Further to Oldest human fossil found, 400k years “earlier than previously thought,” neuroscientist David A. DeWitt writes to say,
That is a real problem since it means that humans overlapped with australopithcines including especially sediba which is a mere 2 million years old.
Humans dated 2.8 million years ago? Sophisticated tools used by H. erectus? Neanderthal genes in modern humans? Range of variation in Dmanisi overlapping H. erectus to modern humans? A. sediba is a mixture of Homo and Australopithecine remains in South Africa?
What we essentially have is a Cambrian explosion type phenomenon for human origins.
The ridiculous level of uncertainty in the field of human evolution DeWitt: “Look at how messed up this field is. Genetic evidence supports Neanderthals and modern humans interbred. The Dmanisi skulls show such variation as to incorporate all of the various Homo specimens.”
History of man unravels in “huge fraud”
Contemplating Bill Nye’s skulls slide “I can only conclude that the sole purpose of showing such a slide was to confuse and obfuscate, not educate.”
But wait! It’s not messed up as long as hundreds of pop science writers refrain from wondering.
