In our woolliest episode ever, Claire tells the tale of the woolly mammoth and new research on the last known individual, called Lonely Boy; and coincidentally Chris excavates a new study on the population dynamics of the woolly rhinoceros, and its extinction from climate change and human hunting.Dehasque et al. 2024. Temporal dynamics of woolly mammoth genome erosion prior to extinction. https://doi.org/10.1016/j.cell.2024.05.033Fordham et al. 2024. 52,000 years of woolly rhinoceros population dynamics reveal extinction mechanisms. https://doi.org/10.1073/pnas.2316419121
