Summary

Story summary

Humans and chimpanzees share approximately 98.8% of their DNA, but this figure can be misleading.
Significant differences arise in noncoding DNA, which makes up about 98% of the genome.
Around 15% to 20% of human DNA has no clear counterpart in chimp DNA.
Recent studies indicate the genetic difference may exceed 10%.
Variability within chimpanzee species can reach up to 9%.
Minor DNA changes can greatly influence gene expression and traits.
Despite genetic similarities, gene expression results in notable species differences.
