New DNA evidence suggests previous 'science' was flawed.
The DNA of Neanderthals and modern Man likely came from shared ancestry, not from interbreeding, says new research at University of Cambridge, published in PNAS journal this week.
Computer simulations were used by Cambridge evolutionary biologists Dr Anders Eriksson and Dr Andrea Manica to reassess evidence supporting interbreeding evolution.
This challenges previous 'science' - based on various lines of evidence - that modern humanity replaced Neanderthal Man with little or no gene flow between them.
Surprise, surprise. We hear this often. Much 'science' seems to be less about facts, and more about a scientist's assumptions.
The problem is, scientists often have no facts to prove their assumptions. Even Einstein made incorrect assumptions. He said nothing could emit from a black hole - Stephen Hawking proved it can.
Medical scientists often 'prove-assume' drugs are safe - later they're found to be dangerous or fatal.
Einstein, medical scientists, and origins of Man evolutionists put pieces of scientific-assumption jigsaws in positions they don't fit.
With the release of this week's DNA news, it seems more likely current 'scientific' assumptions on the origins of Humankind may eventually be disproved, and even be laughed at.
