L_1_01 — Ancient DNA & Population Genetics
Modern paleogenomics has shown that human evolution was shaped by interbreeding, population structure, and repeated demographic turnover rather than a simple single-line progression. Ancient DNA revealed previously unkno
L_1_06 — Human Migration Synthesis — DNA, Language, and Culture
The synthesis of genetic, linguistic, and archaeological evidence has transformed understanding of human migration over the past three decades.
L_1_17 — Homo Floresiensis
Homo floresiensis is one of the most controversial hominin discoveries of the 21st century. Found in Liang Bua cave on the Indonesian island of Flores by Mike Morwood and Thomas Sutikna in September 2003 (announced Octob
L_1_04 — Archaic Human Species Synthesis
The human evolutionary tree is far more complex than the older linear model suggested. Fossils, ancient DNA, and proteomics now show that Homo sapiens overlapped with several other hominin lineages, including Neanderthal
L_1_07 — Genetic Bottlenecks, Founder Effects, and Toba
Genetic bottlenecks — dramatic reductions in population size that slash genetic diversity — and founder effects — the reduced variation carried by small colonizing groups — have profoundly shaped the genomes of species f
L_1_16 — Denisovan Genetics and Legacy
The Denisovans — an extinct group of archaic humans first identified in 2010 from ancient DNA extracted from a finger bone fragment found in Denisova Cave, Altai Mountains, Siberia (~41,000 years old) — represent one of
L_4_13 — Ancient DNA: Methods, Revelations, and Ethical Debates
Ancient DNA (aDNA) — genetic material recovered from biological remains thousands to hundreds of thousands of years old — has revolutionized our understanding of human evolution, migration, and population history. The fi
L_4_05 — Paleogenomics Methods and Ancient DNA
Paleogenomics — the study of ancient genomes — has transformed archaeology, anthropology, and evolutionary biology over the past two decades, recognized by the 2022 Nobel Prize in Physiology or Medicine awarded to Svante
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_16 — Ancient Pathogen Genomics: Disease DNA from the Archaeological Record
Ancient pathogen genomics — the recovery and analysis of microbial DNA from archaeological remains — has revolutionized understanding of historical pandemics and pathogen evolution. The field was transformed when Johanne
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_4_12 — CRISPR Gene Drives and Population Genetics Ethics
CRISPR gene drives — genetic engineering systems that combine CRISPR-Cas9 gene editing with super-Mendelian inheritance to spread a modified gene through an entire wild population far faster than natural selection — repr
L_4_10 — Sex Chromosome Evolution
Sex chromosomes — the genetic elements that determine biological sex in many organisms — represent one of the most remarkable stories in genome evolution. In mammals, the XX/XY system prevails: females have two X chromos
L_4_14 — Ancient Pathogen Genomics
Ancient pathogen genomics — the recovery, sequencing, and analysis of pathogen DNA from archaeological remains — has revolutionized our understanding of past pandemics, pathogen evolution, and human-disease coevolution.
L_2_12 — Paleogenomics of Africa: The Cradle Revisited
Africa is the cradle of human evolution — the continent where Homo sapiens originated, where the deepest branches of the human family tree diverge, and where the greatest genetic diversity in our species is found. Yet pa
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_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
