I learned that two sexual organisms are considered different species when no two organisms having their respective DNA structures could interbreed to produce viable offspring. Put another way, when looking it up, I find the definition:
(a) Neanderthal interbred with homo sapiens to give part of today's modern man
(b) Neanderthals is a different species from homo sapiens.
Hence, the above definitions don't seem to hold. Can someone correct these definitions in light of this?
But then I read that:A single evolutionary lineage of organisms within which genes can be shared, and that maintains its integrity with respect to other lineages through both time and space.
(a) Neanderthal interbred with homo sapiens to give part of today's modern man
(b) Neanderthals is a different species from homo sapiens.
Hence, the above definitions don't seem to hold. Can someone correct these definitions in light of this?
