What Happened to the Lost Race of Supermen?

Monday, January 4th, 2010

Discover Magazine has a very intriguing story: In 1913 two farmers uncovered a skull in South Africa that still has paleontologists scratching their heads. The so-called Boskop Man was first thought to be a distinct genus while some argued he’s a variation of anatomically modern humans.

What made Boskop Man unique and the the other similar skulls found like him is that his brain was much, much larger then ours in relation to ours. Based on what we can infer about brain size between species, his (and her) larger brains and neocortex suggest this ancient race of man was way smarter than us. How much smarter?

In a classroom with 35 big-headed, baby-faced Boskop kids, you would likely encounter five or six with IQ scores at the upper range of what has ever been recorded in human history. The Boskops coexisted with our Homo sapiens forebears. Just as we see the ancient Homo erectus as a savage primitive, Boskop may have viewed us in somewhat the same way.

Boskop Man is believed to have lived between 30,000 to 10,000 years ago. Why this super-genius vanished is a mystery. The Discover Magazine article postulates some interesting theories, but no concrete leads. One potential scenario is that he just blended in with the rest of us as a wise uncle:

At his new dig site, FitzSimons came across a remarkable piece of construction. The site had been at one time a communal living center, perhaps tens of thousands of years ago. There were many collected rocks, leftover bones, and some casually interred skeletons of normal-looking humans. But to one side of the site, in a clearing, was a single, carefully constructed tomb, built for a single occupant—perhaps the tomb of a leader or of a revered wise man. His remains had been positioned to face the rising sun. In repose, he appeared unremarkable in every regard…except for a giant skull.

Maybe they just leap-frogged us altogether?

Does Our Solar System Have 900 Planets?

Monday, January 4th, 2010

After the discovery of Neptune in 1846 astronomers began to wonder if there were other planets beyond its orbit. The discovery of Pluto (now not a planet) seemed to answer the question, but others wondered if even further out a larger earth-sized object could be waiting to be discovered.

Space.com has a fascinating claim made by a planetary scientist, Alan Stern at the Southwest Research Institute:

“When the solar system’s story is finally written, it’s much more likely that it will have closer to 900 planets rather than the nine that we grew up with.”

900 planets? How could that be possible? Anything Earth or Mars-sized in the Kuiper Belt beyond Neptune would be visible; but beyond the Kuiper Belt is the Oort Cloud:

Brown and Stern say that the Oort Cloud represents a more likely prospect for worlds the size of Mars or Earth. The Oort Cloud surrounds our solar system with billions of icy bodies at distances as far out as 50,000 times the distance between the sun and Earth.

Now these planets are likely to be colder than Hoth, but who knows what we could do with some extreme terraforming…
