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 ...

Beneficial mutations happen quite frequently, but the world changes too fast for them to stick.

A new Yale-led study provides one of the most detailed and comprehensive analyses to date of genetic variation in human ...

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 ...

The concept of punctuated equilibrium was, to some, a radical new idea when it was first proposed by Stephen Jay Gould and Niles Eldredge in 1972. Now it is widely recognized as a useful model for one ...

In testing the genetic material of current populations in Africa and comparing against existing fossil evidence of early Homo sapiens populations there, researchers have uncovered a new model of human ...

Researchers have shed new light on how viral evolution, population immunity, and the co-circulation of other flu viruses shape seasonal flu epidemics. Researchers have shed new light on how viral ...

A groundbreaking DNA study has unveiled a hidden chapter in human evolution, revealing that all modern humans evolved from two ancient and distinct groups. This research, published in March 2025, ...

The University of California opened its doors in 1869 with just 10 faculty members and 40 students. Today, the UC system has more than 300,000 students and 265,000 faculty and staff, with 2.5 million ...

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 ...
