New dates for earliest human occupation of Australia

Earth-Pages | 20 July, 2017
When modern humans first reached Australia has an importance beyond the starting date for the island continent's archaeology and confirmation that their ancestors are the oldest known migrants from Africa. The first native Australians carried within their genome important information about the minimum date at which some non-Africans interbred with more archaic Neanderthal and Denisovan humans, traces of whose DNA are are present in that of living Australian aborigines. Most dating of when modern humans first reached different parts of the non-African world has relied on the radiocarbon method, which is suspect from beyond 40 to 45 ka as 14C produced earlier has decayed to levels that are now below the practical limit of detection and measurement. It is therefore no accident that the bulk of 'first-arrival' dates for Eurasia and Australasia are around 45 ka. In fact, any accurate age, however old, for the earliest skeletal remains only indicates the minimum date of arrival until other remains are discovered.

The climate has always changed. What do you conclude?

RealClimate | 20 July, 2017
Probably everyone has heard this argument, presented as objection against the findings of climate scientists on global warming: "The climate has always changed!" And it is true: climate has changed even before humans began to burn fossil fuels. So what can we conclude from that?

Meanwhile, what are the Wooster Paleontologists up to?

Wooster Geologists | 19 July, 2017
Wooster, Ohio -- The igneous petrology team has a thorough and entertaining report about their activities in the Wooster geology labs this summer. It has encouraged the summer paleontologists (that would be me and Macy Conrad '18) to give a progress report. Compared to the high-temperature geochemistry going on in the basement, we are decidedly low-tech upstairs in the Paleo Lab!
