Comment on "Does the rapid appearence of life on Earth suggest that life is
common in the Universe"
Authors: V.V. Flambaum
Comments: 2 pages, RevTex
In a recent paper [1] Lineweaver and Davis performed a statistical
analysis to claim that the rapidity of biogenesis on Earth
indicates high probability of biogenesis on terrestrial- type
planets. We argue that the rapid appearance of life on Earth
hardly tells us anything about the probability of life to appear
on other planet. The conclusion should be different. The rapid
initial biogenesis is consistent with a large number ($N \sim 10$)
of crucial steps in evolution from simplest life forms to humans.
