Why did so many alphabets show evidence that they emerged from the proto-Canaanite alphabet rather than each society showing evidence of a completely unique alphabet?

The correct answer to this open question is the following.

Many alphabets show evidence that they emerged from the proto-Canaanite alphabet rather than each society showing evidence of a completely unique alphabet in that historians consider this alphabet to be the ancestor of the Phoenician alphabet and the scripts of ancient South Arabia. Historians agree that the Canaanites were the ones that interpreted and reconstructed parts of the ancestral Proto-Semitic language used in the Bronze Age.

Experts in linguistics have studied the symbols and scripts and have found similarities with Phoenicians, Crete scripts, and Egyptian hieroglyphs.
