Greek Period The early Greek philosophers for the most part looked on movement as the most essential characteristic of life, different schools advocating different material elements as the ultimate principle of life. Others compound it of all the elements, whilst some of the Pythagoreans explain it as a harmony -- foreshadowing modern mechanical theories.The enigma of life is still one of the two or three most difficult problems that face both scientist and philosopher, and notwithstanding the progress of knowledge during the past twenty-three hundred years we do not seem to have advanced appreciably beyond the position of Aristotle in regard to the main issue.

Left-handedness is more common in men than in women, and tests of fetuses (using ultrasound) show 92% sucking their right thumbs, a figure that mirrors prevalence in the adult population, writes Lalumière.What causes us to be left- or right-handed, however, is undecided.Here are the theories: This newer concept of developmental instability has spawned new studies, writes Lalumière.
