Well, genetically all humans can be traced by mitochondrial DNA to one mother, one (1), whom they, they, call "Eve". Interesting, no? First, apes are apes, whatever species. Some of these alleged preview or humans are claimed to exist by a single piece of broken skull. As one trained in the laws of evidence, this is paltry and wishes other than evidence. Do you consider the Neanderthals as humans ? well, of course they were, though they were considered once as precursor humans by evolutionists. They also were considered not to be able to speak, which we now know was dead wrong. They were human beings who interbred with other human beings, your DNA will show what percentage of theirs makes up yours
Not true on several levels.
Not a single piece but many thousands of single pieces of bone fragments have been analysed spanning 500,000 years.
It has been known that Neanderthal and Sapiens lived in the same overlapping time period, the only people I've seen claiming they were precursor humans are creationists attempting to bridge the dinosaur/ human gap
Neanderthals were not human but homo Neanderthalis, humans are homo Sapiens, recent research (The Nasal Complex of Neanderthals: An Entry Portal to their Place in Human Ancestry) shows they were not human.
Several Neanderthal hyoid bones have been examined and shown to be comparable with speech and positioned in the throat similarly to humans. This is not a guarantee that they could speak but a strong indicator. Basically science does not know, so please provide citation for your claim that "They also were considered not to be able to speak, which we now know was dead wrong."
