A fragment of a long bone from a hominid at least 13 years old shows that it had a Denisovan father and Neanderthal mother. The specimen was found in Denisova Cave in Russia in 2012. Because it was found indicates that other cross breeding occurred. Neanderthals obviously migrated to eastern Eurasia from western Europe. They were not "stuck" in regions around the Iberian Peninsular. Genetic analysis shows that the father of the Neanderthal/Denisovan adolescent also had some Neanderthal ancestry, so the groups were coexisting in the east. It is believed by scientists that Neanderthals interbred with humans and had fertile young. However, this is not possible as Neanderthals have 24 pairs of chromosomes while humans have 23. Interbreeding of Denisovans and Neanderthals could occur as they both had 24 pairs of chromosomes. + so denisovan is neanderthal us dna ox humans a denisovans i fossil oh mother ah genes by mixed id years + ~ ha denisovan in neanderthal on dna an hum

Biology - 100 million unnamed species exist on the planet. We know that many species on the planet are dying out. Apparently, we have nothing to fear. Though 2 million species have been named, a massive 100 million more are out there. This does not include currently unnamed bacteria. Each living creature is placed in a species category because it has independent evolutionary lineage. A horse and donkey for example are different species, but they both have a common ancestor. If they do breed their offspring are infertile. There is debate about this with claims that some mules have had young. This gets into the argument about Neanderthals breeding with humans when they have a different number of chromosomes. Interbreeding should not be possible. Brewer's Sparrow The problem with naming is that animals from two species can look virtually identical. The African elephant is a misnomer. There are actually two species: the bush elephant and the forest elephant. One
