G_4_17 — Microbiome Archaeology — Ancient Gut and Soil Microbes

Microbiome archaeology — the extraction and analysis of ancient microbial communities from archaeological materials (dental calculus, coprolites, mummified remains, soil sediments, ceramics) — has emerged since ~2012 as

G_1_05 — eDNA and Environmental DNA — Reading Invisible Life

Environmental DNA (eDNA) refers to genetic material shed by organisms into their environment — through skin cells, mucus, feces, urine, gametes, decomposing tissue, pollen, root exudates, and other biological residues —

O_5_01 — Permafrost, Cryosphere, and Frozen Time Capsules

Permafrost — permanently frozen ground covering approximately 25% of the Northern Hemisphere's land surface — is simultaneously a geological archive, a biological deep freeze, and a ticking carbon time bomb. Ice cores ex

D_5_02 — Labyrinth Tradition

The labyrinth appears across virtually every major civilization — from the Egyptian Labyrinth at Hawara (described by Herodotus as surpassing the pyramids) to Knossos, Chartres Cathedral, and Hopi Tápu'at designs. The cl

Human skin color is one of the most visible and most misunderstood traits in our species. The variation is primarily a product of natural selection balancing two competing needs: protection of folate (vitamin B9) from UV

L_1_13 — Homo Naledi: Underground Burial and Primitive Morphology

Homo naledi is one of the most unexpected and controversial hominin discoveries of the 21st century. Announced in 2015 by Lee Berger (University of the Witwatersrand) and an international team, the species was recovered

L_1_08 — Denisovans — Archaic Hominin Deep Dive

Denisovans are an extinct group of archaic hominins identified primarily through ancient DNA analysis rather than traditional fossil morphology — making them history's first hominins to be discovered by genetics. In 2010
