Introgressive hybridization among domestic dogs and wolves has been documented, with specific chromosomal areas favoring excess hybrid origin. FRD introgression in wolves is under genetic drift's major influence, and there are just a few positively selected genes associated with behavior and brain function. This introgression has been successful in realizing adaptive advantages in the form of increased genetic diversity and improved survival mechanisms (Pilot et al., 2021). Also, past hybridization has provided high-altitude adaptation to certain wolf populations such as the Tibetan wolves and Himalayan wolves through the introduction of beneficial genetic variants from a reclusive wolf-like lineage (Wang et al., 2020). These presents showcase the complexity of wolf evolution and their ability to adapt to a variety of environmental stresses. 5 Behavioral Genetics of Coyotes 5.1 Adaptability and ecological flexibility Coyotes (Canis latrans) are ecologically flexible and highly adaptable and are able to sustain themselves in a broad variety of environments, including urban environments. This flexibility is, in part, made possible by cognitive flexibility that allows them to learn to cope with rapid and incremental change in their surroundings. Coyotes have been reported to track alterations in spatial reward contingencies and adjust their behavior based on such alterations, showing extreme cognitive flexibility (Van Bourg et al., 2022). This ability to adapt to novel and altering conditions is one of the reasons for their success in urban areas. 5.2 Genetic underpinnings of boldness and problem-solving The coyote's boldness and problem-solving ability are genetically regulated. Urban coyotes tend to be more bolder and inquisitive than rural coyotes, a trait which has most likely been adapted due to the heterogenous selective pressures of the cities (Breck et al., 2019; Brooks et al., 2020). For instance, a study of a melanistic coyote in Atlanta revealed that although he was very bold in his action, he did not possess any hypersociability mutations, and thus boldness in coyotes can be influenced by other genes as well (Mowry et al., 2021). Additionally, possession of dog alleles in the genomes of some coyotes, acquired via hybridization, might also decide their exploratory and bold behavior. 5.3 Behavioral traits facilitating urban coexistence Coyotes have developed certain behavioral traits that help them survive in human-dominated environments. Boldness and reduced wariness of human items are salient traits that help urban coyotes travel and take advantage of human-modified landscapes effectively (Brooks et al., 2020). These traits are a product of both learning and evolution as human-adapted coyotes that are likely to explore into novel situations are at an advantage regarding survival (Breck et al., 2019). Furthermore, cognitive flexibility enables the coyotes to accommodate the intricate and changing urban environment, thus better positioned to share their living space with humans (Van Bourg et al., 2022). 6 Behavioral Genetics of Dogs 6.1 Selective breeding and its influence on behavior Selective breeding has played a crucial role in determining the behavioral traits of domestic dogs. Dogs were previously bred for function, such as hunting, herding, and guarding, and it led to establishing special behavior in the diverse breeds (Morrill et al., 2022; Dutrow et al., 2022). For instance, herding breeds possess behavior that is a domesticated form of predation, in which the urge to kill has been removed (Shan et al., 2021). Similarly, there has also been massive neuroanatomical variation across breeds, in line with specialized function (Hecht et al., 2019). But newer breeds that came into the market are being selected increasingly in terms of looks rather than useful behaviors, and that provides a connection between behavior and genetics (Figure 2) (Morrill et al., 2022). 6.2 Genetic markers associated with trainability, social bonding, and temperament A few genetic markers have been found for large behavioral traits in dogs in studies. For example, genome-wide association studies (GWAS) identified several loci with trainability, social bonding, and temperament.
