Evolution? The headline seemed to be saying there was more data showing how ancient apes split into two groups, one heading toward modern gorillas and the other leading to other modern apes — and humans. I’m blogging about “Fossils Shed New Light on Human-Gorilla Split,” LiveScience.com, By Charles Q. Choi, 2/11/2016.
As usual, the title of the original research report was a bit clearer: “New geological and palaeontological age constraint for the gorilla–human lineage split.” (Nature 530, 215–218 (11 February 2016) doi:10.1038/nature16510) In other words, the data merely shows a limit on when the split might have happened — assuming that it did happen, and that the dating method is accurate.
