~ DNA sequencing is an extremely important tool in the fields of Genetics and Molecular Biology.
~ The Human Genome sequence was finished in 2001. That is 3,000,000,000 bits of information were decoded and put in order – a BIG job.
~ Now, using 38,000-year-old bone fragments, researchers have sequenced 3.7 billion base pairs of Neanderthal DNA.
~ Neanderthals are our closest relatives on the hominid family tree. We split from them about 500,000 years ago and for the next 475,000 years or so, modern humans and Neanderthals coexisted on the planet and sometimes even in the same region.
~ Neanderthals vanished about 30,000 years ago, leaving modern humans to inherit the Earth. Why humans ended up being more successful has long been a topic of debate.
~ Interestingly, the newly completed sequence shows that humans and Neanderthals have genomes that are 99.5 percent the same.
~ By comparing the human and Neanderthal genomes with that of our closest living relative, the chimpanzee, researchers hope to tell which genes changed very recently, giving modern humans an edge.
some think the rh – was an adaption to colder climate . this is due to a different co2 gradient in cold air . the rh+ cell respiration channels were less needed and began to dissapear so rh- began to form ? the ice ages had profound effects on global climatictics . rh – = cold weather adaption. this is why its more in the north of europe .
Thank you for the info. I will research more in depth
Has anyone ever thought that Neanderthal DNA came from star dust, not monkeys.
Aren’t all living things made from Carbon, Hydrogen, Oxygen, Iron, Calcium, etc?
Have they actually named the rh neg gene in the sequence? That would be interesting to see them post that info.
Aggression and war like behaviour gave Cro-magnons the edge. However some of us still do have Neanderthal DNA, so we never died out.
