Human Georgian Skull Fuels Dilemma

Georgian Skull International teams of paleoanthropologists for more than two decades have been discovering human-like fossils from a medieval archaeological site in the former Soviet Republic of Georgia known as Dmanisi. A new human Georgian skull fuels the dilemma further. The first four human-like fossils were discovered in 1991 by David Lordkipanidze of the Georgian National Museum in Tbilisi.

Increased archaeological interest in this Georgian site began in 1936 following the discovery of ancient and medieval artifacts. The discovery of teeth from an extinct rhino in 1983, followed by the discovery of stone tools in 1984, led to an increased archaeological and paleontological interest in Dmanisi. Last week the discovery of a fifth Dmanisi skull reported in the journal Science fuels the escalating dilemma of the struggling human evolution industry.

Oxygen-Free Atmosphere

OxygenThe scourge of evolution has re-emerged−this time with renewed vengeance.  Scientists have long known that extremely low levels of free-oxygen [< 10-5] atmosphere on early Earth are critical for any viable origin of life model of evolution.

The atmospheric concentration of oxygen in the origin of life controversy stems from the laws of organic chemistry. The autonomous assembly of complex organic molecules has only been observed in an oxygen-free atmosphere.  

Geophysicists Stephen C. Meyer of the University of Cambridge notes in Signature in the Cell that “even a small amount of atmospheric oxygen will quench the production of biologically significant building blocks and cause biomolecules otherwise present to degrade rapidly.” Oxygen-free has not always been an evolution scourge, however.
