Dolphins and most small whales have a ‘sound lens’ on their forehead—the ‘melon’. This helps them to locate objects by echolocation. This sophisticated ‘lens’ bends sound by a very particular arrangements of lipids which are unique to this sound lens, each lipid requiring complex chemical processes and enzymes to produce. This ‘melon’ could not have evolved slowly over time; without all of these enzymes and lipids in the right sequence and shape, the echolocation would not work. 1

- Sarfati, 1999, p. 70: “One amazing adaption of most echo-locating dolphins and small whales is the ‘melon,’ a fatty protrusion on the forehead. This ‘melon’ is actually a sound lens — a sophisticated structure designed to focus the emitted sound waves into a beam which the dolphin can direct where it likes. This sound lens depends on the fact that different lipids (fatty compounds) bend the ultrasonic sound waves traveling through them in different ways. The different lipids have to be arranged in the right shape and sequence in order to focus the returning sound echoes. Each separate lipid is unique and different from normal blubber lipids, and is made by a complicated chemical process, requiring a number of different enzymes.
For such an organ to have evolved, random mutations must have formed the right enzymes to make the lipids to be deposited in the right places and shape. A gradual step-by-step evolution of the organ is not feasible, because until the lipids were fully formed and at least partly in the right place and shape, they would have been of no use. Therefore, natural selection would not have favored incomplete intermediate forms.” ↩
