According to researchers, the choice of one part or another has to do with brain use and can be a more complex process than expected. At first they thought that when using the veil that was right to make the tools was also right, but now they have seen that it does not have to be so. Because different muscles are used in the manufacture and management of the tools, the parts of the brain that are activated are also different, and depending on this are the right and left knees.

The research was carried out with the candles of New Caledonia. In fact, these candles ( Corvus moneduloides) are very competent in the manufacture of hook shaped instruments, and even more able to use these hooks to extract insects from the holes.
