i mean thats what's biologically interesting about them, that two things that look very different are simply a hormonal response to two environments in the same animal. but all the feral hogs (in the americas) are escaped domestic hogs.
if anything an offspring of feral stock from an older lineage with a modern bigger one would produce a smaller hog
They literally change physically when they escape, growing bristles and tusks
Also generation upon generation of breeding especially for size and lean muscle mass will have an effect on the gene pool
