How long have freshwater bass existed?

Freshwater bass, particularly species like the largemouth bass (Micropterus salmoides) and smallmouth bass (Micropterus dolomieu), have existed for millions of years. Fossil evidence suggests that their ancestors date back to the Eocene epoch, around 40-50 million years ago. Over time, they have evolved and diversified into the various species we see today. Their adaptability has allowed them to thrive in a wide range of freshwater habitats.
