How Old Are Squirrels Evolution, Their evolutionary journey Origins of Squirrels: Tracing Their Evolutionary Beginnings Let’s dig into where squirrels first showed up, which fossils matter most, and how the Sciuridae family branched into tree, You might be surprised to learn how ancient squirrels really are, and where they first appeared. The question, When did squirrels first appear on Earth?, leads us on a fascinating journey through geological epochs and evolutionary milestones. Following their initial emergence, squirrels experienced rapid evolutionary diversification coinciding with a major climatic shift about 36 million years ago. If you trace back, squirrel ancestors go all the way to the Eocene—about 34–53 million years ago. We trace their fossil origins, diversification into major subgroups, and how they spread globally. Diversification into Modern Squirrels: Over millions of years, squirrel lineages diversified, leading to the various species we see today. Explore their remarkable adaptations and survival strategies. These early Molecular studies further indicate that the five primary groups of squirrels, including flying squirrels, diverged during the late Eocene and Oligocene, roughly 34 to 23 million years ago. According to fossil records, the first squirrels arrived in Africa shortly after that former island continent collided with Eurasia about 18-20 million years ago, the Duke researchers said.
