Natural Selection vs Artificial Selection in the Domestication of Dogs
Introduction
Background
In the introduction i will introduce and give background information for the overall topic of dog domestication and how natural selection and artificial selection plays a role. Talk about how dogs are descended from wolves.
Thesis: Both natural selection and artificial selection are known to play a role in the domestication of dogs from their ancestor the wolves, however artificial selection has played a bigger role in shaping the diverse breeds of dogs that are seen in our world today.
Body paragraph 1
In the first body paragraph i will discuss and define natural selection in wolves. How natural selection created the physical and behavioral characteristics of wolves and how it caused certain traits in wolves to be more adaptable to human environment.
Provide examples of those certain traits that came from natural selection and evidence to show the natural selection in early stages of domestication.
Body paragraph 2
In the second body paragraph i will talk about artificial selection and how humans can breed specific dogs to achieve the desired traits that benefit them. Talk about the different methods that were used to domesticate wolves.
Provide evidence/results and examples of how artificial selection has led to the breeding of different dogs with specialized traits and interbreeding to maintain those traits. For example, size, appearance, and hunting.
Discuss the experiments that were done to identify the dogs genes that are associated with behavioral and morphological traits. This indicates the different dogs that could have been artificially selected to be able to perfom these certain tasks.
Body paragraph 3
In the third body paragraph i will compare and contrast natural selection and artificial selection. I will talk about how natural selection is driven by environmental factors, while artificial selection is driven by human involvement. Also, I will discuss the importance of each process in the domestication of dogs.
In this paragraph i can compare and contrast the mechanisms of both selections in dog domestication and the interplay between them both.
Conclusion
In the conclusion i will discuss and summarize the key points that will be talked about in the paper and emphasize the importance of both selection process.
Talk about the future directions for research on dog domestication and discuss the roles of natural and artificial selection in shaping the diversity of dog breeds and our understanding of evolution. I can discuss the key challenges for the future, for example, the challenges of domestication research in genomic and geographical maps.
