Final conditions (after 4.5 Gyr) for all evolutions that reproduce Venus in a space defined by five parameters: the final temperature of the upper mantle, the final thickness of the crust, the final heat flux at the surface, the fraction of the core that ends up solid (RIC), and the final eruption rate. Each simulation is color-coded based on the identified evolutionary scenario as described in the text. The histograms show the distribution of all simulations marginalized over all variables except for each variable below them (or to the left). Note that Type II evolutions (the blue points) carve out a very distinctive region in any subspace containing the heat flux at the surface or the eruption rate, and Type III evolutions (red points) carve out a distinctive region in any subspace containing the fraction of the core frozen.
