What’s in the 4% of our DNA that makes us different from chimps?

The video explores the genetic differences between humans and chimpanzees, highlighting that while the human genome is only about 1% different from that of chimpanzees, the differences are more complex when considering insertions, deletions, and gene regulation. It discusses how these genetic variations contribute to unique human traits, such as language and brain development, and the challenges in understanding these differences. The video also covers current research methods, including DNA methylation and computational tools, and emphasizes the need for further innovation to fully comprehend the human condition.
