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

Evolutionary Ecology: Adaptations and Evolutionary Responses in Ecological Contexts

by

Evolutionary ecology is a multidisciplinary field that integrates principles from evolutionary biology and ecology to study the adaptations, evolutionary responses, and interactions of organisms within ecological contexts. It seeks to understand how ecological factors such as resource availability, environmental conditions, predation pressures, competition, and symbiotic relationships shape the evolution of traits, behaviors, and genetic diversity … Read more

DNA reveals surprise origins of iconic mammoth

by

An international team led by researchers at the Centre for Palaeogenetics in Stockholm has sequenced DNA recovered from mammoth remains that are up to 1.2 million years old. The analyses show that the Columbian mammoth that inhabited North America during the last ice age was a hybrid between the woolly mammoth and a previously unknown … Read more

Researchers uncover the molecular dice game behind bee sex determination

by

A recent breakthrough in bee research conducted by a team from Heinrich Heine University Düsseldorf has shed light on the long-standing mystery of bee sex determination. Published in the journal Science Advances, their findings reveal a fascinating mechanism akin to a dice game. In the natural world, an organism’s biological sex carries significant implications for … Read more

Gorillas share genetic legacy with extinct lineage

by

Researchers from the University of Vienna in Austria and the Institute of Evolutionary Biology in Barcelona, Spain, recently published a groundbreaking study in the journal Nature Ecology and Evolution, shedding light on the evolutionary past of gorillas. Leading the study were Martin Kuhlwilm, a scientist from the Department of Evolutionary Anthropology at the University of … Read more

Ancient humans may have paused in Arabia for 30,000 years

by

According to the consensus among most scientists, the origin of modern humans can be traced back to Africa over 200,000 years ago. A significant migration event took place between approximately 60,000 and 50,000 years ago, during which humans dispersed across various parts of the world. However, recent research published in the Proceedings of the National … Read more
