Southam et al. today. Also, since it is a rocky planet, it is expected to have possessed many of the geochemical, redox conditions and processes that were favourable to an origin of life on Earth during the Hadean–Archaean. Therefore, we would have to consider it to have been habitable at this time and perhaps, even conducive to an origin of life. A potential problem with an origin on Venus could have been the acidification of it’s hydrosphere. Organic carbon macromolecules, the building blocks of cells, are less stable under acidic conditions.
