65:6.4 One of the most serviceable and [[complex]] [[episodes]] in the [[evolution]] of the higher [[types]] of [[animals]] consisted in the [[development]] of the [[ability]] of the [http://en.wikipedia.org/wiki/Iron iron] in the circulating [http://en.wikipedia.org/wiki/Blood_cells blood cells] to [[perform]] in the double role of [http://en.wikipedia.org/wiki/Oxygen oxygen] carrier and [http://en.wikipedia.org/wiki/Carbon_dioxide carbon dioxide] remover. And this [[performance]] of the [http://en.wikipedia.org/wiki/Red_blood_cells red blood cells] [[illustrates]] how [[evolving]] [[organisms]] are able to [[adapt]] their [[functions]] to varying or changing [[environment]]. The higher [[animals]], including [[man]], oxygenate their tissues by the [[action]] of the [http://en.wikipedia.org/wiki/Iron iron] of the [http://en.wikipedia.org/wiki/Red_blood_cells red blood cells], which carries [http://en.wikipedia.org/wiki/Oxygen oxygen] to the living [[cells]] and just as [[efficiently]] removes the [http://en.wikipedia.org/wiki/Carbon_dioxide carbon dioxide]. But other metals can be made to serve the same [[purpose]]. The [http://en.wikipedia.org/wiki/Cuttlefish cuttlefish] employs [http://en.wikipedia.org/wiki/Copper copper] for this [[function]], and the [http://en.wikipedia.org/wiki/Sea_squirt sea squirt] utilizes [http://en.wikipedia.org/wiki/Vanadium vanadium].

65:6.5 The [[continuation]] of such [[biologic]] [[adjustments]] is [[illustrated]] by the [[evolution]] of [http://en.wikipedia.org/wiki/Teeth teeth] in the higher [[Urantia]] [[mammals]]; these [[attained]] to thirty-six in [[man]]'s remote [[ancestors]], and then began an [[adaptative]] readjustment toward thirty-two in the [http://nordan.daynal.org/wiki/index.php?title=Paper_62 dawn man] and his near relatives. Now the [[human]] [[species]] is slowly gravitating toward twenty-eight. The [[process]] of [[evolution]] is still [[actively]] and adaptatively in [[progress]] on this [[planet]].

65:6.6 But many seemingly [[mysterious]] [[adjustments]] of living [[organisms]] are [[purely]] [[chemical]], wholly [[physical]]. At any [[moment]] of [[time]], in the [http://en.wikipedia.org/wiki/Blood blood stream] of any [[human being]] there exists the [[possibility]] of upward of 15,000,000 [[chemical]] [[reactions]] between the [http://en.wikipedia.org/wiki/Hormone hormone] output of a dozen ductless glands.

65:6.10 The [[physical]] [[brain]] with its [[associated]] [[nervous system]] [[possesses]] [[innate]] [[capacity]] for [[response]] to [[mind]] [[ministry]] just as the [[developing]] [[mind]] of a [[personality]] [[possesses]] a certain [[innate]] [[capacity]] for [[spirit]] [[receptivity]] and therefore contains the [[potentials]] of [[spiritual]] [[progress]] and [[attainment]]. [[Intellectual]], [[social]], [[moral]], and [[spiritual]] [[evolution]] are dependent on the [[mind]] [[ministry]] of the [[seven adjutant spirits]] and their superphysical [[associates]].
