Homo erectus and Homo habilis coexisted

So it seems that Homo habilis might not be the direct ancestor of Homo erectus, but instead a slightly earlier cousin that did manage to survive to living contemporaneously. This is being based off a Homo habilis skull that is dated relatively recently for that species, 1.44 million years ago, and dwelled in the same territory of Africa as Homo erectus.

I'm kinda excited, as i'm sympathetic to this theory. I'm also hoping for dates pushing backthe first appearance of Homo erectus.
