Science has lost two great ones: Jenny Clack and Robert L. Carroll. Clack was an expert on the evolution of tetrapods, as was Carroll, who also studied reptile evolution. Normally, I’d be sitting my office right now and would be able to lift my eyes to my bookshelf and see Gaining Ground: The Origin and Evolution of Tetrapods and Patterns and Processes of Vertebrate Evolution, and re-reading them would be the best way to honor these influential scientists, but I’m stuck at home like many of us, so I’ll have to wait until I can fetch them.
