It happens all the time. There’s a limited number of ways to solve a problem, and nature will trend towards a certain optimum. That’s why we have wolves, and Tasmanian wolves, which are basically the same and yet completely unrelated. That’s why basically every culture has a form of canoo, and why there are marsupial and placental moles, or hummingbirds and sunbirds. And why American and African pyramids look roughly alike. Or why pretty much every culture has pottery, or fire.
