Enzymes are the body's tiny workers, speeding up chemical reactions. Scientists have long used tools to compare enzymes based on their sequence, structure, and reactions. This helps them group enzymes into families and understand how they evolve. However, until recently, there was no way to compa
Mites are tiny creatures that play a big role in breaking down organic matter in soil. This helps in the carbon cycle, which is vital for life on Earth.

Game theory is a fascinating field that explores how different strategies play out in competitive situations. One key concept is the Evolutionarily Stable Strategy (ESS). This is a strategy that, if adopted by a population, cannot be invaded by any alternative strategy. It's like having a superpower
South Korea finds itself at a crossroads between science and religion. Evolution, a cornerstone of modern biology, faces stiff competition from creationism. This tension is not just about science. It is about how people view the world and their place in it. Evolution is widely accepted in the scien
