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.
Lateral hypothalamus is to Hunger as the ventromedial hypothalamus is to eating.
In animal when the lateral hypothalamus is destroyed it result to loss of hunger and when ventromedial hypothalamus is destroyed result to overeating.lateral hypothalamus control hunger while Ventromedial hypothalamus is involved in feeding,fear and sex activities
