I live in the United States, and I assume my cranium is comprised of eight bones. I also assume your cranium has the same number. Also the craniums of all the people who live in Ethiopia. Also the cranium of this supposed "missing link" that has tools strewn about its proximity.
Fester,
Would you like a list of the human cranial bones, taken from a human osteology handbook which I acquired from the local police CSI lab? Would you consider such a source (written by an osteologist and paleontologist and forensics man named Bass) as authoritative?
Sentient people assume that those who can't distinguish between 8 and 22 and who don't care to learn the difference have little to contribute in a discussion of science.
"I live in the United States, and I assume my cranium is comprised of eight bones."
So, you're not human?
"I also assume your cranium has the same number."
Nope, I'm human.
"Also the craniums of all the people who live in Ethiopia."
Why Ethiopia? Why pick them?
I assume you are trying to point out that only humans have 8 cranial bones because you believe this will verify that there is a sharp delineation somewhere in among the many fossils between our Pan-Homo common ancestor and Homo s. s. that will divide them in to two distinct groups?
If at that delineation point there are features other than the number of cranial bones that place the 'ape' in with 'Homo', which feature(s) takes precedence?
