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 —

G_1_07 — Stable Isotope Analysis and Ancient Diets

Stable isotope analysis of human and animal remains — primarily the measurement of carbon ($\delta^{13}$C), nitrogen ($\delta^{15}$N), and sulfur ($\delta^{34}$S) isotope ratios in bone collagen, tooth enamel, hair kerat

G_1_09 — Provenance Analysis: Strontium, Lead, and Oxygen Isotope Sourcing

Isotopic provenance analysis has revolutionized archaeology by enabling researchers to determine where an artifact was made, where a person grew up, what they ate, and how far they traveled — all from the chemical signat

G_3_12 — Morphic Resonance and Formative Causation

Morphic resonance is a hypothesis proposed by Rupert Sheldrake (1981, A New Science of Life) that posits the existence of morphic fields — non-local, non-energetic fields that carry information about the habits (forms an

G_3_27 — Morphic Resonance vs Epigenetic Inheritance: A Rigorous Comparison

For decades, Rupert Sheldrake's morphic resonance hypothesis — that organisms inherit form and behavior through a non-material "morphic field" carrying patterns from past similar systems — has been the most prominent fri

O_1_11 — Earthquake Lights — Comprehensive Evidence and Mechanisms

Earthquake lights (EQLs) are anomalous luminous phenomena — flashes, glows, flames, orbs, and columns of light — reported in association with earthquakes throughout recorded history. Once dismissed as anecdotal or imagin
