Dutch Astronomer Christiaan Huygens correctly deduced the the ears of Saturn were a distinct ring, disconnected from the parent planet and slightly tilted as observed from the earth. From a terrestrial perspective the ears would periodically vanish because the angle of vision changed during Saturn's voyage around the sun.

Then he located the controlling genes. Because they were first found in white blood cells, the surface proteins are called human leukocyte antigens (HLA), though they exist in all tissues. Over 40 antigens have been identified...
