Over time, the evolution of several species has drastically changed and diversified. Thousands of years ago, most species did not have the wide variety of breeds and appearances that occur today. Specifically, canines evolved from one single animal into the 150 or more modern breeds that animal scientists recognize. By using historical evidence, DNA collections, and anatomical evolution records, scientists can interpret this information to form a modern analysis on canine evolution, and utilize this research to hypothesize what further manipulations may occur in the future. Scientists have discovered many pieces of evidence that provide information on the location and time period of the domestication of canines. One German researcher discovered …show more content…

Scientists re-created a canidae family tree by comparing DNA from ancient dogs, modern purebreds, mutts, and wolves (Becker 2017; Richard 2006). This lineage provided information that wolves and domestic dogs split apart around 20,000-40,000 years ago, around the time researchers have predicted domestication to occur. Also, populations of Eastern and Western dog breeds split around 17,000-24,000 years ago, which shows the reason behind the drastic differences of each area’s respective dog breeds. Laurent Frantz sequenced the genome from a 5,000 year old dog and compared the results to the nuclear DNA of 605 modern dogs. He discovered similar findings, where Asian and European dogs experiences a split around 14,000 years ago (Grimm 2016). Therefore, similar data shows that while domestication continues to create arguments on the time period, many researchers agree that Eastern and Western canines underwent a divide between 14,000 and 20,000 years ago (Terlach …show more content…

Taking cues from a human’s behavior has shown that “selection pressure during domestication affected dogs’ skills in behavior” (Kelly 2014). After the domestication process, canines began to synchronize with their owners. Researchers have discovered many similarities between the evolving social and behavioral patterns of humans and dogs. Through convergent evolution, humans underwent a form of self-domestication leading to greater social abilities, thereby cognately evolving with canines that also went through the same process (Hare 2005). The superiority of social performance of canines with humans proves that convergent evolution occurred because of the development of strong bonds between them over several thousand years. Moreover, dogs possess the ability to learn social cues, and studies have proven that many canines are more “adept in the delivery and perception of nonverbal cues by means of body language than humans” (Richard 2006). Many of these behaviors were learned during the early domestication period, when canines increased their vocalizations towards when alerting them of danger and other
