“Cro-Magnon” doesn’t mean a separate species — it refers to the earliest European Homo sapiens (around 40k–10k years ago)."
How did they get the age of these species if they date carbon. How can cell tissue in dinosaur fossils still be found dated millions of years old. Determining rocks, how do you know how much chemical decay occurred unless you know how much it started with, and conditions under which it remained. Two sides of the same coin perhaps.
