No, radiometric dating is not used to determine what species bones come from. There is a whole science dedicated to bones. These people can look at a set of bones and tell you if they were male or female, if female, whether they had birthed babies or not, and a whole bunch of further things...just from looking at the bones.<quoted text>Furthermore, you also talked about neanderthals!
Now tell me, those fossils or bones discovered, how did you guys knew/ know it is a bone/ fossil belonging to the neanderthals?
Who made that? Humans? Are humans perfect? No.
Please, Buddy, science has its own limitations.
Neanderthal bones are larger (diameter) and stronger, but shorter than the average Homo-sapiens. The skull is different in may ways and the brain pan is larger and held a bigger brain than humans and of course the DNA is different....much more different than the spread of DNA that modern humans carry around.
