Hobbits and prior Ages

Hey guys! Since Hobbits are a subrace/ethnicity/subspecies of Men, like the Beorning Skinchangers and the Druedain, did they evolve/show up only in later Ages of Men or did they first awaken with the rest of Men when the sun rose and by extension there with phenotypically "Hobbit" people amongst the Edain? By the same extension, what of the other ethnic groups of Men that have more supernatural abilities? Were there Skinchangers like Beorn amognst the Edain's hosts? If there's no source that says explicitly no, I'd imagine then they would. If so then we don't actually know for sure if any of the ancient Edain heroes were halfling Men, which is really funny. Like imagine if during the Dagor Dagorath how people would react to see 3 foot tall Turin slay the First Dark Lord lmao
