Giraffes are hard to miss. Scraping the sky at roughly 5.5m up, they are the tallest animals on Earth. Humans have taken notice, becoming infatuated with giraffes from the first moments of the animals' lives, and revering their iconic, alien gangliness across the globe. But despite all this attention, our species doesn't have a particularly good grasp of the evolutionary history of giraffes and their relatives. But now, thanks to a newly-discovered fossil of a new species of extinct, ancestral giraffe, the giraffe family tree just grew a few more limbs and came into tighter focus.
