Question :
Domestication encompasses a whole suite of genetic changes that arise as a species is bred to be friendlier and less aggressive. In dogs and domesticated foxes, for example, many changes are physical: smaller teeth and skulls, floppy ears, and shorter, curlier tails. Which of the following would strengthen the main argument in the paragraph the most?
1. There have been cases where some species have been domesticated without causing any change to the genetic structure.
2. Species with smaller teeth and skulls may not be friendly.
3. It was found out that domesticated species have developed very different physical traits than other undomesticated species from the same ancestor.
4. Domesticated species tend to have longer lifespan.
5. Domestication of animals is unethical as it tries to interfere with the natural process by moulding them in a way to benefit humans.
