49:5.11

Normal adjustments to planetary conditions follow the general physical patterns previously considered. The worlds of the nonbreathers typify the radical or extreme adjustment, but other types are also included in this group. Experimental worlds are usually ideally adapted to the typical life forms, and on these decimal planets the Life Carriers attempt to produce beneficial variations in the standard life designs. Since your world is an experimental planet, it differs markedly from its sister spheres in Satania; many forms of life have appeared on Urantia that are not found elsewhere; likewise are many common species absent from your planet.
