We concluded that a corn rock most likely forms when small blobs of molten lava splash down over an ear. A falling blob of basalt lava would have a low enough viscosity to envelope an ear before the molten hardens to solid rock...

Obviously, it would not be safe for humans to carry ears of corn into the fallout zone of a towering lava fountain. A safe setting, however, would be at what geologists call an hornito (means "little oven" in Spanish). An hornito is essentially a miniature volcano that spews molten blobs of melt that fall back to Earth and accumulate into a welded-together chimney-like stack as they solidify and cool...

So, early Native Americans living near the present site of Sunset Crater Volcano witnessed an eruption that at some stage could be safely approached to place ears of corn at the base of an active hornito.

To test that hypothesis, co-authors Rodger Kram and James Wilson spent the summer of 2020 training until they could haul a heavy log some 15 miles using tumplines. "Some people baked sourdough bread during COVID," said Kram, an emeritus professor of integrative physiology at the University of Colorado at Boulder. "Instead, we carried sand and heavy logs around using our heads."

Besides supplanting radio and radar, the super-brain will do away with electronic computing devices, because there will be no problem too complex for it to solve. It will be a storehouse of facts and memory as well as a powerhouse for constructive thinking.

The gradual merging of man's two eyes into one may come about through the process of evolution, according to the predictions which W.E. Bailey makes in the Scientific American.

"Man's field of view," writes Mr. Bailey, "will become smaller and smaller. This, because his need of a wide field is growing less and less. This I say with full realization that we live in an age of automobiles, and that these vehicles render desirable a wide field of view. The automobile is probably a very transitory phenomenon. I even believe that, in the course of countless ages, the two human eyes will come closer together, the bridge of the nose will further diminish and sink (just as the animal snout, in man's line of descent, has been doing for vast aeons of time) and, finally, man's two eyes will again become one—just one large, central, cyclopean eye.

"It is likely that the merely servient (left) eye will shrink away (as the pineal eye has already done) so that the right eye will become the cyclopean. Certain it is that the left eye, even today, is being used less and less continually. Man's binocular and stereoscopic visions are being destroyed. That is the price he pays for his speech center.

"The great cyclopean eye, however, will regain stereoscopic vision by developing two maculae in the one eye, just in the fashion in which many birds have stereoscopic vision in each eye now. Although the field of view will then be narrower than now, the eye will probably be microscopic and telescopic; it will be exceedingly acute for colors, for motion, and for form; and finally, most important of all, it will probably be able to perceive as light many forms of energy which now produce in human eyes no sort or kind of perception.

"Because of the development of a speech center in man, there has come about what is called dominancy and serviency in human eyes, a phenomenon not found in other mammals. This means that, in the human, the brain does most of the seeing through one eye, even when both eyes are open. Dr. Thomas Hall Shastid, ophthalmologist of St. Luke's Hospital, Duluth, has found that from 95 to 100 per cent of the detail of any object comes through the right eye if the person be right-handed; while if the person be left-handed the left eye as a rule, but not always, takes up the major part of the detail. This condition, which he has been unable to observe in any other animal, may eventually result in consequences of vast importance to humanity."

Marshall’s version of the future human being is a sleek-featured, diminutive person, much like the creatures seen in many science-fiction movies.

Today’s diet of soft, processed foods will take its toll on the human jaw and teeth, which have been diminishing since prehistoric days when our ancestors used their mouths as weapons, in addition to making tough foods palatable, Marshall says.

“Nature has a wonderful way of providing for her needs. Whatever she doesn’t need, she gets rid of,” Marshall says. “Things develop according to function. If you use something, it develops. If you don’t, it disappears.”

Since people today do not use their teeth the way they once did, future people probably will have much smaller, and fewer teeth, Marshall’s prediction indicates. They will be practically hairless and their jaws will diminish as they have for thousands of years, he says. The chin and nose will be more prominent.

The changes Marshall foresees also will give future people a wider range of facial expressions…

He has turned his office into a museum on the development of the human skull, tracing its evolutionary and embryonic progress in exhibits and photographs… One of the exhibits in his personal museum is a line of busts depicting the evolutionary changes in the human skull from prehistoric times to his vision of what people will look like 2 million years into the future…

But even with the possibility of scientific advances influencing evolution, Marshall expresses confidence that his projections cannot be disputed.
“No one is going to disprove me,” he says. “They won’t be around.”
