TED-Ed: Where do genes come from? - Carl Zimmer

The video explores the origin and evolution of genes, starting from primitive microbes to the diverse genes present today. It explains how gene duplication and mutations lead to new functions and how non-coding DNA can give rise to new genes. Examples include the evolution of genes for odor detection in humans and venom production in snakes. The process of gene diversification is ongoing, contributing to the adaptability and survival of species.

Can you explain how a gene can change its function over time?

What is the significance of random DNA sequences in gene formation?
