A.Word.A.Daywith Anu Garg
1. The ridge patterns of skin on the inner surface of the hands and feet.
2. The scientific study of these skin patterns.
ETYMOLOGY:The term was coined in 1926 by Dr Harold Cummins (1893-1976), from Greek dermato- (skin) + glyphein (to carve). Ultimately from the Indo-European root gleubh- (to tear apart) that is also the source of cleve, glyph, clever, and clove (garlic). And that's also where we get cleavage, cleft palate, and cloven hooves.
USAGE:"What makes dermatoglyphics important as markers for disease and traits is the fact that they develop at specific times in the foetus. Fingerprints, for example, begin to form at around the 13th week and are completed around week 18 -- the same time that critical growth in the brain is taking place."
