NATURAL MYSTERIES Advances in science and technology may have helped us solve many natural mysteries, but there are some that still purzie scientists. Keep reading tor three natural events that science has yet to fun explain Animal Migration Migration has fascinated humans for centuries Ancient civilizations puzzled over why large numbers of animals would disappear and reappear at certain times af the year Many animal species make annual journeys to faraway lands, usually to find food, warmer weather, or places breed Distances traveled are often vast. For example, the monarch butterfly ties between 2.000 to 4.500 kilometers for more) from and Canada to torests in central Mexico There, they hibernate and produce the next generation of butterflies that will make the trip back How an insect weighing as much as a paper clip can complete such long journey is one thing what's more mystifying is how these animals even manage to get to their locations, especially when they've never been taught to do so The biologist Rupert Sheldrake noted, Baby green turtles that have hatched on the beaches of Ascension lsiarid. the middle of the Atlantic, find their way across the ocean to the ancestral feeding grounds off the Brazilian coast. Years later, when the time comes for them to lay their eggs, they then make their way back to Ascension lsland, onl miles across and over 1,400 mdes away, with no landin between The main theory is that these migrating animals navigate using the sun, moon, and stars, a magn sense, or the sense of smell. But heavenly bodies are not always and the Earth's magnetic field is known be very would an anni smell its destination from such a distance? It seems many of these creatures just know their way by sheer intuition.
