Palm trees have no relation to palmistry as the palm of a hand has. Following the discovery that Trisomy 21 was the primary cause of Down Syndrome
, which includes the presence of distinctive palmar ridged skin signs (unusual patterns), the science of Dermatoglyphics
(the study of glyphs or dermal ridges on the volar skin of palms, soles and digital tips) gained impetus.
Currently, there is a revival of interest in Dermatoglyphics mainly because the laborious manual analyses of past years is now automated by advanced imaging analysis programs. Furthermore, Dermatoglyphic features are good markers of symmetry. A asymmetry may be an indicator of negative environmental or genetic impacts on embryonic development.
