Cameron, A.G.W., 1963: The origin of the atmospheres of Venus and the Earth. Icarus, 2, 249-257, doi:10.1016/0019-1035(63)90021-6.

Evidence regarding the Earth's atmosphere is reviewed and it is concluded that there are no detectable traces of the primitive solar nebula surviving in it. Evidence concerning the Venus atmosphere is analyzed and it is concluded that it probably contains of the order of 100 times the amount of nitrogen in the Earth's atmosphere and negligible amounts of water vapor. It is very difficult to see how the two atmospheres can have had a common origin, and it is proposed that the bulk of the Venus atmosphere is a remnant of of the primitive solar nebula. In order to account for the absence of primitive gases from the Earth's atmosphere, a modified form of the Darwin-Wise hypothesis is proposed, according to which the Moon is formed as a result of the Earth's rotational instability induced by formation of the iron core. During such rotational instability the primitive gases would be entirely lost. A discussion is given of the circumstances surrounding the period of rotational instability.
