The interiors of giant planets remain poorly understood. Even for the planets in the Solar System, difficulties in observation lead to large uncertainties in the properties of planetary cores. Exoplanets that have undergone rare evolutionary processes provide a route to understanding planetary interiors. Planets found in and near the typically barren hot-Neptune '
Observations of TOI-849b reveal a radius smaller than Neptune'
Evolutionary-tree diagrams, which show the branching relationships between species, are widely used to estimate the rates at which new species arise and existing ones become extinct. New work casts doubt on this approach.
