Explanation:
All Animals have EVERY right to a good quality of life! It is humans with a typical human arrogance that decide who lives, who dies, who is food and who is not and how they will live and be killed. We even have Animal Protection laws for dogs, cats and “pets” and farm animals are treated like dirt, having very few protections! If you did to your dog what you do to pigs you would go to jail! Discrimination and arrogance taken to the nth degree! Since humans subject Animals to the existence humans choose and nobody ever asked a cow, a pig, a hen or any other animal how they want to live their life I think it can qualify as “Slavery”.
Answer:
The duplication of a cluster of four Hox genes is equally likely as the duplication of a single Hox gene.
Explanation:
This comes from the definition of the parsimony principle, which is the action of choosing the simplest scientific explanation fitting the given evidence, meaning that all other elements are equal when evaluating the hypothesis. In biology the best hypothesis is the one that requires the fewest evolutionary changes.
Since three independent duplications of an individual Hox gene is in evolutionary terms, more complex than a single duplication or a cluster, then that hypothesis would be the most parsimonious.
