Simple biology. Solid science.
Learn how evolution works without the jargon.
This site explains evolution in plain language, corrects common myths, and shows why evolution matters in medicine, farming, and everyday life.
How evolution builds diversity
Small inherited differences appear, environments filter them, and lineages branch over time.
Keep explanations scientifically correct.
Use simple words first and define harder terms when needed.
Show evidence, not just claims.
Why evolution matters
Evolution helps explain antibiotic resistance, new virus variants, crop breeding, and why living things share common features.
What is evolution?
Evolution is the change in inherited traits in a population over generations. It explains how populations shift, split, and remain related through common ancestry.
Natural selection
Natural selection happens when individuals with certain inherited traits leave more offspring than others in a particular environment.
Is evolution just a theory?
In science, a theory is a well-tested explanation supported by evidence. Evolution is called a theory in that strong scientific sense.
Antibiotic resistance
Antibiotic resistance evolves when bacteria with resistance traits survive treatment and reproduce more successfully than others.
