You got your panspermia in my abiogenisis!
In an article over on sciam, researchers have found that meteor-like impacts can also catalyze the formation of life’s chemical precursors.This could be in contradiction or in complement to asteroids and comets being the delivery vehicle for such molecules.
I’m finding it amusing now that there seem to now be so many ways that the chemical constituents for life may have formed on the early earth. That the miracle would now be that they did not form.
“Hay, paw! why is there no life on this planet? ?”
“That son! well, that’s the miracle of jesus!”
The sciam entry notes that the paper covering this research appears in Nature Geoscience.
