Dunbar and Wiessner tell us nothing strikingly new, but they artfully tie together several strands of old evidence towards a deeper understanding of the development at the beginning of becoming human.
Looking at Boëda et al. I see several caveats. All the supposed tools were found near the tops of gravel layers of similar grain sizes. During excavation the fine grained layers are carefully scraped away, so it is the top of any gravel layer that emerges prominently and catches the eye. Lower down the need to remove stones leaves an irregular surface, where Read the rest of this entry »

On Friday I went to pay a shiva call (comfort the mourners) to the parents, brothers, sister and especially – the pregnant widow and orphans of Netanel Arami, may G-d avenge his blood. Netanel plunged to his death on Tuesday when somebody cut the rope from which he was rappelling as part of his work at a construction site. Read the rest of this entry »
Sher et al. use LOWESS to draw regression lines through extremely noisy data. They then go on to interpret those in far more detail than the data warrant. Their single limited sample makes it impossible to distinguish between true age-related changes and random, individual idiosyncrasies. I accept all their first-order results (none of which are new or surprising), but Read the rest of this entry »
Als sarkastisch-rhetorische Fragen, die nicht wirklich auf eine sachliche Antwort abzielten, wurden diese drei von der Moderation bei abgeordnetenwatch.de zu recht abgelehnt. In einer Zeit, in der Parteienverbote die Unfähigkeit zu inhaltlicher Auseinandersetzung kaschieren sollen, muß aber wenigstens hier auf Verfassungsfeinde und das Recht brechende Wiederholungstäter in hohen Staatsämtern hingewiesen werden.
Marshall has obvious implications for the continual attempts to sever even one- and two-year-olds from their mothers and offload them to state run institutions for most of the day.
The more we come to know about mother’s milk, as in Gura, the more valuable it gets and less easy to substitute.

It is amazing how the Israeli media ignored the tenth anniversary of the Oslo Accords. One would think that the media, always looking for hot topics, would not be able to get out of summarizing and analyzing the significance of the horrifying decade Read the rest of this entry »
Perry et al. offer another proof, that the characteristic physiognomy of African pygmies is adaptive and highly selected for. One question I don’t know the answer to and haven’t seen discussed so far, is how much the climate and environment on the island of Flores is similar to Africa’s tropical rain forest and induces the same selection pressure.
Although the reaction itself is exothermic, ammonia synthesis through the Haber-Bosch-process consumes huge amounts of energy worldwide and the generation of its hydrogen feedstock even more so. Licht et al. have found a way to combine the two and use the enthalpy of the synthesis to partially offset that of splitting water. Contrary to steam reformation the process itself does not generate carbon dioxide Read the rest of this entry »
