Evolutionary Biology News

Evolutionary biology is the scientific study of the processes that have given rise to the diversity of life on Earth over billions of years. This discipline focuses on the history of life forms, their genetic changes over generations, and the environmental interactions that drive these changes. Central to evolutionary biology is the theory of evolution by natural selection, formulated by Charles Darwin. This theory proposes that organisms that are better adapted to their environments are more likely to survive and reproduce, passing on favorable traits to succeeding generations. Evolutionary biology covers various subfields such as phylogenetics, which reconstructs the evolutionary relationships among species; population genetics, which studies the genetic composition of populations over time; and evolutionary developmental biology, which examines how developmental processes evolve. The field extends beyond biological sciences, influencing diverse disciplines like medicine, psychology, and ecology, providing insights into antibiotic resistance, the behavior of organisms, and the impact of climate change on species adaptation.
