Underground cave dating from the year 1 A.D. exposed in Jordan Valley

Mon, 22 Jun 2009 00:00:00 EDT

High population density triggers cultural explosions

Thu, 04 Jun 2009 00:00:00 EDT

(University College London) Increasing population density, rather than boosts in human brain power, appears to have catalyzed the emergence of modern human behavior, according to a new study by University College London scientists published in the journal Science. High population density leads to greater exchange of ideas and skills and prevents the loss of new innovations. It is this skill maintenance, combined with a greater probability of useful innovations, that led to modern human behavior appearing at different times in different parts of the world.

They are also documenting the timelines over which those giant marine life populations declined.

The role of astronomy in antiquity examined in new book

Mon, 18 May 2009 00:00:00 EDT

(Springer) In his new authoritative study of archaeoastronomy, "Mysteries and Discoveries of Archaeoastronomy," author Guilio Magli asks, "Was it an attempt to reproduce the sky on Earth? To bring down the power of stars to where they could see it, worship it, and use it?" Magli examines the role of astronomy in antiquity and provides a clear, up-to-date survey of current thinking on the motives of the ancients for building fabulous monuments all over our planet.
