Some animals exhibit intelligence in a way we have never thought of! Yes, this is a cautious suggestion by a line of research being recently reported. And they are the ‘chimpanzees’.
They have surprised a team of researchers by making wooden spears for hunting! This is the first known and surprising example of weapon-making by a ‘nonhuman’. Western scrub jays have shown future planning in their caching behavior for food, and not their instinctive actions.
The ravens have demonstrated logical thinking by solving a puzzle of food-retrieval. Revelations like these are helping scientists make the crucial distinction between -
Genetically hard-wired behavior or trial-and-error learning and “intelligent” thinking.
Until this finding, scientists knew that chimps can make tools, including stone tools only. But, now they are found to be making weapons, revealing the fact that the more closely one study the chimps, the more humanlike traits are displayed.
