Researchers have found that certain bacteria carry a naturally occurring system, built from repurposed CRISPR components, ...

Antibiotic resistance, when infection-causing bacteria evolve so they are no longer affected by typical antibiotics, is a global concern. New research at the University of Tokyo has mapped the ...

When most people think about natural selection, they imagine individuals competing with one another: The fastest animal escapes predators, the strongest plant produces more seeds, and the most ...

The virus that causes COVID-19 has accomplished something that school boards and other policy makers often refuse to do. It has given us a vivid, real-time lesson in how biological evolution works, ...

This post is the second in a series on evolutionary medicine, the application of the principles of evolution to the understanding of health and disease. Read the previous entry here. It's a basic ...

Humans' exposure to high temperature burn injuries may have played an important role in our evolutionary development, shaping how our bodies heal, fight infection, and sometimes fail under extreme ...

The common view of natural selection is based solely on the individual: A trait allows an organism to out-compete its rivals and is thus passed down to its offspring. To suggest otherwise can provoke ...

Gene editing has advanced in many ways over the past few decades. Most methods in genetic engineering involve altering the genomes of animal models like mice and zebrafish, or mammalian cells growing ...
