Introduction
Animal cognition encompasses the mental capabilities of animals on how they process information and behave. Although wolves and dogs share a common ancestor, their cognitive traits offer unique abilities in problem-solving and social behaviours. Loog et al. (2020) state that dogs and wolves belong to a relatively recent evolutionary ancestry with a common ancestor approximately 15,000-40,000 years ago. Cognitive differences between According to Pettersson et al. (2023) wolves are highly adjusted to the requirements of an existence in nature, survival being contingent upon complex social relations within packs and on independent problem-solving abilities. On the other hand,Miklósi, Abdai, and Temesi (2021) provided thatdogs have evolved with humans, developing peculiarly other social and communicative abilities that encourage cooperation with people.Therefore, dogs and wolves offer a unique opportunity to study how domestication might alter cognitive ability in animals.
This primer review hypothesises that the cognitive differences in dogs and wolves are primarily driven by domestication or due to pressures of environmental factors. This primer review attempts to explore the differences in cognition found between wolves and dogs to establish whether such differences are due to practices of domestication or the impact of environmental and evolutionary pressures.

Domestication and Cognitive Adaptations
An important characteristic of dog cognitive adaptation lies in their ability to recognise human social signals, seemingly superior compared with those of wolves. The findings byBenz-Schwarzburg, Monsó, and Huber (2020) show that dogs easily follow the pointing actions of human beings, even when other species, such as wolves, fail to understand these actions. The mentioned study determines that dogs are intriguingly good at understanding human gestures, such as point-following, while often being very fast to track gaze or read facial expressions, a capacity that is relatively underdeveloped in wolves. This ability in dogs has been hypothesised to have resulted from thousands of years of co-evolution with humans during which time dogs became familiar with human behaviours as an important survival mechanism.Similarly, Gee et al. (2021) state that dogs possess an innate understanding of human intentions which is referred to as a cognitive capability.Furthermore,Pérez Fraga et al. (2021) found that wolves did not overcome their difficulties with task-based events that required human-directed cues, thereby indicating that experience alone is insufficient to develop this aspect of learning ability.
According to Johnson-Ulrich, Johnson-Ulrich, and Holekamp (2022),wolves stay longer and use more problem-solving on a puzzle than dogs. The mentioned study determines that this propensity for early rejection is a kind of cognitive trade-off that defines dog’s extreme cooperation with humans but perhaps have become less adept at independent problem-solving compared to their wild relatives. On the other hand, Correia-Caeiro, Guo, and Mills (2021) explorethe cognitive adaptation of dogs in their capacity to read human emotions and behave with empathetic-like tendencies. Dogs can easily recognise human emotional cues in facial expressions and voice tone and often reflect the owner's emotional state. On the other hand, Jürgens et al. (2023) state that empathetic capacity is less developed in wolves, so perhaps dogs are cognitively more attuned and have thus acquired specialised cognitive mechanisms. This ability to respond to human emotions may be an evolutionary adaption to living within human social systems, whereby an ability to be responsive to human moods and reactions would necessarily be key to maintaining positive relationships.
Environmental and Evolutionary Pressures on Cognitive Traits
Where domestication undoubtedly impacted the cognition of dogs, it provided much of the credit to environmental and evolutionary factors that placed such selective pressure on dog evolution. According to Salomons et al. (2021), wolves have developed cognitive skills that would help them survive in complex social structures, often harsh and competitive conditions. Such pressures would have required acute problem-solving skills, as well as social cooperation strategies for hunting and resource sharing. This would all work together to create a set of cognitive traits optimised for life in the wild. Moreover, Range andMarshall-Pescini (2022) state that cognitive differences between wolves and dogs need not be based solely on domestication butthe environment also contributes to those differences. The mentioned study findings determined that dogs have become dependent on humans for help and resources, on the other hand, a wolf is highly self-dependent. Such skills in wolves are environmental cognitive adaptations rather than due to their lack of domestication.
Additionally,Benson-Amram, Griebling, and Sluka (2023) state that ecological factors have shaped dogs' intelligence in diverse ways depending on particular niches and roles within human societies. Early dogs likely lived at the periphery of human communities, scavenging from their waste, which would have served as selective agents that favoured tolerance of and reduced aggression toward humans. These early environmental conditions might have predisposed them to further cognitive adaptations like sensitivity towards human behaviour and responsiveness to social cues which later came to be reinforced through selective breeding.The communication skills of wolves and dogs may likely be a result of evolutionary forces such as predation, social competition, and scarcity of resources. Berghänel et al. (2022) reported that the survival of wolves depends on highly evolved observational skills to detect both threats and prey. The findings of the mentioned study determined that the same skills have been inherited by some domesticated breeds of dogs because of the original working roles they were assigned in the wild. Such traits show the impact of natural selection on these animals' cognitive powers and are more than simple domestication.
Overall, while selective pressure by domestication has modified certain cognitive abilities concerning human needs, environmental and evolutionary pressures have played a role in the earlier evolutionary development of basic cognitive abilities shared by both species. Thus, this combination demonstrates how intricate the impact of human-driven selection is combined with natural evolutionary forces into the range of cognitive diversity represented among the mentioned species. This sheds light on how the different cognitive features may arise from a role in serving direct human purposes, as well as from other ecological requirements.
Discussions
It can be discussed that cognitive differences between wolves and dogs place severe challenges on the role that domestication played in shaping dogs' abilities-particularly in the areas of human-centred social skills. In summary, while wolves demonstrate some level of cognitive complexity, the studies do show that dogs have evolved with unique abilities for interpreting and responding to human behaviour-mostly from selective pressures of domestication rather than from any innate cognitive advantages not tied to human influences.
The review shows that it is essentially this ability to track many human social gestures, such as pointing and gaze-following, which forms the basis for the dog's differences in adaptation from those of wolves. According to Benz-Schwarzburg, Monsó, and Huber (2020), dogs outperform wolves in interpreting many human gestures and expressions. This suggests that domestication has fostered within the dog a capacity for processing social information that is extremely well complimented to humans' expectations, a feature that would be useful in a home setting but entirely unnecessary in the wild. It can be discussed that Pérez Fraga et al. (2021) confirm the same by stating that wolves seem unable to cope with similar challenges involving human-directed cues, suggesting the skill might not emerge necessarily through exposure alone, but as a result of focused selection due to coexistence with humans over generations.
Moreover, according to Gee et al. (2021) and Correia-Caeiro, Guo, and Mills (2021), dogs are even more sensitive to human emotions and sympathy and are provoked by domestication. Unlike, the wolves, domesticated dogs have the capability of feeling and reflecting man's emotional states, an ability that is very important in their role as man's companions and companions in society. According to Jürgens et al. (2023), empathic behaviour is much less expressed in wolves, and may be inferred that dogs domesticated could have evolved specific mechanisms of cognition to bond with humans. Such adaptations, in turn, indicate the ways through which the domestication process could have provided a social-cognitive shift favouring the understanding and activity in line with human emotions.
While the wolves possess well-developed problem-solving abilities appropriate for their solitary life, the analogy suggests that dogs traded off cognitively because their strong reliance on human society has reduced their reliance on self-sufficiency in problem-solving. According to Johnson-Ulrich et al. (2022), studies concluded that, unlike wolves, dogs tend to require more help solicitation from humans when experiencing problem-solving and do not hold on persistently. This alone explains why this argument for the natural selection of dogs to become more allies of man, even if at the cost of their free independent problem-solving strategy is tenable.
It can be discussed that although wolves have developed cognitive skills that serve them well in natural environments, work by Range and Marshall-Pescini (2022) and Benson-Amram, Griebling, and Sluka (2023) indicates that these adaptations exist primarily to promote self-sufficiency and social cooperation of wolves with one another, rather than for skills that would benefit other humans. So although ecological and evolutionary factors undoubtedly inform fundamental cognitive features, domestication has directed these features in dogs to behaviours and skills that are highly sensitive to human social factors.
While these overall cognitive abilities had to be largely shaped by evolutionary and environmental pressures among the ancestors, domestication is the main force behind the cognitive adaptations unique to dogs as seen today. Selective breeding and thousands of years of interaction by humans have driven the development of traits like social sensitivity and empathy that are closest to human needs. Therefore, while wolves and dogs do share some ancestral cognitive traits, domestication is what makes these abilities refined and specialized in dogs to thrive in a human-centred environment.
Conclusion
In summary, evolutionary and environmental pressures have certainly played a role in the cognitive commonalities between wolves and dogs, but domestication is the primary feature that is highlighted in thisreview as a process that led uniquely to the social-cognitive adaptations of their counterparts. Within the contemporary timesof co-evolution with humans, dogs eventually developed superior skills in understanding and appropriately responding to cues of human emotion and intent than any wolf. The research indicates empathy and human-directed problem-solving behaviours are much more developed in dogs than wolves, indicating selective pressures tied to their roles within human society. Such cognitive traits have been honed for home life, but domesticated canine metacognition comes at the price of favouring cooperative and communicative abilities over independent survival skills required for wolves. Therefore, it is domestication more than any other that has shaped the dog's mind to be remarkably familiarwith human social contexts.
