The authors then searched for locations where the ancient sequences differed from the ones found in modern humans. To be confident that the difference was real, the researchers required that it show up in multiple overlapping fragments and in samples analyzed at two different locations. A clear difference They came up with two differences that show up in the Homo erectus proteins, but not in modern humans. Oddly, they’re both in the same protein, called ameloblastin. …
