every particale or species tends to be more and more evolved
Just after big bang there was nothing but energy spreading in every possible direction. This energy after cooling to certain limit forms first mass of the universe that is the smallest atomic structure ie the electrons these electrons attain the heat released during big bang and started moving at very high speed forming glowing disk around a black hole at there center . this electon disk forms is the base for every matter this electron forms the first of element ie hydrogen. From the its the property of every atom to evolve into more complex and evolved atom like hydrogen under right temperature and pressure forms helium and soo on After all the element essential for formation of stars planets and galaxies this evolution taken a diffent way of evolving some element combine together in fider quantity at right condition to form life on this planet the first of life itself a micro-organism. then the story of evolution of life has started and we can see soo many variet of plants and orga
