Human Neanderthal Hybrid Update

Apparently the documentary I saw was belated or a rerun. Did a little digging and found out that the bones were found in Portugal near the coast north of Lisbon. It was a skeleton of a four-year-old boy with features of modern human but limbs proportionately Neanderthal. Research from DNA tests found links of modern human with Cro-Magnon but no apparent link with Neanderthal. Don't know if it's possible that their DNA 'disappear' with interbreeding or they just evolved and 'became' modern human hence the lack of trace of DNA. Just my wild imagination.

Human Neanderthal Hybrid

Saw a documentary at Discovery. They found some bones which they thought was human but later found out that the arms and legs were not proportionately human. It doesn't seem mind boggling for humans to interbreed with Neanderthals. Hopefully they will find out the answer soon. Heard they are doing some DNA tests and researching.
