Sure, it's interesting that American ancestors included native Australians. The summary indicates a desire for more funding to be allocated to such research. I'm failing to understand why this work is worth funding and how it affects us today. We face a lot of dire problems including food and water shortages, climate change, antibiotic-resistant bacteria, and deadly viruses like Ebola. Even projects like exploring space result in new technology being developed that eventually makes its way into our lives. I just don't see any of those benefits from throwing more funding at researching our ancestry. Why should this work be funded? Most proposals to government agencies don't get funded because the money is just so scarce. Why should something like this be funded, quite possibly at the expense of other research?
