In Talmud Bavli (Babylonian Talmud) we read:
“Adam was created alone, to teach you that anyone who destroys one soul from Israel [the Jewish people], scripture looks upon him as if he de- stroyed an entire world. And anyone who sustains one soul from Israel, scripture looks upon him as if he sustained an entire world. And [this, Adam’s singular creation, was for] peace among living beings, so a person will not say to his fellow: [My] father is greater than your father...Therefore, [since all humanity has one progenitor], each and every person is obligated to say: The world was created for my sake.”
שפנ םיַמה לָו אלמ םלוֹע דבא וּלּאכ בוּתכה וילע הלעמ ,לארשימ תחא שפנ דבאמה לכש ,ךָדמלל ,ידיחי םדא ארבנ לוֹדָ אבא וֹרבחל םדא רמאי אלּש ,תוֹירבה םוֹלש ינפמוּ אלמ םלוֹע םיַ וּלּאכ בוּתכה וילע הלעמ ,לארשימ תחא
םלוֹעה ארבנ יליבשב ,רמוֹל ביח דחאו דחא לכ ךְָיפל ךָיבאמ
In these few lines of Talmud (Sanhedrin 4:5) we encounter some of the most inspiring and most challenging ideas in our tradition. The common descent of all humanity from one mythic ancestor is a story that should inspire unity, as all human beings are related to one another, either as members of our extended families or as very distant cousins. This is a beautiful thought, not inconsistent with the contemporary genetic evidence that we are all descended from Mitochondrial Eve.
