From similarity and differences of morphological, biochemical, cellular characteristics, biologist have constructed 'phylogenetic (evolutionary) trees' (who is most closely related to who, analogous to a family tree)
In the United States, lightning routinely kills more people each year than tornadoes or hurricanes. Tornadoes, hail, and wind gusts get the most attention, but only lightning can strike outside the storm itself. Lightning is the first thunderstorm hazard to arrive and the last to leave.
Lightning is another fatal aspect of severe weather, totaling roughly 35 deaths per year, according to NOAA. Lightning can strike the ground up to ten miles away from where the storm cloud might be. Sometimes âbolts from the blueâ occur when there are blue skies as far as the eye can see, but a bit of rogue electricity touches down.
