The evolution of pathogens has received attention in a wide range of scientific fields, such as epidemiology, demography, and evolutionary ecology. Understanding pathogen evolution is particularly ...

A scaling law relates the expected number of mutants to the total population size of cells in a spatially constrained but growing population, which could help clinicians predict when cancers or ...

Antibiotic resistance and tolerance are thought to be the key phenotypic traits that underpin evolutionary adaptation to antibiotics. However, the concepts of resistance and tolerance can be traced ...

Most of the 65 chimpanzees subjected to whole-genome sequencing were captive or rescued and cared for in zoos or sanctuaries 14,15. Ultimately, researchers are aiming to understand the genome-scale ...

Evolution is always happening — so why can't we see it? A biologist explains the timescale problem, election pressure, and ...

For over a thousand years, the story of human evolution was simple: Homo sapiens developed in Africa between 200,000 and 300,000 years ago from a single line of forebears. But today, one research has ...

In his 1989 book Wonderful Life, the late Harvard scientist Stephen Jay Gould imagined rewinding life’s history to an early ...

The study published in PNAS sets out how, in just 1,500 years, the Copts have acquired a genetic variant that protects them from contracting malaria after mixing with other Sudanese populations. The ...

A study combining the growing number of ancient genomes with those of living people has given us our best picture yet of how humans have evolved over the past 10,000 years or so. It shows that people ...

In 1859, Darwin imagined evolution as a slow, gradual progress, with species accumulating small changes over time. But even he was surprised to find the fossil record offered no missing links: the ...

Spanish biologist Ignacio Paulin became fascinated by the behavior of these fish, in a project that could now disappear due ...
