A new review highlights how human evolution has shaped the presence of pathogenic variations in DNA damage repair (DDR) genes, offering a new perspective on why modern populations face increased ...

Conventional wisdom holds that sexual reproduction evolved because it enables organisms to shuffle, or recombine, different alleles (versions of a gene) in the next generation, producing the genetic ...

Adaptive evolution arises when heritable genetic variation confers a fitness advantage under changing environmental or ecological conditions. Central mechanisms include the generation of variation ...

The genetic culprits responsible for the spread of multidrug resistance (MDR) in bacteria have been identified by new research mapping 100 years of bacterial evolution. Experts at the Wellcome Sanger ...

A 30-year-long study of a small population of marine snail shows how evolution can adapt to environmental changes quite rapidly. This study revealed how a specific ecotype of the snail changed its ...

Genome assemblies from 65 individuals, representing a variety of the world’s populations, are advancing the scientific exploration of complex genetic structural variation. Structural variations are ...

Humans are still evolving, and Tatum Simonson, PhD, founder and co-director of the Center for Physiological Genomics of Low Oxygen at University of California School of Medicine, plans to use ...

A genomic study of human and selected nonhuman primate centromeres has revealed their unimaginable diversity and speed of evolutionary change. Although centromeres are vital to proper cell replication ...

Some variation is the result of differences in the surroundings, or what an individual does. This is called environmental variation. Humans, dogs and goldfish are examples of species. Different ...
