Homsians scientists made a test on a frog , they reported :
1- cut the frog arm and tell him to jump => it jumps .
2- cut the other arm and tell him to jump => it jumps .
3- cut the frog leg and tell him to jump => it jumps .
4- cut the last leg and tell him to jump => it does not jump .
That means :
The frog loses his hearing instincts if you cut his long parts !
