You are absolutely correct. It took time for the evidence to be reviewed, accepted, and for the new consensus to be codified. Mostly, I wanted to let folks know the headline was a bit click-baity and give some examples of how we got here. I wish we were wired to get the same excitement from titles like, “Zoologists agree: Giraffe are four species – not just one!” with an article that gives more credit to all the research.
