Dwarves are ‘different’ from ‘men’ as well, however according to all the tales not only they and humans can interbreed, but (rare/unlikely) dwarves and the elvenkind can interbreed as well.
You really should read the article more closely to see if the reality adjoins the fables in any way, or are we so different from them as from dogs and cats despite physical compositions?
Chimps and humans, anyone? *shudder!!!*
“You really should read the article more closely”
That would violate Freeper protocol.
