Junking the Myth of Human/Chimp Similarity — Casey Luskin

Casey Luskin shows how the common claim that humans are about 99% genetically similar to chimpanzees is misleading. Citing newer research, Luskin suggests the difference may be closer to about 15% when the entire genome is considered. Earlier comparisons overstated similarity due to methodological choices, such as aligning genomes in ways that minimized differences. Moreover, much of the genetic difference — especially in repetitive DNA — is functionally important, not “junk.” It influences things like brain development and gene regulation. Luskin notes that in any case percentage similarity alone cannot prove common ancestry, since similarities could also be explained by “common design.” The human genome, it turns out, supports a view of human uniqueness rather than shared evolutionary origins.
