Your question is actually far more difficult to answer than it first appears. The definition of a species, at least to many biologists, is a group of organisms that cannot reproduce with any other group to produce viable offspring. Clearly, an oak tree and humans are different species. However its difficult to say whether some officially distinct species can or cannot reproduce. Humans can't reproduce with oak trees for purely mechanical reasons - our sperm won't fertilize their "eggs", or vice versa. And in the wild (most of the time), lions simply will not mate with tigers, but in a zoo they will, producing a liger. So are they different species in the wild but not in captivity?
