When Rodents Rafted Across the Ocean

The video explores the fascinating journey of caviomorph rodents, including capybaras, from their origins in South America to their migration across the Atlantic Ocean. It discusses the evidence supporting the theory that these rodents traveled from Africa to South America on floating plant debris, a process known as sweepstakes colonization. The video also highlights the diversity and adaptation of caviomorphs in their new environment, supported by fossil evidence and modern observations.
