    Interstellar (pretends to be scientifically enhanced or so): - a ship falling away from another one while both are under zero acceleration. And of course the whole thing "hybernation". But needed for the story to work ... - a chemical reaction in a higher vertebrate's body (called love) as a cause for effects between different galaxies ? Even midichlorians are restricted to a galaxy far far away ... :-) Nevertheless i liked the movie as a scifi movie. Europa Report: I wouldn't let those derks go hiking alone on the mountain here. They would kill themselves one after the other, falling in crevasses, slipping on loose rocks, an so on. A movie i could hardly watch to the end, because after 10 minutes it was clear how this would go out. Iron Sky: Cool crap. The giant eccentric, smartphone controlling a ship, slight reference to politics, greatcoats, stereotypical characters ... it's a cultural highlight The Marsian: We know the weaknesses, i would add nutrition and survivability/loss of strength as well as direction controlling during uncontrolled propulsion by loss of pressure to the inconsistencies (the ship as well as mark would probably just do the deflating balloon), but still a nice movie. I haven't watched the other ones mentioned here (except of course Star Trek and Wars) ...

    The description of the Feldhofer specimen is from Prof. Herrmann Schaaffhausen, University of Bonn, Fuhlrott was a local scolar who identified the bones as significant, translated them to Schaaffhausen and participated in the analysis. The "tribe of the flathead" ("gehört ... zum Geschlechte der Flachköpfe") is from a newspaper journalist and was published without the approval of Fuhlrott or Schaaffhausen(*). This is important to correct as it sheds a wrong light on the descriptions and it is incorrect to attribute these words to Fuhlrott. I dont have the time for a full analysis, too many words. (*) https://de.wikipedia.org/wiki/Neandertal_1 It may be a problem that almost all original literature on neandertals is in German or French ... Edit, ok ... ... i mean, if you want to question the dating and methods of the finds in Gibraltar, why not contact Finlayson ? If you address him courteously he'll surely share his knowledge with you. For the modern excavations in the remains of the Feldhofer cave, Ralf Schmitz is the right one. I know him well, he is a nice guy and an incredible source of information on everything Neandertal.

    If you add 1cm to the radius of a 10cm circle, its circumference increases by ~6.3cm. If you add 1cm to the earth's radius, its circumference increases by ~6.3cm. Ok, that was trivial. But that's not why i am here ... what was it ... ah ! Hydrodynamic simulation of the universe in new quality: http://www.mpa-garching.mpg.de/515751/news20180131 From: http://www.tng-project.org/ I find it cool.

    That depends on what is divided, the representation of the number, and the algorithm. For integers: if it does multiple subtractions then nothing happens. If it does shift operations (division by 2) then nothing happens. For floating point one could multiply by the reciprocal of the denominator, which would result to 0. There are other approaches for fast algorithms, but in the end it boils down to if the compiler or assembler or interpreter or runtime environment or whoever is responsible doesn't spit out an error weird things will happen. But i am not a specialist :-)

    What a silly mistake, if it is correct. Sounds like too much confidence and routine ...

    Humans: i can't help define "real speech". The "cognitive revolution" was largely a fashion several decades ago. We rather distinguish abilities of the current modern humans by "behavioural modernity", which shows up a little abruptly about 40ky ago. That's probably what you mean ? If it is connected to language ? Maybe gradually, that language become more sophisticated than before ... As to the early evolution of language ... that's a problem that is difficult to solve. More complex sound making might be as old as late erectusses / ante-neandertals like heidelbergensis, with a narrower range of sounds and less vocalisation than that of today. Let's say, not Latin, but English . Seriously, anatomical abilities play a role of course (nerv-canals in bones, hyoid bone, ... can serve as hints), some have tried to read in the genes (try foxp2 for a search), it is not clear.

    It is a little more. Social learning goes in the direction that different or new behaviour can be acquired. In how far that goes in a specific species or individuals of a species depends ... as the previous writer said: not enough info yet. People living or working with animals that have natural social abilities "built in" frequently observe copying (e. g. apes) and simple communication abilities.
  8. Green Baron
    Imitating sounds ... natural social learning capacity. Nice :-) If i remember correctly, orcas hunt socially.

    @James Kerman, have fun ! Greetings from the other (wrong) side of the disk :-)

    Great care must be taken when working with ancient DNA. The first take on the neandertal genome by Pääbo et al. braught to light that neandertal and anatomically modern humans did not interbreed. At a time when the contrary was long clear to archaeology. It took them two years to change their mind, based on the same set of samples. The Denisovian (i say neandertals just for provocation) are based on a single site and 4 fragments, a finger fragment and 3 teeth. It is not completely silly to wait for the analysis to crumble as new data comes in. Don't get me wrong, i have no problem with ancient DNA, but it is not as safe as it may sound. By far not. It can add a mosaic part to the greater picture that comes together from physical, chemical, geographical, archaeological, sedimentary, palynological, climatological, anatomical and typological data gained from all sources at hand.

    Keyboard archaeology: Like the Milankovic cycles on earth a keyboard goes through a daily, weekly and yearly cycle, building up corresponding strata of residuals. We shouldn't destroy this cultural heritage ....

    That was what i meant. Maybe i hit the wrong expression. Nevermind :-)
  14. Green Baron
    I take this as a yes to the first and a no to the second part and can go to bed with a calm conscience. :-)
  15. Green Baron
    Can't you do this with any blowtorch ?
  16. Green Baron
    But you agree that the Jebel Faya stone tools are typical for modern humans, that these came rather out of Africa then from anywhere else, and the dating of the sediments is credible ? Furthermore you don't accuse the guys of messing things up ? Edit: tagging @PB666 because my two lines might get lost between the walls of text :-)

    Man, indeed, so i read, Sir Rod Stewart is a model raidroader. That is really cool :-)

    The rocrail tip was was good ! It works, though with a trick i mentioned already (giving write access to /dev/ttyUSB0). This must be done after the control unit is plugged in and switched on, before the program is started and isn't mentioned in the installation hints. This is beautiful railroad you guys are doing !

    More special transport, car set "Windmill": I have the electronics running. Now to a little woodwork. And i found a model making shop that sells train stuff, fortunately on the neighbour island. *phew* :-)

    "Largely false" most probably not. It is already based on 2 generations of research. I don't want to lecture anybody :-) But the dates may shift farther in the past, most likely not into the future as most dates are already lower limits. But, of course, a scientist can never categorically exclude a future development :-) Now this depends: the physical part like sediment analyses, physical dating, ... is of course based on experiments and observation. In the case of stone tool ensembles, the techniques and methods themselves are of course experimentally reproducible and reproduced. To combine an ensemble with a specific human type requires a walk around one corner, namely the comparison to other, known findings. That isn't true. Everybody is aware. If there were serious doubts, we'd discuss them. Doubts may show up in the future, then we discuss them. Be sure i'll post it here as soon as i get knowledge, if the forum is still running, i am still alive and the thread wasn't closed :-) Now that could be understood personal and is not a helpful comment, i hope it wasn't meant so !

    I like to keep in concrete, focused and on topic. The publications i and for example @tater and @James Kerman linked are all agreed on, as far as the current state of research permits. There always is room for improvement, naturally, but the working principles and their application to the reality of findings is based on a broad consensus, there is nothing abstruse in it to scoff at. Peace, brother :-) Edit: if i may add and to clarify, a work like that on Jebel Faya, which at its time was the earliest find attributed to modern humans outside Africa, is not written by a single person in a candle lit upstairs room. Several institutions in different universities and research institutes work together, giving out bachelor/master/phd theses on climate reconstruction, stone tool analysis and comparison, physical dating methods etc. pp. Of the list of authors, several have their own chair as a professor or are retired meanwhile. These people talk and compare, present and meet on conventions, etc. before they come out. That's why it takes several years from the find to the culmination in a science or nature paper.

    I don't. Because i have studied it. Stone tools were my specialty. And i have not seen a single well grounded scientific comment doubting the logic. You are alone :-) Which does not mean that it is the last word. A source would be nice. " As Green Baron notes the ability to produce stone and shell culture is not something unique to OoA crowd. " I did not say that, though it is trivial. But what i say is that the ensemble presented from the Jebel Faya Team (whom i was a member of for a short time as a student) are typical for African middle stone age and there is absolutely no brain gym necessary to connect it to modern humans until recently. Africa is different than Europe. And the work combines geography, climate reconstruction, classic Archaeology and physical dating. --------- We will never come to an agreement there. I insist in sticking to the main stream, an encompassing approach that includes fossils, stone tools, sediment samples, palynology, pollen, charcoal, climate, physical dating, landscape reconstruction as far as possible and reasonably applicable. Because these give us a comprehensive and broad approach to the goal of when, who and where. Where there is contradiction it must be described, consensus add to the picture. -------- Hope that's okay. Now, have the last word, don't get personal, and then lets move on, ok ?

    I think it'll become more and more difficult to keep that single group argument if more places are found. It is difficult to define specific adaptations >45,000 before now because the tools and technologies are rather homogeneous, only with few exceptions. A great variety (in Europe) shows up all at once with the moving in of modern humans (blade technology of the Aurignacien, bone tools dedicated to clothing, composite tools). The latter two where known to the Neandertals in Europe as well at least since late ois 5 (find site Königsaue), probably much earlier. https://www.sciencedirect.com/science/article/pii/S0305440312000969 But i know almost nothing about the conditions in Australia. It is absolutely ok to expect that early modern humans were able to survive in adverse conditions. I can say from experience that dry and heat is challenging, people should watch each other or the inexperienced drink too little, overheat and start to talk and do nonsense :-)

    Pop science articles interpreting the Jebel Faya i linked above, which is about modern humans out of Africa on the southern route between ois 6 and 5, probably at the end of 6 around 125,000 years bp. Here's something: https://www.livescience.com/11651-ancient-arabian-artifacts-rewrite-oout-africao-story.html Jebel Faya has a Wikipedia page i see. Wikipedia, *sigh* :-) https://news.nationalgeographic.com/news/2011/01/110127-out-of-africa-earlier-early-humans-left-science-climate-stone-tools/ https://www.scientificamerican.com/article/middle-eastern-stone-age-tools/
