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_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_09 — Genetic History of the Americas: Clovis to Contact

The genetic history of the Americas — from the initial peopling of the New World to the devastating population collapse after European contact — is one of the most intensively studied and rapidly evolving areas of paleog

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_11 — Genetics of Taste and Dietary Adaptation

Taste perception — the ability to detect sweet, salty, sour, bitter, and umami (savory) stimuli — is mediated by genetically encoded receptor proteins whose variation across individuals and populations reflects evolution

L_3_12 — Genetics of Pigmentation: Skin, Hair, and Eye Color Evolution

Human pigmentation — the variation in skin, hair, and eye color across populations — is one of the most visible and best-understood examples of natural selection in our species. Pigmentation is determined primarily by th

Human pigmentation — skin, hair, and eye color — is one of the best-understood complex traits in human genetics, with a relatively modest number of genes explaining a large proportion of variation compared to most polyge

L_5_07 — Genetics of Speech and Language: Beyond FOXP2

Language is humanity's most distinctive cognitive ability — and identifying its genetic basis has been a central goal of human genetics and neuroscience since the discovery of the KE family and the FOXP2 gene. The KE fam
