The evolutionary mystery of how new genes appear
In short: Life on Earth began with a basic toolkit of genes, but modern organisms possess thousands more. This video explores the mechanisms of mutation and multiplication that allowed life to expand its genetic repertoire over billions of years.
About 4 billion years ago, the first microbes on Earth survived using a foundational set of genes. However, the vast diversity of life today—from humans to large organisms—requires a much larger genetic library. Carl Zimmer examines how these additional genes emerged through the processes of mutation and multiplication.
The video explains the transition from these early, simple genetic systems to the complex genomes we see today. It matters because understanding how genes are created is fundamental to understanding the history of biological complexity.
