The human body should have a particular weight for a particular height i.e: the height and weight ratio must be in a specified proportion to each other. If the height and weight are in proper ratios to each other, then the bodily functions take place smoothly.
What is the âparol evidence ruleâ? The parol evidence rule states that, if an agreement between two parties is made in writing, the parties may not present evidence in court of any oral or implied agreement that contradicts what is written down.
The parsimony principle is basic to all science and tells us to choose the simplest scientific explanation that fits the evidence. In terms of tree-building, that means that, all other things being equal, the best hypothesis is the one that requires the fewest evolutionary changes.ypothesis 1 requires six evolutionary changes and Hypothesis 2 requires seven evolutionary changes, with a bony skeleton evolving independently, twice. Although both fit the available data, the parsimony principle says that Hypothesis 1 is better  since it does not hypothesize unnecessarily complicated changes.
