Then (Cro Magnon) and Now

DNA from a 28,000-year-old Cro-Magnon individual (found in the Paglicci cave in Italy) is identical to that of modern Europeans.
It implies no significant genetic change has occurred in that time span.
Larger Brain Capacity:
Suggests the Cro-Magnon had a larger brain than modern humans.
Rejection of “Out of Africa” Theory:
Asserts that certain haplogroups associated with Europeans (e.g., M14, P262, M32, M59) do not descend from African haplogroups A or B.
Implies that Europeans (referred to here as "Caucasoids" or "Europeoids") are genetically distinct from African lineages.
