Here is a possible explanation. Modern man did come from a common ancestor with the chiemp. Some of these early humans escaped Africa and made it to The Mid-East, Europe, and Asia where they encountered other races of man and interbred. Neanderthal and Denisovan come to mind. Meanwhile back in Africa saying goodbye was hard to do and breeding across the line went on for a while after the wanderers had left for Eurasia. Modern man for whatever reason dominated the other races of man found in Eurasia and they were absorbed. But in a very similar way to hybrid cattle they exceeded the parent breeds much as does most any F1 cross. In the south a Brahman cross with a European breed is usually a better animal that either of the original pure bloods.
Sub Saharans have no Neanderthal blood and other than maybe Australian Aborigine have the smaller brains of the human races.
In any case we are all human and therefore similar in many if not most ways and have proven the ability to breed across the racial sub species lines. Many of the same maladies and diseases affect all humans and some are race specific or at least race dominant.
As to the cattle comparison. While they are all cattle and can breed and produce offspring there are traits that are race specific or more often race dominant, such as the excitability of the Brahman breed, the gentleness and milking ability of the Jersey and so on.
So yes all of us are God's children and all are human but some of the races are more amenable to civilized life and don't go around like a tribe of chiemps seeking a rival group to kill.
LOL. And some don’t fight over waffles and crab legs at the local restaurant. 🤪
