Paleogene equatorial penguins challenge the proposed relationship between biogeography, diversity, and Cenozoic climate change

New penguin fossils from the Eocene of Peru force a reevaluation of previous hypotheses regarding the causal role of climate change in penguin evolution. Repeatedly it has been proposed that penguins originated in high southern latitudes and arrived at equatorial regions relatively recently (e.g., 4...
