Yes, the claim that stone age humans had the ability to bring about the demise of Ice Age animal life is up and running once again. At http://phys.org/print364718233.html … new data presented at the conference of the Society of Vertebrate Palaeontology in Dallas in October (2015) has provided the spark to trot out the theory once again. Apparently, the fact that early Aborigines were living in Australia prior to the extinction event between 40 and 27,000 years ago is all they needed to point the finger. The idea of Catastrophism did not enter their skulls – let alone their brains.
A much more interesting piece of research is at http://phys.org/print364730798.html … jumping genes. Scientists have discovered some unusual genetic diversity among the primates – which includes the human line. These are known as jumping genes and they have been implicated in schizophrenia amongst other things. Once the idea has seeded more research will come up trumps and find all kinds of other things have an association in jumping genes.
