I dont understand

from the site:

Cells act like magnets, for they are magnets them selves. The earliest type of animals are all worm like, long and straight animals. Because a cell has North and South pole just like a magnet, it attracts to aother cell's North or South pole. With this attraction, a group of cells form into a single straight line. The earliest animals were formed that way. If magnetic energy is further applied to animal body, in the correct polarity, it will make the animal body more stronger and denser
