<em>Comparisons of items eaten for food</em>
Explanation:
If we compare the diet intake of different organisms we will not be able to predict whether the organism has an evolutionary history or not. Hence, comparisons of items eaten for food is the LEAST useful technique to explore evolutionary history among organisms.
Other options mentioned will however be beneficial in understanding the evolutionary history among organisms. For example, analysis of DNA strands of different animal species will tell us the similarities and differences in the DNA strand. As a result, we will e able to predict whether they have evolutionary history or not.
True rib : the first seven ribs attach to the sternum (the breast bone) in the front and are known as true ribs (or sternal ribs)
