How Humans Are Almost Identical to Chimps, According to DNA

The video explores the genetic differences between humans and chimpanzees, highlighting that while our DNA is only about 1% different, the actual functional differences are more complex. It discusses the types of genetic variations, such as single nucleotide changes, insertions, deletions, and gene duplications, and their impact on traits. The role of gene regulation in evolution and the development of human-specific traits is emphasized. The video also covers current research methods, including DNA methylation patterns and computational tools, to understand these differences and their implications for human evolution.
