Humanity
Even your evolutionist colleagues would deny that the fossil records do not show humans.
Hey, if that’s so then I ought to be pretty easy to embarrass here. The oldest known fossils I’ve heard of are 195,000 years old. Where can I read about human fossils that are older?
Bone for each found in the appropriate time frame and that time frame only. Enjoy.
Are you claiming each chip or collection of bones found in a rock dated indirectly (and ignoring fossil displacement) evidences a new species?
Yup. They display traits not found in modern humans.
The fossils are individuals, not groups. How do you know that none in the group could successfully interbreed?
How do you know they could?
Speciation seems to take between 4k to 25k generations, depending on the pressure. The time frame is certainly right.
If the rock dating is correct and longer than the estimated life span of the individual (unknowable) then the most one can conclude is the individual most likely could not make the attempt to interbreed. That is not the same as could not interbreed.
On this basis, I guess we don’t know for certain if humans could interbreed with Tyrannosaurs, lol
No, I don’t think it asks what explains accidental characteristic differences but essential differences, like the ability to successfully interbreed. So, I ask you again: What species is Neanderthal?
Homo Neanderthalensis, easy enough.
Science answers the questions: “Who and How and Where?” The “Why” question is a teleological question and outside the range of scientific inquire. Your avatar, the quintessential empiricist, would protest vehemently.
Then
Where are the human remains that co-date with tyrannosaurs? I mean, we have difficulty finding any older than 195,000 years old, much less 65,000,000 years old.
I mean,
surely we’d have found one stinkin’ bone!
Not gonna let you dodge this one.
