The most damning misconception about dinosaurs is the idea that their extinction, except for the birds (more on that later), represents their own failure to adapt to changing conditions. Until relatively recently, the idea seemed patently true. If only they weren’t such dim-witted, sluggish, stuck-in-the-mud, ponderous creatures, maybe they could have survived and hung on to the domain that was once theirs. But they weren’t good enough. Not clever enough. Not adaptable, like our own tiny ancestors. And in the end, they couldn’t hack it, and the cream, like it always does, rose to the top. The mammals took over, and here we are, smarty-pants primates, with dominion over the Earth. That was the narrative.
