Homo Floresiensis' validity under question

Robert Eckhardt (professor of developmental genetics and evolutionary morphology at Pennsylvania State University) and the rest of his team are again questioning whether H. Floresiensis is actually a new genus.

They think the remains relate more closely to an early human group suffering from microcephaly.

I'm not so sure about this, because for every person or group saying it's a separate genus there's another one that disagrees. The idea is interesting nonetheless.
