Leonardo’s paternal grandmother was Olga Anne Jacobs (the daughter of Paul Jacobs and Bertha Ludwig).
Leonardo’s grandmother Olga was a German immigrant.
So, I’m going to stick my neck out and use the 13,000 year BC date as the probable date of domestication. Dogs also come from a bottleneck, they’ve also been genetically separate from wolves for 100,000 years, and they’ve also undergone different environmental pressures than their wolf counterparts.
Just as the northern latitudes presented a unique environment for non-Blacks to grow up in, dogs were domesticated and evolved towards suiting human needs instead of wolf needs.
Forty thousand years ago, the Caucasoid race broke off from the Mongoloid race.
This means the entire world outside of Africa is largely related, descended from one small tribe of perhaps a few hundred or a thousand.
100,000 years ago, a small group of Africans had a sudden urge to head north.
This small group inhabited the rest of the world, with minimal contact with the rest of the Africans who stayed in Africa.He is the son of Irmelin (Indenbirken), a legal secretary, and George Di Caprio, a comic book writer and distributor.His father is of half Italian and half German ancestry, while his mother, a German immigrant, is of German and Russian descent.100,000 years under dramatically different environments from a dramatically different founding stock is a long time.Compare it to dogs: Dog Domestication and History “Dog history has been studied recently using mitochondrial DNA, which suggests that wolves and dogs split into different species around 100,000 years ago…” Another recent study suggests that the entire population of dogs today are descended from three females near China about 15,000 years ago.Also combined with light and simple diets and “Qi” gong exercises, the result is great and she is grateful that with the scientific and alternative homeopathy natural healing way has saved her life and the breast too.
