This is exactly why most scientists are almost as useless as faith people.
They just say something based on a theory.
Educated guess doesn´t seem better in my eyes.
I mean don´t say anything unless you have something that really is pointing to true facts!
And if this creature is an ancestor to our ancestors then it isn´t really a missing link directly to humans now is it?
It still deosn´t prove much of the human origin as it is today.
