40 Million Year Old Primate Fossils Found In Asia 91

sosaited writes "It has been widely believed that our ancestors originated out of Africa, but a paper published in Nature by Carnegie Museum of Natural History scientists puts this in doubt. The paper is based on the fossils of four primate species found in Asia which are 40 million years old, during which period Africa was thought to not have these species. The diversity and timing of the new anthropoids raises two scenarios. Anthropoids might simply have emerged in Africa much earlier than thought, and gone undiscovered by modern paleontologists. Or they could have crossed over from Asia, where evidence suggests that anthropoids lived 55 million years ago, flourishing and diversifying in the wide-open ecological niches of an anthropoid-free Africa."

My views: A page fault's expense seems to vary quite a bit among architectures/processor and also the entire system setup and assumptions on VM system. x86 architectures aren't too good at it and Linux is quite x86 minded. Sure, there aren't many other relevant architectures these days. Also, these days, VM systems aren't used today as they were back when they have been designed. Back in 1988 or 1990 (or before), a typical Unix/BSD system would often page all the time - RAM was never enough - and page in small memory portions. Today, RAM is also not always sufficient, but if not - usually one or some large process(es) gets paged out - usually doing something related with media files or other interactive stuff. For me, COW was a quite efficient overall aproach. Maybe there are some more efficient but less general aproaches around, and maybe a general purpose VM strategy would be different if designed today having all the current hardware setups in mind (and not 20 years ago). This doesn't make someone else an idiot. h.
