  • Humans Caused Extinction of Australia’s Prehistoric Giant Animals

    Ut is becoming more apparent that humans are more responsible for the extinction of the large mammals.

    Source: http://www.sci-news.com/paleontology/humans-extinction-megafauna-04554.html



    “The Australian collection of megafauna some 50,000 years ago included 1,000-pound kangaroos, 2-ton wombats, 25-foot-long lizards, 400-pound flightless birds, 300-pound marsupial lions and Volkswagen-sized tortoises,” said University of Colorado Boulder Professor Gifford Miller, lead co-author on the study.

    “More than 85% of Australia’s mammals, birds and reptiles weighing over 100 pounds went extinct shortly after the arrival of the first humans.”

    “Whether humans were responsible for the demise of the Pleistocene megafauna across Australia has been debated for many years,” said lead co-author Dr. Sander van der Kaars, a researcher at Monash University, Australia.

    “Our study found that the demise of the megafauna in southwest Australia took place from 45,000 to 43,100 years ago and was not linked to major changes in climate, vegetation or biomass burning but is consistent with extinction being driven by ‘imperceptible overkill’ by humans.”

    The researchers analyzed a continuous and precisely dated sediment core collected offshore southwest Australia that captures the last 150,000 years in high resolution.

    Environmental proxies preserved in the sediments track environmental change and the abundance of megafauna.

      Perhaps Shuny would prefer that the 'Prehistoric Giant Animals' had caused the extinction of humans.
      The first to state his case seems right until another comes and cross-examines him.

        Most evolutionists probably prefer that. Animals are always more valuable than humans, don'tcha know?

        But, survival of the fittest!

          Evolution, yes. Value judgements about the functioning of nature are irrelevant.

            As silly as saying that Christians prefer it because we believe all humans are sinners.

            And survival of the fittest deals with who leaves the most offspring

              50,000 years ago - carbon dated?

              If so, this would be remains from the Flood of Noah.

                Not likely. The dating is likely by K-Ar for the bones, and dating strata where the bones were found, comparing this with dating the related coastal strata.

                If so, this would be remains from the Flood of Noah.
                No objective physical evidence for the flood. The strata in the sediment cores is too uniform and fine textured to caused by a flood. Some of the layers are layers of fine textured loess (wind blown silt). Many fine textured deposits are varved clay deposits of ancient lakes with seasonal annual deposits we can observe forming today.

                    OK, and where do you get it from that the fine texture of loess cannot have been there during Flood?

                      I checked:

                      The scientists used radiocarbon and uranium thorium techniques to date the bone as about 50,000 years old, coinciding with the arrival of Australia’s first human inhabitants.

                      “The new monitor fossil is, minimally, 30,000 years younger than the previous youngest reliably dated record for giant lizards in Australia and for the first time, demonstrates that on a continental scale, humans and giant lizards overlapped in time,” they said.
                      http://www.sci-news.com/paleontology...rds-03267.html

                      Now, 20,000 to 50,000 carbon years (and with or without U-Pb/Th-Pb carbon seems to be 50,000) is the carbon range for Flood, according to creationists.

                      Other check:

                      The two specimens, Simosthenurus occidentalis and Protemnodon anak, have been radiocarbon dated to approximately 45,000 years ago.

                        You know I'm being facetious, right?

                        And, frankly, who cares that there are no longer 1000 pound roos bouncing about? Are we really supposed to feel ashamed for something that supposedly happened 50,000 years ago?

                              I don't feel ashamed, just disappointed i'll never get to see them.

                              I'm more disappointed about the moas, though - just a few hundred years off.
