Lizard genetics provide new perspective on evolution
Some colorful lizards and a mathematical formula from the finance sector have been used to build a new framework to model evolution.
Evolution, as a scientific topic, encompasses the study of heritable change in populations of organisms over successive generations, driven primarily by mechanisms such as mutation, natural selection, genetic drift, gene flow, and recombination. It investigates how genetic variation arises and is differentially propagated, leading to adaptation, speciation, and macroevolutionary patterns observable in phylogenies and the fossil record. Research in this area integrates population genetics, comparative genomics, quantitative genetics, and developmental biology to elucidate processes shaping genetic architecture, fitness landscapes, and phenotypic diversity, as well as the tempo and mode of evolutionary change across different ecological and genomic contexts.
