. . . unfortunately there are no data for the Very Beginning. . . . Only God knows what happened at the Very Beginning (and so far She hasn't let on).
-Leon Lederman

Welcome!

Welcome to a discussion about Judaism and science, about fact and fiction, fantasy and faith. Now in its fourth year, this site has already explored a wide range of issues, from archeology to zygotes and from adam (mankind) to t’filah (prayer). And we have done so unsponsored and unencumbered by any particular denomination.

Along the way, we have encountered some interesting ideas, met some fascinating people and even gained some new perspectives. And our journey has really just begun. All who are interested in a thoughtful, respectful and constructive dialogue are invited to participate.

 

The Genome and Souls of Ashkenazi Jews

   The Ashkenazi Jewish population is a genetic isolate gene pool almost equally close to European and Middle Eastern groups according to a highly detailed genetic study published in Nature Communications on September 9, 2014. The report is a high-depth analysis of the sequencing of 128 complete genomes of Ashkenazi Jews controls compared with European complete genome samples from 26 Flemish people from Belgium.

Reconstruction of recent Ashkenazi Jewish history from such genetic segments confirms a recent bottleneck of merely 300-400 individuals living in Central Europe, 25-32 generations ago, in the 13th-15th centuries (1200-1400). This bottleneck was the result of wide spread massacres of Jews in the Rhine Valley during the first three crusades; and additional massacres of Jews who were blamed by European Christians for causing the Bubonic Plague (1328-1351) which killed a third of the population in Europe (and almost half in urban areas). read more

Why Did Homo Sapiens Become Gentler?

Although, based on the news media, it is difficult to believe that Homo Sapiens (“HS”) have become biologically gentler, an apparent reduction in testosterone about 50-60,000 years ago led to human personalities becoming gentler and human faces becoming more feminine, according to a new study based on measurements of more than 1,400 ancient and modern skulls. This led people to have gentler personalities and to great advances in art and tool making.

The study, published in the August 2014 issue of the journal Current Anthropology, found that human skulls changed in ways that indicate a lowering of testosterone levels at around the same time that culture was blossoming. The study’s lead author, Robert Cieri, said: The modern human behaviors of technological innovation, making art and rapid cultural exchange probably came at the same time that we developed a more cooperative temperament resulting from having a little less testosterone in action.  read more
