"Advanced paleoliths are more finely worked than the crude paleoliths. But industries containing advanced paleoliths may also contain cruder tools. We shall first discuss the discoveries of Florentino Ameghino, as well as the attacks upon them by Ales Hrdlicka and W. H. Holmes. Next we shall consider the finds of Carlos Ameghino, which provide some of the most solid and convincing evidence for a fully human presence in the Pliocene. We shall then proceed to anomalous finds made at sites in North America, including H..."

"After decades of intensive effort by both experimental and theoretical physicists worldwide, a tiny particle with no charge, a very low mass and a lifetime much shorter than a nanosecond, dubbed the "axion," has now been detected by the University at Buffalo physicist who first suggested its existence in a little-read paper as early as 1974...."

"A pre-human fossil found in a South African cave may be more than a million years younger than was previously thought, a new study has discovered. If the new findings are right, the fossil is not a direct human ancestor, as had been believed, but instead belongs to a side branch of the evolutionary tree that eventually led to modern apes and humans...."

" There is undeniable proof that water once existed on the planet Mars, a team of researchers has concluded in a series of 11 articles this week in a special issue of the journal Science...."

"As most everyone knows, a meteor struck Earth with violent force 65 million years ago and wiped out the dinosaurs. The crater was discovered in Mexico's Yucatan peninsula barely 15 years ago, yet already schoolchildren can recite the easy-to-grasp explanation for the end of an epoch.

Problem: Gerta Keller thinks it is flat-out wrong...."

" A fossil-hunting trip to celebrate a son's homecoming resulted in the recent discovery of an ancient sea monster in central Montana. Believed to be approximately 70 million years old, its skull and lower jaw represent the first complete skull of a long-necked plesiosaur found in Montana, according to Montana State University experts. The skull is said to be one of the best specimens of its kind in North America...."

"Planetary scientists have found evidence of a meteor impact much larger and earlier than the one that killed the dinosaurs -- an impact that they believe caused the biggest mass extinction in Earth's history...."
