Understanding Mutations and Evolution

The video explores the concept of mutations, their historical fascination, and their crucial role in evolution. It discusses how mutations occur in both humans and animals, contributing to genetic diversity and disease resistance. The video also highlights human influence on evolution through selective breeding and the advancements in genetic research, including potential applications in medicine and genetic engineering.

What is a mutation in the context of genetics?

• A change in the diet

• A change in the DNA sequence

• A change in the environment

• A change in the weather
