Male mammoths more often fell into 'natural traps' and died, DNA evidence suggests, Cell Press. November 2, 2017 https://www.sciencedaily.com/releases/2017/11/171102124901.htm Patrícia Penerová, David Díez-del-Molino, Nicolas Dussex, Tatiana Feuerborn, Johanna von Seth, Johannes van der Plicht, Pavel Nikolskiy, Alexei Tikhonov, and Sergey Vartanyan, 2017, Genome-Based Sexing Provides Clues about Behavior and Social Structure in the Woolly Mammoth. Current Biology. Available online 2 November 2017, In Press, Corrected Proof http://www.sciencedirect.com/science/article/pii/S0960982217312642 Although this is an interesting study, I am disappointed that they did not limit their samples to bones with well defined ages and provenance, which would have made interpreting the results less ambiguous.

Here's the latest on molecular biology / biotechnology advances and our furry friend, the Woolly Mammoth. Unlike most dinosaur fossils, Woolly Mammoth remains are often found in frozen, less-deteriorated states in Siberia; and often contain viable proteins such as collagen, from which genetic sequences can be produced.
