ORGANIC SYSTEMS AND EVOLUTION strikes against the top. There happens to be on the forehead of these dolphins a large fat-packed, oval shaped organ called a melon. The compressed air, when it strikes against the melon, activates it to initiate a strange incomprehensible phenomenon. That lump of fat immediately turns into a fantastic sonar station. It works like a sound lens that emits a sonic searchlight which can move ahead uninterrupted by the turbid waters or mud. . The dolphin can emit 700 such sonar signals per second which are echoed back when they strike against any solid object. The echoes are perfectly calculated by the dolphin's brain to indicate to it the exact distance between the dolphin and the object, and also the precise nature of that obstruction. It can perceive a small metallic object at some distance and know exactly whether it is filled or empty. It can distinguish between living and non-living objects. The dolphin employs the same device in the open seas to detect fish even miles ahead. Aided by the same sonar device, it rapidly homes in on them constantly calculating how close it has reached the shoal before it begins to rapidly swallow them up, one after the other. 6. Could natural selection create this complex sonar system with an exactly corresponding receptive apparatus in the brain which could precisely decipher the echoes? Can any naturalist create a similar bulk of fat to produce a welldirected sonar beam? Whatever modern technology he may employ, let him try his hand at producing even a single sonar wave from such a fatty bulk. Yet a dolphin's melon can somehow produce 700 such waves per second. . The great brainwave of Darwin, which the naturalists believed solved the riddle of life, could only produce three dead principles: struggle for existence, survival of the fittest and natural selection to carve and modulate life. The naturalists prefer to forget that all these three principles are 506
