The Rise of Mammals and Early Humanity
Days 113–140 trace the rise of mammals after the great extinction, the emergence of primates, and the long evolutionary journey toward modern humans: bipedalism, tool use, and the first cultures. Pentecost/Shavuot falls across five possible days spanning Aries and Taurus — Aries 21, Aries 28, Taurus 7 (canonical), Taurus 14, and Taurus 21.
Aries has 28 days and covers days 113–140 of the Gaian year · Gaiad chapters 113–140.
