A new study helps establish a consistent, unambiguous conclusion that life’s origin on Earth occurred in a geological instant. This work casts additional doubt on a claim made in 1996 that 3.85 billion-year-old carbon found in rocks on Akilia Island (off the southwest coast of Greenland) had a biological origin. A geochemist announced at the 6/11/04 Goldschmidt Geochemistry conference that he could not replicate the original study. His work confirms research done in 2002 that showed the Akilia Island carbon could not be proven to be of a biological origin. This conclusion removes a serious origin-of-life anomaly in that the late heavy bombardment peaked at 3.85 billion years ago and took 60 million years to subside. This bombardment (of asteroid impacts) would not allow stable life to exist on Earth earlier than 3.80 billion years ago, which is identical to the date for the earliest undisputed evidence for life on Earth.
