A new development on the Neanderthal Man has been done. The first really complete skeleton has been put together and it shows some differences not expected. The rib cage is much bigger. And the physical strength is believed to have been much stronger. The article referred to Neanderthal Man as a different species, but definitely human. The average brain size given was actually larger than modern homo spaiens. The Neanderthals co-exist with modern homo sapiens for several thousand years according to this study. This was an article on MSN Home Page one day this past week. Pictures and all. SO, COULD AND DID NEANDERTHALS MATE WITH MODERN HOMO SAPIENS AND PRODUCE CHILDREN? Lots of different theories by reputable scientiests.
