The Agricultural Revolution, or Neolithic Revolution, was a pivotal moment in human history that led to significant evolutionary changes. As societies transitioned from hunter-gatherers to agricultural lifestyles, they faced new selection pressures. These included dietary shifts and increased exposure to zoonotic diseases, prompting genetic adaptations like lactase persistence and disease resistances. The Holocene epoch saw an acceleration in human evolution, with regional adaptations to diet and disease, and changes in brain size. The ongoing evolution of humans continues to be influenced by environmental and societal factors, such as urbanization and living in extreme conditions.

The Agricultural Revolution led to evolutionary adaptations such as the development of enzyme variants and lactase persistence in various populations
The Holocene epoch, beginning around 11,700 years ago, saw a rapid acceleration of human evolution, particularly among agricultural societies in Eurasia
Human migration and settlement patterns have led to the development of various disease resistances and dietary adaptations
Nutrient Deficiencies
The shift to agricultural diets, which were often less diverse and nutrient-rich, may have driven the evolution of traits such as lighter skin in Europeans
Evolution of Lactase Persistence
The evolution of lactase persistence allowed for the digestion of milk beyond infancy and supported the spread of pastoralism
Anthropological research has uncovered distinct evolutionary developments among human populations in Africa, Asia, and Europe, shaped by regional environments and lifestyles
The human brain has experienced changes, potentially decreasing in size over the past 5,000 years due to the reduced survival demands of agricultural societies compared to hunter-gatherers
The interaction between cultural practices and genetic evolution has been a significant force in human development, exemplified by the emergence of dairy farming and the associated genetic adaptation of lactase persistence
Adaptations to Environmental and Societal Pressures
Human evolution continues in response to environmental and societal pressures, such as the development of genetic resistance to diseases like malaria and adaptations to urbanization and extreme environments
