Genetic analysis indicates that the human and chimpanzee genomes are approximately 99 percent identical at the sequence level. However, this figure is nuanced; when accounting for insertions and deletions in the organization of those sequences, the homology is estimated to be about 96 percent.12

Research suggests that the lineages of humans and chimpanzees diverged between 6.5 million and 9.3 million years ago. This high degree of genetic similarity underscores the shared evolutionary history between the two species.32
