The action of leaping or dancing; in geology, the bouncing movement of particles carried by wind or water; in evolution, a sudden dramatic mutation.
From Latin 'saltatio' (dancing), from 'saltare' (to dance/leap). Sand grains DANCE across deserts, molecules LEAP between states, and evolution sometimes JUMPS instead of crawling.
Sand DANCES across the desert! Literally — geologists call the bouncing movement of sand grains 'saltation' because each grain leaps like a tiny ballet dancer! Even evolution sometimes JUMPS instead of inching along! ðŸœï¸ðŸ’ƒ
