No, it hasn't. “Private property”, in the sense in which it is a defining institution of capitalism (ownership of the means of production by an individual as marketable property distinct from. ownership of or personal jurisdiction over land), requires the conceptual separation of individual property and public authority that is one of the characteristic features of the transition from pre-capitalist (specifically feudal in most of the West) to capitalist property relations. It is not something that universally existed from prehistoric times. You seem to be confusing the particular sense of “private property” associated with capitalism with the more generic concept of individual property, which is necessary to capitalism but not distinctly capitalist.
Modern capitalism's private property is based on exactly the same principle of exclusive control over a mass of matter as pre-modern society's private property. It is a more sophisticated version of it, that incorporates the advances of modern civilization to its enforcement and utilization, but that is to be expected with any institution as it evolves with the times.

I don't know what this means. Can you elaborate?
The term "personal property" is mostly used by Marxists.
Now to your point: private property intended for personal use, which socialist ideology claims is not problematic, is the direct progenitor of private property used for other purposes, like earning an income for the owner from being rented out, or from being utilized in an enterprise that employs other people to operate the private property.
The differences between private property intended for personal use, and private property intended for business or commercial use, are completely superficial with respect to the basic principles that society operates on.
Returning to humans, extant hunter gatherer groups observe property rights, both at a personal level, with their ownership of tools and clothes:

>>Moveable material property, such as tools, clothing, and valuables, is generally treated as individual property
And on the inter-tribal level, with tribes asserting exclusive control over the territory that they exploit.
Food sharing is common in hunterer gatherer societies, but almost all of it is intra-tribal, meaning to relatively close kin. Even within the tribe, such sharing is heavily biased by kin selection.
Food sharing is often very reciprocal as well, with an expectation of a return in exchange for the 'gift'. This is also demonstrated to some extent experimentally:
