Evolutionary Genetics: Genetic Changes Over Generations

by

Evolutionary genetics is a field of study that explores genetic changes within populations and species over generations, elucidating the mechanisms and processes driving evolutionary processes. It integrates principles from genetics, molecular biology, population genetics, and evolutionary biology to understand how genetic variation, mutation, natural selection, genetic drift, gene flow, and other factors shape the genetic … Read more

Study links slow evolution in gars to their status as living fossils

by

In 1859, Charles Darwin introduced the term “living fossils” to describe organisms exhibiting minimal species diversity or physical deviations from their ancestors as seen in the fossil record. A groundbreaking study from Yale researchers, published in the journal Evolution, has shed light on the biological mechanisms underlying the existence of living fossils in nature. Focusing … Read more

Biology

by

Biology is the scientific study of life and living organisms. It explores a vast range of topics, including the structure, function, growth, origin, evolution, and distribution of living organisms. This discipline delves into various levels of biological organization, from molecules and cells to organisms and ecosystems. Through methods like observation, experimentation, and analysis, biologists seek … Read more

Sea snakes evolve to see an extended palette of colors

by

A recent publication in Genome Biology and Evolution, which was published by Oxford University Press, has made an intriguing discovery regarding the annulated sea snake. This venomous snake species, found in the waters surrounding Australia and Asia, seems to have evolved an extended range of color vision after its ancestors lost that ability due to … Read more
