Владислав Педдер – The Experience of the Tragic (страница 3)

A crucial development in this theory is the notion of multilevel selection. Selection can occur not only at the level of individual organisms but also at the level of genes, groups, and even species. In this context, evolution can be seen as a process in which not only the most adaptive individuals are selected, but also those genetic combinations that increase the chances of survival for populations or groups.

One example illustrating multilevel selection is the phenomenon of the emergence of organisms with identical traits – for instance, the “green beard effect.” Imagine a population of animals in which a group of individuals randomly develops a unique feature – a green beard. This concept, proposed by Richard Dawkins, illustrates how traits that are not individually advantageous may be preserved and spread through group selection. In this case, individuals with a “green beard” (a symbolic trait that distinguishes them from others) may not possess any clear survival advantage, but if such individuals form a group, their shared traits can foster cooperation and mutual support within that group, increasing the survival chances of its members. Thus, the trait may be beneficial at the group level, even if it brings no direct benefit to individuals. The green beard may be selected through group selection, wherein mutual cooperation or even “signaling” for interaction among individuals arises, thereby contributing to the survival of the entire community. In this way, group-level evolution may lead to the spread of such a trait if it promotes cooperation and social interactions that increase the survival prospects of the group as a whole.

Dawkins, in his theory, also accounts for the importance of altruism in evolution. He argues that individuals who act in the interest of the group may contribute to the preservation of their own genes, even if such behavior does not offer direct personal benefit. An individual may contribute to the survival of other members – such as relatives or members of their group – at the cost of personal risk. In this context, if an individual with a green beard helps other members of their group to survive, their actions may enhance the overall success of the group, and such traits will be maintained and reinforced at the group level.

Viewing evolution as a process that takes place at multiple levels allows for the inclusion not only of organisms but also of broader evolutionary units such as populations, ecosystems, and even species. For example, within multicellular organisms or communities of organisms with identical traits (for example, behaviors or physical characteristics), there is a probability that these traits will be preserved through altruistic behavior that contributes to the overall success of the group. However, such behavior is important not only for the survival of particular individuals but also for the dissemination of their genes at the level of the entire population.

One of the clearest examples of such a phenomenon is symbiosis – a close, mutually beneficial coexistence of different species. When two or more species cooperate with one another, their chances of survival increase, and their traits may be preserved and reinforced through evolutionary mechanisms. traits such as the green beard may, in the long term, spread not only at the level of individual organisms but also within more complex biological systems, contributing to the survival of the group as a whole.

Today, it is believed that selection takes place at several levels: at the genetic level, selection occurs at the level of individual genes. Genes that contribute to the successful survival and reproduction of their carriers become fixed in a population, being transmitted to subsequent generations. This form of selection focuses on how specific genetic variations can increase their frequency in a population due to their effects on the organism or on their copies in other organisms. At the individual level, selection acts on the level of organisms. Individuals possessing traits that increase their chances of survival and successful reproduction are able to transmit their genes to the next generation. This leads to the spread of beneficial adaptations within the population and the fixation of traits that increase individual fitness. Kin selection occurs through assistance to close relatives who carry similar genes. Altruistic behavior toward kin can increase the chances of spreading shared genes, even if it decreases the individual’s own chances of survival. Such selection explains the emergence of cooperative behavior in family groups and colonies. At the group level, selection occurs at the level of groups of organisms. Groups in which members cooperate and support one another may have an advantage over groups dominated by selfish behavior. Competition among such groups may lead to the selection of cooperative strategies that increase the overall success of the group. At the level of ecosystems or symbiotic communities, selection may take place at the level of entire ecosystems or communities composed of interrelated species. In such systems, stable interactions such as symbiosis, cooperation, and mutual support may contribute to the successful existence of all participants in the community. If an ecosystem or symbiotic community successfully copes with environmental changes and maintains its stability, this may promote the survival and dissemination of all species that comprise it. Although this level of selection remains contested, examples of coevolution show that complex communities can form through cooperative and mutually beneficial relations between different organisms.

Modern research supports the ideas of multilevel selection, showing how cooperation at the level of groups and communities may contribute to evolutionary success. It is important to emphasize that evolution, as a process, largely depends on random mutations, which may either help or harm the organism. However, the presence of directionality in evolution is not excluded. With each generation, species become more adapted to their environment, but this does not happen through predetermined aims or designs – it is the result of the interaction between random changes and existing ecological and social factors.

Evolution has no predefined goal or endpoint. What is important is that it is not aimed at the creation of perfect beings, but only at adaptation to the specific conditions in which an organism exists. In this sense, evolution is not so much development as a process of endless adaptations and changes.

3. The Emergence of Mind

The mind is one of the most complex achievements of evolution and has become a key factor in the success of many species, especially humans. In this section, we will examine how evolution led to the emergence of the mind, explore differences in the development of cognitive abilities in mammals and cephalopods, and analyze how the brain uses predictive coding and Bayesian approaches to process information.

The Emergence of Mind: Evolutionary Prerequisites

The evolution of the mind is a gradual process of the development of increasingly complex cognitive abilities, such as learning, memory, prediction, and self- reflection. The mind did not emerge suddenly; its appearance was the result of millions of years of adaptation to changing environmental conditions.

The most significant steps on the path to the mind include the development of sensory systems and memory, which enabled organisms to accumulate information about their surroundings and use it for survival. The emergence of associative learning provided the ability to link stimuli and responses, helping to anticipate dangers and opportunities. The development of spatial thinking allowed animals to represent their environment and plan their actions. Finally, social interaction within groups contributed to the formation of communication and the emergence of more complex behavioral strategies.

Over time, these elements have evolved into complex cognitive systems capable of abstract thinking, self-awareness, and future planning.

Differences in the Evolution of Mind

A compelling example of the evolution of mind can be found in mammals and cephalopod mollusks such as octopuses – two distinct evolutionary paths toward intelligence that demonstrate the multidimensional and branching nature of the evolutionary landscape of cognition. In addition to these, there are other independent trajectories, such as the social intelligence of insects – bees and ants – based on collective behavior, as well as the development of complex forms of communication and problem-solving in birds, such as crows and parrots. These different paths reflect the diversity of adaptations to environmental conditions and strategies for survival.

Mammals, including humans, developed their minds in the context of social interaction and group living, which facilitated the formation of complex social structures. Their cognitive abilities were oriented toward solving problems related to cooperation, competition, and social communication, leading to the emergence of social hierarchies, the capacity for empathy, the development of theory of mind – understanding the thoughts and intentions of others – as well as the origins of language and abstract thinking. The mammalian brain features a highly developed cerebral cortex, particularly the frontal lobes, which are responsible for planning, self-control, and decision-making. In addition, the brain is closely linked to the hypothalamus and the endocrine system, which regulates behavior hormonally in response to internal and external stimuli.
