Please cite this 3 million year old Homo.
Instead, what most seem to believe is that the evidence for
tool use can be associated with australopithecus.
This is secondary or indirect evidence, such as what is reported
to be cut marks.

This points out that Homo had far better vocal communication that Australopithecus, because Homo got Australopithecus extinct in Australopithecus' territory.

They appear to have not gone extinct and to instead have
survived until about 300k years ago AND LESS:
Naledi.
