no but if you chopped his head off his body would walk over pick it up and reattach it… dumb i Know but thats the beauty of comics.
Don’t think that’s quite the case – back around the Onslaught saga time there were the Xavier protocols, where Professor X had documented how to kill each member of the X-Men (in case they went evil). Wolverine’s method was to decapitate him and remove his head from being anywhere near its body, as it would reattach if it was left close enough.
But as already mentioned, it varies massively according to who’s writing him. They did go through a phase where they tried to make out that he wasn’t a standard mutant, but instead belonged to another branch of humanity, descended from wolves instead of apes (as were Wildchild and Sabretooth). However, much like “Nightcrawler’s dad was a demon” and “Angel is banging a 16 year old”, subsequent writers retconned it out.
