In the sediments left by the eruption of a Mexican volcano, researchers discovered ancient human traces. A few months ago, the researchers pointed out that footprints were 40,000 years ago. According to this, the species Homo sapiens arrived in America earlier than expected. Now, however, the age of volcanic rocks has been recalculated and the result is that the eruption occurred 1.3 million years ago. This totally distorts the theory, so now they do not believe that these traces are human traces.
