Evolutionary Biology Articles Index
Evolutionary biology is a pivotal subfield of biology that examines the four primary mechanisms of evolution: natural selection, mutation, genetic drift, and gene flow. This field seeks to explain the vast biological diversity observed in nature and how organisms adapt and evolve over time.
Key Topics in Evolutionary Biology
Abiogenesis
Abiogenesis refers to the origin of life from non-living matter, a foundational concept in understanding how life began on Earth. It is intricately linked to evolutionary biology as it sets the stage for the subsequent evolution of living organisms.
Adaptation
Adaptation is a core concept where organisms develop traits that enhance their survival and reproduction in specific environments. These adaptations result from the pressures of natural selection acting on populations over generations.
Adaptive Mutation
Adaptive mutation refers to genetic changes that provide a selective advantage to organisms. Unlike random mutations, these are thought to occur in response to environmental stimuli.
Evolutionary Developmental Biology (Evo-Devo)
Evolutionary developmental biology, commonly known as evo-devo, explores how the development processes of organisms influence evolutionary changes. It compares the developmental processes across different species to understand evolutionary transformations.
Mito-Nuclear Discordance
Mito-nuclear discordance involves evolutionary incongruence between mitochondrial and nuclear genomes. This phenomenon can obscure signals of introgression and is a widespread but underappreciated aspect of genetic evolution.
Interdisciplinary Fields
Ecology and Evolutionary Biology
This interdisciplinary field examines the interactions between organisms and their environments, highlighting how these interactions drive evolutionary changes. It combines principles of ecology and evolutionary biology to understand how environmental pressures influence evolutionary processes.
Ecological Evolutionary Developmental Biology (Eco-Evo-Devo)
Eco-evo-devo is an integration of ecology, developmental biology, and evolutionary biology. It examines how ecological and evolutionary processes shape the development of organisms and vice versa.
Contingency in Evolutionary Biology
Contingency in evolutionary biology describes how the historical context of a lineage can affect evolutionary outcomes. It emphasizes the role of chance and historical events in shaping the evolutionary paths of species.
Academic and Professional Bodies
European Society for Evolutionary Biology
The European Society for Evolutionary Biology (ESEB) is a professional organization founded in Basel, Switzerland, in 1987. It brings together evolutionary biologists to share research and promote advancements in the field.
Journal of Evolutionary Biology
The Journal of Evolutionary Biology is a peer-reviewed publication that covers a wide range of topics in evolutionary biology, from theoretical studies to empirical research.
