What would happen if you left canaries alone on a world to evolve for hundreds of millions of years? This is a breakdown of Dylan Bajda’s speculative evolution epic ‘Serina.’ Imagine what could happen if you left a type of bird — for example… finches — alone on a lush planet without predators for hundreds of millions of years. What kinds of incredible forms might evolve? If you consider that mammals grew from a few rodent-like species into elephants, whales, horses, bats, and primates in a much shorter period after the extinction of dinosaurs — you’ll start to realize just how incredible things might get.
