562 But on some worlds, for ages they continue to fly even after they have become land-type beings.

It is both amazing and amusing to observe the early civilization of a primitive race of human beings taking shape, in one case, in the air and treetops and, in another, midst the shallow waters of sheltered tropic basins, as well as on the bottom, sides, and shores of these marine gardens of the dawn races of such extraordinary spheres. Even on Urantia there was a long age during which primitive man preserved himself and advanced his primitive civilization by living for the most part in the treetops as did his earlier arboreal ancestors. And on Urantia you still have a group of diminutive mammals (the bat family) that are air navigators, and your seals and whales, of marine habitat, are also of the mammalian order.

In Satania, of the elemental types, seven per cent are water, ten per cent air. seventy per cent land, and thirteen per cent combined land-and-air types. But these modifications of early intelligent creatures are neither human fishes nor human birds. They are of the human and prehuman types, neither superfishes nor glorified birds but distinctly mortal.

3. The gravity types. By modification of creative design, intelligent beings are so constructed that they can freely function on spheres both smaller and larger than Urantia, thus being, in measure, accommodated to the gravity of those planets which are not of ideal size and density.

The various planetary types of mortals vary in height, the average in Nebadon being a trifle under seven feet. Some of the larger worlds are peopled with beings who are only about two and one-half feet in height. Mortal stature ranges from here on up through the average heights on the average-sized planets to around ten feet on the smaller inhabited spheres. In Satania there is only one race under four feet in height. Twenty per cent of the Satania inhabited worlds are peopled with mortals of the modified gravity types occupying the larger and the smaller planets.

4. The temperature types. It is possible to create living beings who can withstand temperatures both much higher and much lower than the life range of the Urantia races. There are five distinct orders of beings as they are classified with reference to heat-regulating mechanisms. In this scale the Urantia races are number three. Thirty per cent of Satania worlds are peopled with races of modified temperature types. Twelve per cent belong to the higher temperature ranges, eighteen per cent to the lower, as compared with Urantians, who function in the mid-temperature group.

5. The electric types. The electric, magnetic, and electronic behavior of the worlds varies greatly. There are ten designs of mortal life variously fashioned to withstand the differential energy of the spheres. These ten varieties also react in slightly different ways to the chemical rays of ordinary sunlight. But these slight physical variations in no way affect the intellectual or the spiritual life.

Of the electric groupings of mortal life, almost twenty-three per cent belong to class number four, the Urantia type of existence. These types are distributed as follows: number 1, one per cent; number 2, two per cent; number 3, five per cent; number 4, twenty-three per cent; number 5, twenty-seven per cent;
