wonderful! I always thought, that the neanderthal tool of 23andme is complete nonsense and am very glad to hear that sceptical voice. While some, like Dienekes in his latest blog entry are about to pinpoint the exact date of interbreeding, it is really time for such a critical note, even if nothing is prooved until now!

well, he is reflecting now:

what the past 156 years of Neanderthal perception shows, is the fact, that they are allowed to come nearer and nearer. A few years ago divergence time for our last MRCA was considered at about 600000 bp due to the old estimation of mtdna mutation rate of 20000 years. This has changed and in the above article it has shrinked to 300000 kybp. Perhaps we have not yet reached the final split.

I often asked myself, wether they could have spoken a sort of click language like the San or the Hadzabe.

Ancient Mariners: Did Neanderthals Sail to Mediterranean?
Source (http://www.livescience.com/24810-neanderthals-sailed-mediterranean.html): http://www.livescience.com/24810-neanderthals-sailed-mediterranean.html

Excerpt:

Neanderthal sailors?

For instance, obsidian from the Aegean island of Melos was uncovered at the mainland Greek coastal site of Franchthi cave in layers that were about 11,000 years old, while excavations on the southern coast of Cyprus revealed stone artifacts about 12,000 years old.

"We found evidence that human hunters may have helped drive pygmy hippos to extinction on Cyprus about 12,000 years ago," Simmons said. "This suggests that seafarers didn't need to have already domesticated plants and animals to go to these islands, which is a pretty complex set of tricks — they could have been hunter-gatherers."

Recently, research has hinted that seafarers may have made their way out to the Mediterranean islands even earlier, long before the Neolithic, and not only to isles close to the mainland, but to more distant ones as well, such as Crete.

For instance, stone artifacts on the southern Ionian Islands hint at human sites there as early as 110,000 years ago. Investigators have also recovered quartz hand-axs, three-sided picks and stone cleavers from Crete that may date back about 170,000 years ago. The distance of Crete about 100 miles (160 kilometers) from the mainland would have made such a sea voyage no small feat.

The exceedingly old age of these artifacts suggests the seafarers who made them might not even been modern humans, who originated between 100,000 and 200,000 years ago. Instead, they might have been Neanderthals or perhaps even Homo erectus.

"The whole idea of seafaring makes these extinct groups seem more human — they were going out to sea to explore places that were uninhabited," Simmons told LiveScience.

Our Hands Evolved for Punching, Not Just Dexterity

Our Hands Evolved for Punching, Not Just Dexterity
http://www.sciencedaily.com/releases/2012/12/121219223158.htm

I have to say I'm surprised by this. I've always heard that fists aren't the natural way of fighting (as opposed to hammerfists, open palm strikes, wrestling, etc.). It's very common to suffer hand injuries from fighting closed-fisted, actually. I have to read the study (and not just the article) more thoroughly, but it's an intriguing concept.

They're using the increased dexterity and length of the thumb as the focal point of this theory, from reading the blurb.

I'm not an orthopaedic consultant or a physical anthropologist, but I would've thought our wrist (carpal) bones would have become far more durable than what they currently are. Scaphoid bone fractures are surprisingly common clinically.

Then again, perhaps this is another example of "in the works" evolution. Much like the level of injury commonly seen in human knees. A trait develops, but it isn't without its' own drawbacks.

A high-quality Neandertal genome sequence (http://www.eva.mpg.de/neandertal/index.html)


The genome sequence was generated from a toe bone discovered in Denisova Cave in southern Siberia in 2010. The bone is described in Mednikova (Ethnology & Anthropology of Eurasia 2011. 39: 129-138).

DNA sequences were generated on the Illumina HiSeq platform and constitute an average 50-fold coverage of the genome. 99.9% of the 1.7GB of uniquely mappable DNA sequences in the human genome are covered at least ten times. Contamination with modern human DNA, estimated from mitochondrial and nuclear DNA sequences, is around 1%.

The figure shows a tree relating this genome to the genomes of Neandertals from Croatia, from Germany and from the Caucasus as well as the Denisovan genome recovered from a finger bone excavated at Deniosva Cave. It shows that this individual is closely related to these other Neandertals. Thus, both Neandertals and Denisovans have inhabited this cave in southern Siberia, presumably at different times.
