Where did we come from, originally?
Regarding the very beginning, ie DNA, the recent analysis of an Australian meteorite provides evidence for Carl Sagan’s idea that we are of extra-terrestial origins:
Researchers discovered the organic molecules uracil and xanthine in the meteorite and confirmed they could not have formed on Earth. These molecules, called nucleobases, are precursors to DNA…
“Emergent life systems may have adopted nucleobases from meteoritic fragments for use in an early and primitive genetic material, enabling them to pass on their successful features to the next generations,” said study leader Zita Martins of Imperial College London.
Regarding our evolution from apes to humans, I came across an article at Nature.com that proposes a nuclear reactor could occur at the base of Earth’s mantle – providing heat and also radiation. The key factor for me is this:
Yet it is clear that natural nuclear reactors can occur. Crustal rocks at Oklo in Gabon, Africa, bear unambiguous evidence of spontaneous ignition of uranium fission in mineral deposits 1.7 billion years ago.
As humans, we originated in Africa. Radiation made it to the surface in Africa. Radiation causes mutations. Mutations can lead to evolution.
