Giant Scorpion Discovery Challenges Scientific Understanding of Evolution

In a laboratory somewhere between the known and the unimaginable, scientists have encountered a scorpion the size of a coffee table — a creature whose very existence quietly dismantles decades of settled thinking about how large life with an exoskeleton can grow. The discovery, still being dated and traced to its origin, suggests that Earth's deep past harbored conditions generous enough to permit forms of life our current models have not made room for. It is a reminder, as such discoveries always are, that the boundaries we draw around the possible tend to say more about the limits of our kno
