"Sponges and fresh water polyps are primitive animal forms. If one crushes a living sponge or a fresh water polyp to mash, passes the mash through a fine filter and pours it back into the water, then soon flat things emerge which round themselves to spherical shapes and finally attain full growth as individuals with characteristic organs such as mouth, tentacles etc."
