Q_3_08 — Planetary Formation and Protoplanetary Disks
Planets form within protoplanetary disks — rotationally supported structures of gas and dust orbiting newly formed stars, with typical masses of 0.1–10% of the stellar mass, radii of 10–1000 AU, and lifetimes of ~1–10 mi
INTERDOC_13 — Out of Africa vs. Multiregional: The Synthesis That Changed Everything
The two dominant models of human origins battled from the 1980s through the 2010s. Chris Stringer and Peter Andrews championed the Recent African Origin (RAO) model (1988, Science): anatomically modern humans evolved exc
ZB_5_09 — Phenology: Seasonal Timing in Nature
Phenology — the study of the timing of recurring biological events (leaf-out, flowering, fruiting, autumn senescence, insect emergence, bird migration, amphibian breeding) in relation to seasonal and climatic drivers — h
ZB_5_01 — Biological Rhythms Beyond Circadian
While circadian (~24-hour) rhythms are the best-studied biological oscillations (2017 Nobel Prize to Hall, Rosbash, Young), life is permeated by rhythms operating across all timescales — from millisecond neural oscillati
ZB_3_24 — Phenological Mismatch: When Ecological Timing Goes Wrong
Phenological mismatch — the decoupling of historically synchronized ecological events due to differential responses to environmental change — has emerged as one of the most consequential ecological impacts of anthropogen
ZC_4_22 — Urban Anthropology & City as Culture
Urban anthropology — the ethnographic study of life in cities — has grown from a marginal subfield to one of the most vital areas in contemporary social science as humanity has become a predominantly urban species: since
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
O_3_20 — Microplastics, Nanoplastics, and the Ubiquitous Contamination Crisis
Microplastics — plastic particles smaller than 5 mm in diameter, with nanoplastics defined as smaller than 1 μm — have become the most pervasive anthropogenic contaminant on Earth. Since mass production of synthetic poly
O_5_14 — Ocean Acoustic Anomalies: Bloop, Julia, Upsweep, and SOSUS
Since the end of the Cold War, the repurposing of the US Navy's SOSUS (Sound Surveillance System) — a network of fixed underwater hydrophone arrays originally deployed across the Atlantic and Pacific ocean floors during
D_3_07 — Nan Madol — Megalithic City on the Reef
Nan Madol is a ruined megalithic city located off the southeast coast of Pohnpei (formerly Ponape), Federated States of Micronesia, in the western Pacific Ocean. Built on a series of ~92 artificial islets constructed on
ZD_5_02 — Digital Preservation and the Longevity of Knowledge
Digital preservation — the set of policies, strategies, and actions required to ensure continued access to digital information over time — addresses one of the great paradoxes of the information age: humanity is producin
L_1_03 — Mitochondrial Eve, Y-Chromosomal Adam & Population Origins
Mitochondrial Eve and Y-chromosomal Adam are the most recent common ancestors of all living humans along strictly maternal and strictly paternal lines. They were not the first woman and man, were not a couple, and do not
L_2_02 — Population Genetics and Hardy-Weinberg Equilibrium
Population genetics — the mathematical study of allele frequency change in populations — provides the quantitative framework underlying evolutionary biology. The Hardy-Weinberg principle (1908), independently derived by
L_2_03 — Ancient African Genetics
Africa harbors the greatest human genetic diversity on Earth — a direct consequence of being the continent of human origin, where populations have accumulated genetic variation for ~300,000+ years. Modern African populat
L_2_06 — South Asian Genetics and Population History
South Asia harbors one of the most genetically diverse and internally structured population histories of any world region, reflecting deep settlement, repeated admixture, and long periods of extreme endogamy. The best-su
L_2_05 — Americas Peopling Genetics
The peopling of the Americas is one of the clearest cases where ancient DNA and archaeology have converged to overturn an older narrative. The core model now favored by genetics is that the main ancestry of Indigenous Am
L_5_16 — Archaeogenetics: Ancient DNA and the Human Past
Archaeogenetics — the extraction and analysis of DNA from ancient human, animal, and plant remains — has transformed our understanding of human history since the field's breakthrough in 2010. Advances in next-generation
L_5_09 — Human Microbiome Co-Evolution: Ancient Gut Companions
The human microbiome — the trillions of bacteria, archaea, fungi, and viruses that inhabit our bodies, particularly the gastrointestinal tract — is not merely a passive inhabitant but a co-evolved partner that has shaped
P_5_02 — Computational Phylogenetics of Mythology
This document examines Computational Phylogenetics of Mythology, a topic within the Philosophy Meaning research area. Key areas of investigation include The Traditional Approach: Comparative Mythology, The Biological Ana
P_2_09 — Cosmopolitanism and Global Ethics
Cosmopolitanism — from the Greek kosmopolitēs ("citizen of the world") — is the philosophical tradition asserting that all human beings belong to a single moral community regardless of nationality, ethnicity, or culture.
