting it as fact, not belief. This approach often overlooks the notion that the universe also harbors a subjective reality, one that may challenge these deeply held convictions. While science itself may be free of beliefs, scientists, like all individuals, are shaped by their upbringing, culture, emotions, and personal philosophies. These influences inevitably impact the interpretation of data, the formulation of research questions, and even the models used to understand the cosmos. History is filled with theories once accepted as irrefutable truth, only to be later questioned or overturned by new evidence—shifts that arise not solely from data, but from a reevaluation of beliefs about nature. As for subjectivity, the thoughts and emotions of individuals are not easily captured by material explanations. Many philosophical traditions have long argued that the subjective realm is as real as the objective world studied by science. There exists a tension between the mechanistic, objective world revealed by science and the subjective nature of reality—a tension that science often ignores or downplays. While science strives for objectivity, it is ultimately conducted by humans, whose beliefs and other influences inevitably shape their work.

You can do things that improved your survivability (some control over your fate) that are in no way controlling how your population evolves.
CharonY Posted December 20 Posted December 20 And this is especially apparent when we use a more precise definition of evolution focusing on gene pool changes. While behaviors influence reproductive success, they do not control as such how the composition of the next generation is going to be. That level of control is virtually only possible with specific and targeted breeding that overrides any other factor. With anything else, it becomes one of many factors, many of which are based on chance (such as, likelihood of finding a partner in the first place).
Luc Turpin Posted December 21 Author Posted December 21 (edited) Those that find me irrelevant and dismissible, should not read beyond this point. The main argument of the article, as indicated in the opening post, is that species have extraordinary ways of influencing their evolutionary fate. However, neither the post's author nor the article's author intends to suggest that organisms directly control their gene pool or have total control over their evolutionary course. Rather, the author of the main article emphasizes that non-genetic inheritance plays a significant role in evolvability, though not in the sense of having direct or total control over genetic changes. As for the author of the original post, he also suggests that behaviors may be within an organism's control, which can potentially affect their survival and reproduction, leading to changes in the gene pool. This aligns somewhat with CharonY's point that "behaviors influence reproductive success, but do not control how the composition of the next generation is going to be." To further explore this, it is important to first establish the possibility of intentional learned behaviors in nature. Intentional learned behaviors refer to actions that individuals consciously acquire through social interaction, education, or self-reflection, and that can be passed down across generations via social learning. The idea of intentionality in behaviors is well supported in research, particularly in the field of cultural evolution. Boyd and Richerson highlight that cultural behaviors, including intentional ones, can influence biological evolution by altering the environment in which selection pressures operate. Additionally, Csibra and Gergely discuss how human cognition is uniquely capable of intentional learning, which accelerates cultural transmission and transformation. Empirical studies, such as those by Michael Tomasello, demonstrate that humans as young as 12 months old engage in intentional learning through imitation, where they actively choose to learn specific behaviors. Moving on, it is also worth considering how behaviors influence an organism’s survivability and reproductive success. The orcas discussed in the article provide an example of learned behaviors that directly impact survivability. By learning to make waves to dislodge seals from shorelines, these orcas improve their access to food, thereby increasing their chances of survival and reproduction. Research supports this idea; for example, Stephens and Krebs emphasize that learned behaviors are essential for survival, enabling organisms to forage more efficiently, avoid predators, and mate more effectively. Studies on birds and bees further corroborate this. In an experiment by Krebs and Davis, birds adjusted their foraging strategies based on past experiences, leading to higher success rates in finding food and avoiding predators. Similarly, bees in Royer’s study learned to associate specific cues with the presence of predators, enhancing their chances of survival. Now, it’s clear that survival to reproductive age is critical in shaping the gene pool. Organisms that survive to reproduce pass on their genetic material to the next generation, while those that do not are effectively removed from the gene pool, a process known as natural selection. I argue that traits favoring cognitive flexibility, which in turn support learning, are part of the genetic material passed on to the next generation. For example, bees that can learn to forage more efficiently or avoid predators are more likely to survive and reproduce, thereby passing on genetic traits associated with better learning abilities (e.g., improved memory, neural efficiency). Over time, these cognitive traits may become more prevalent in the population. Boyd and Richerson suggest that cultural evolution, in which learned behaviors play a key role, influences human cognition and facilitates the transmission of cognitive traits across generations. In conclusion, I believe I have demonstrated that intentionaly learned behaviors exist, they can affect survivability and reproduction, and that survivability to reproduction ultimately shapes the gene pool. Cognitive traits related to learning, such as improved memory or neural efficiency, may indeed be passed down through generations, further supporting the role of learned behaviors in evolutionary processes.Through this indirect route to the gene pool, I also assert that I have demonstrated a form of partial and indirect control over it. Now, if there is possible control over the gene pool, is there then some sense of direction in evolution? Edited December 21 by Luc Turpin

I rather think these (mine and yours) are minor variations in the wider context of 'evolution' in the full. Wikipedia has several summary articles that cover some of the variations you raise, but not always in accordance with your explanations. I have highlighted a couple. Quote Wikipedia Evolution is not a random process. Although mutations in DNA are random, natural selection is not a process of chance: the environment determines the probability of reproductive success. Evolution is an inevitable result of imperfectly copying, self-replicating organisms reproducing over billions of years under the selective pressure of the environment. The outcome of evolution is not a perfectly designed organism. The end products of natural selection are organisms that are adapted to their present environments. Natural selection does not involve progress towards an ultimate goal. Evolution does not strive for more advanced, more intelligent, or more sophisticated life forms.[25] For example, fleas (wingless parasites) are descended from a winged, ancestral scorpionfly, and snakes are lizards that no longer require limbs—although pythons still grow tiny structures that are the remains of their ancestor's hind legs.[26][27] Organisms are merely the outcome of variations that succeed or fail, dependent upon the environmental conditions at the time. https://en.wikipedia.org/wiki/Introduction_to_evolution https://en.wikipedia.org/wiki/History_of_evolutionary_thought https://en.wikipedia.org/wiki/Evolution However you have entitled this thread 'evolving evolution', which implies change of some sort. So really it is worth starting right at the beginning. And the beginning is the use of the English word evolution to stand for a group of ideas. Interestingly the word evolution is borrowed from Science from its original English meaning and comes from the Latin 'evolutio'. This was Latin for the specific activity of unrolling a scroll, the origin of which is lost in antiquity since scrolls predated the Romans by at least a thousand years. But it is an interesting loan from the original English which applied it to unfurling sails several hundred years before its application in Science. OK so onwards towards its modern application. The first stage in the evolution of life involved single celled organisms. With a modern eye we can observe that each type of such organism had the same genes. Even today such simple organisms move away from danger - chemicals, radiation etc. Is that 'learning ?' are they cognitive ? or what? At some point these organisms developed or learned or what? the way to club together as multicellular organisms. Still simple, and still with all the same genes. Having done this the ability to specialise arrived so that they had a mechanism to switch off or on genes particular to their function as specialised cells. Later still a big development occurred as such multicellular groupings began to reproduce so there there were then (larger) multicellular organisms with different gene sets. This marked a huge change and the beginning of what most people mean when they talk about 'evolution'.

Later still a big development occurred as such multicellular groupings began to reproduce so there there were then (larger) multicellular organisms with different gene sets. This marked a huge change and the beginning of what most people mean when they talk about 'evolution'. DNA mutations are random changes that occur by chance, such as errors during DNA replication or due to external factors like radiation. Natural selection then "selects" the mutations that help organisms survive and reproduce, while those that are detrimental are eliminated. This process makes evolution non-random, as it results in improvements in survival. However, evolution itself lacks any inherent purpose—it is simply a process. The concept of "evolution" has evolved over time. While the fundamental process remains unchanged, it now encompasses more than just genetic alterations. However, even with the notion of only being encompassed by genes, single-celled organisms eventually evolved into more complex life forms, which challenges the conventional idea that evolution is purely unintentional, as this progression suggests an increase in complexity. I digress a bit here. Things become even more fascinating—and possibly intentional—when we consider culture. Traditional evolutionary theory focuses on genetic mutations and natural selection, but organisms such as humans also shape their environment through cultural practices, which in turn influence evolution. By altering the very environment in which natural selection occurs, more advanced organisms, especially humans, take a significant step in the evolutionary process. Again, more advanced organisms can intentionally modify their surroundings, creating feedback loops that impact evolutionary outcomes. For example, human language is shaped both by biological and cultural evolution. Cultural traits such as intelligence or cooperation can influence genetic selection, making these traits more prevalent in future generations. When we consider culture and human behavior alongside biology, evolution becomes a more dynamic and interactive process. While natural selection remains an important factor, cultural actions and practices can modify or amplify its effects, creating new environments and challenges. In this perspective, random mutations and environmental factors are not the sole drivers of evolution, but the whole process is also affected by the changes humans and other organisms make to the world. Evolution becomes a more complex and multi-dimensional process, with culture playing a crucial role in shaping one’s future.

Without critiquing your criticism of me, I simplified my argument to highlight that there may be intention behind the evolutionary process, rather than it being purely mechanical.
