L_4_04 — Ancient Proteomics and Paleoproteomics
Paleoproteomics — the recovery and analysis of ancient proteins from archaeological and paleontological specimens — has emerged as a revolutionary complement to ancient DNA (aDNA), dramatically extending the temporal and
L_4_06 — Epigenetics and Transgenerational Inheritance
Epigenetics — the study of heritable changes in gene expression that occur without alterations to the DNA sequence itself — has transformed modern biology by revealing a layer of regulatory information "above" the genome
L_4_17 — Transgenerational Epigenetic Trauma
Transgenerational epigenetic inheritance of trauma — the hypothesis that severe stress, famine, or psychological trauma experienced by one generation can alter the epigenetic marks (DNA methylation, histone modifications
L_4_01 — Ancient DNA from Sediment — Environmental DNA Revolution
Environmental DNA (eDNA) recovery from sediments has revolutionized our ability to detect the presence of organisms — including ancient humans — without requiring the discovery of any bones, teeth, or artifacts. The land
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_08 — East Asian Genetics and Population History
East Asia — comprising China, Japan, Korea, Mongolia, Taiwan, and mainland Southeast Asia — is home to the largest human population concentration on Earth and harbors a complex genetic history shaped by major north-south
L_2_07 — European Genetics and Three Ancestral Populations
The genetic history of Europe has been revolutionized by ancient DNA, revealing that most present-day Europeans can be modeled at a broad level as mixtures of three major ancestral components assembled over the past ~10,
L_2_01 — Domestication Genetics — How Humans Reshaped Life
Domestication — the genetic transformation of wild species into human-dependent organisms — ranks among the most consequential biological processes in Earth's history.
L_2_10 — Human–Dog Co-Evolution: 40,000 Years Together
The domestication of the dog (Canis lupus familiaris) from gray wolves (Canis lupus) represents the oldest known domestication event and one of the most consequential interspecies relationships in human history — predati
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_14 — Sex-Biased Admixture: Patrilocal vs. Matrilocal Migration
One of the most powerful revelations from ancient and modern DNA studies is that human migration, conquest, and admixture are almost never sex-neutral — they are systematically biased toward one sex or the other, produci
L_2_15 — Population Structure of the Ancient Near East: Farming Spread Genetics
The Neolithic Revolution — the independent invention of agriculture in the Fertile Crescent (~10,000-8,000 BCE) — was one of the most consequential transformations in human history, and ancient DNA has revealed that the
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_2_04 — Oceanian Genetics and Pacific Migration
The human settlement of Oceania represents the last major expansion of Homo sapiens across the globe, and the most remarkable feat of maritime exploration in human history. It occurred in two major phases separated by ~4
L_3_06 — Genetics of Intelligence and Cognition
The genetics of intelligence — one of the most studied yet contentious areas in behavioral genetics — has established that cognitive ability, as measured by standardized tests, has a substantial heritable component (~50–
L_3_09 — HLA Diversity and Immune System Evolution
The Human Leukocyte Antigen (HLA) system — the human version of the Major Histocompatibility Complex (MHC) found in all jawed vertebrates — is the most polymorphic gene region in the entire human genome. Located on chrom
L_3_14 — Genetic Bottleneck Recovery and Founder Effects
A genetic bottleneck occurs when a population's size is drastically reduced, causing a random loss of genetic variation (alleles) that cannot be recovered through subsequent population growth. Founder effects are a speci
L_3_13 — Human Accelerated Regions: What Makes Us Genetically Unique
Human Accelerated Regions (HARs) are short segments of the genome that were highly conserved across millions of years of mammalian evolution — indicating strong functional constraint — but then underwent a burst of rapid
L_3_05 — Blood Type Genetics and the ABO System
Blood group genetics represents one of the earliest and most clinically important applications of Mendelian inheritance in human biology. Karl Landsteiner's discovery of the ABO blood group system (1900–1901) — which ear
L_3_18 — Horizontal Gene Transfer in Eukaryotes
Horizontal gene transfer (HGT) — the movement of genetic material between organisms through mechanisms other than vertical parent-to-offspring inheritance — was long considered a predominantly prokaryotic phenomenon, cen
