In a recent discussion on The Discovery Institute’s ID the Future podcast, geologist Casey Luskin explained that the original “98-99%” figure was derived from a single protein-to-protein comparison before the chimp genome was sequenced. Since then, we’ve gained a great deal more precision. According to Luskin, humans and chimps have about 35 million single base-pair genetic differences and five million insertion-deletion differences. Humans also have 689 unique genes not found in chimps. And while there are different ways of quantifying the differences, almost none of these ways yield the famous “98-99%” number. For example, in 2018, Queen Mary University of...
