In Etiopia, in aceiasi regiune unde a fost gasit scheletul lui Lucy s-a descoperit o sora a ei mai mica (australopitecus afarensis) in varsta de 3 ani, un schelet aproape complet, inclusiv osul hyoid a carui forma asemanatoare maimutelor sugereaza ca aceasta specie inca nu avea vorbirea dezvoltata, forma picioarelor si a bazinului indica mersul biped, acum 3.3 milioane de ani in aceasta zona exista o flora mixta, padure si savana, populatia respectiva dormind in copaci si umbland pe sol. Se presupune ca in urma unei viituri corpul copilei a fost inglobat in aluviuni si astfel a ramas intreg, nedezmembrat de pradatori. Urmeaza ca importante parti din schelet inca aflate in roca sa fie eliberate si studiate.

Aceasi stire mi-a atras si mie atentia si a fost postata ceva mai devreme pe Cronica timpului - Primii oameni. Oricum, nu strica sa avem un subiect dedicat antropologiei/paleoantropologiei.

mothman: Ar fi trebuit sa caut inainte de a deschide un nou topic, dar chiar la tine m-am gandit aseara stiind ca esti pasionat de domeniul asta. -------------------- pantha rhei

De asemenea, offtopic :
Lasa ca e bine ca te-ai gandit sa faci un subiect dedicat stirilor in domeniu si nu numai. Aici am sa mai postez si eu stiri mai interesante. Cat despre pasiunea mea pentru acest domeniu, ce sa zic...ce poate fimai palpitant decat deslusirea misterului evolutiei omului ? -------------------- The decision to build artilects or not, will be the toughest decision that humanity will ever have to make.

Asa e mothman, poate mai vin si altii si punem de-o dezbatere...

Evolution, Immigration and Trade By Paul H. Rubin Special to washingtonpost.com's Think Tank Town Monday, May 7, 2007; 12:00 AM It was once thought that humans are born as "blank slates" to be programmed by our families, culture and society. While those forces play an important role, evolutionary psychology teaches us that human behavior is also the product of the environment in which humanity evolved -- that many of our intuitions are ingrained because they contributed to our primitive ancestors' survival. Public policy pays surprisingly little attention to evolutionary psychology. Yet there are many human intuitions and behaviors that influence contemporary policy issues -- sometimes in ways that are no longer useful or perhaps even harmful to humans flourishing. These intuitions are sometimes referred to as "folk economics," and one area in which they often emerge is the international economy. Our primitive ancestors lived in a world that was essentially static; there was little societal or technological change from one generation to the next. This meant that our ancestors lived in a world that was zero sum -- if a particular gain happened to one group of humans, it came at the expense of another. This is the world our minds evolved to understand. To this day, we often see the gain of some people and assume it has come at the expense of others. Economists have argued for more than two centuries that voluntary trade, whether domestic or international, is positive sum: it benefits both parties, or else the exchange wouldn't occur. Economists have also long argued that the economics of immigration -- immigrants coming here to exchange their labor for money that they then exchange for the products of other people's labor -- is positive sum. Yet our evolutionary intuition is that, because foreign workers gain from trade and immigrant workers gain from joining the U.S. economy, native-born workers must lose. This zero-sum thinking leads us to see trade and immigration as conflict ("trade wars," "immigrant invaders") when trade and immigration actually produce cooperation and mutual benefit, the exact opposite of conflict. Conflict was common in the environment in which humans evolved. As primates, which are a very social order, our ancestors lived in relatively small groups in which everyone knew everyone else. Our minds are adapted to deal with populations of that size. Our ancestors made strong distinctions between members of the in-group and outsiders, and we still make such distinctions today -- social psychologists can create in-group and out-group feelings based on virtually any arbitrary difference between populations. The in-group and out-group intuitions help fuel opposition to expanded trade and immigration. The public intuitively believes that the beneficiaries of such policies will be foreigners, and it is easy to arouse suspicion about those who are not part of our in-group. When coupled with zero-sum thinking, this is a powerful political tool. For instance, a domestic industry or collection of domestic workers, when having difficulty competing with foreign or immigrant competitors, can use innate dislike of outsiders when advocating for increased barriers. As the evolutionary inheritors of small-group societies, our minds sometimes have difficulty appreciating risks, harms and benefits experienced by a large population. In a group of 100 people, when we observe something that has happened to someone, it is a reasonably likely event. In a society of 300 million, when we learn about something happening to one person, it may be an extremely unlikely event, but we often perceive it as likely when we see it on the news. This instinct also shapes our perspective on trade and immigration. We understandably have great sympathy for workers who lose their jobs because they can't compete with foreign workers, but we have difficulty appreciating the benefit that our nation of consumers gains from the products of foreign laborers. As products of evolution, humans cannot help but be born with certain biases. But we are not condemned to this evolutionary programming; we can identify the biases and recognize when they lead us astray in the modern world. American history is marked by many periods of openness to trade and immigration, and those periods have often featured strong economic growth and human prosperity. However, American history has also seen many instances in which our zero-sum and anti-outsider intuitions reemerged, whether in the form of prohibitions against "dogs or Irishmen" or policies against "outsourcing." A useful analogy is between speech and reading. All humans growing up in a normal environment learn to speak, but reading must be taught because it does not come naturally. Folk economic beliefs are like speech -- we get them without trying. A deeper understanding of economics is like reading -- it must be taught. America's success in lowering its barriers to outsiders shows that we can and do learn. But like reading, we must teach each generation anew. Paul H. Rubin is the Samuel Candler Dobbs Professor of Economics and Law at Emory University and the author of Darwinian Politics: The Evolutionary Origin of Freedom (Rutgers University Press, 2002). He has been writing a series on evolution and economic behavior for the Cato Institute's journal Regulation. View all comments that have been posted about this article. sursa -------------------- |

Barbatii europeni sunt rude cu faraonul Tutankhamon, de ce doar barbatii? femeile ale cui rude sunt? Incet dar sigur ne apropiem de existenta unui stramos comun al europenilor care conform unei ipoteze a emigrat din Caucaz spre Mesopotamia, Egipt in sud si spre vestul Europei in nord. As fi curios sa aflam daca osemintele descoperite in sudul Romaniei fac parte din acelasi grup, s-ar lega de o alta ipoteze conform careia in piramidele egiptene s-a gasit aur provenit din muntii Apuseni

Recent a aparut o noua teorie pe baza scheletelor preistorice descoperite in Georgia (Caucaz) ... si se pare ca NU au existat specii umane ci o singura specie umana cu un grad mare de variabilitate de la H. Ergaster pana la Omul Modern, adica ceva similar variabilitatii soiurilor de caini ( v. ogarul englezesc vs. Pug):
