Mammuthus (Mammalia, Proboscidea) at the crossroads in Beringia, with a digression on mammals.

The latest DNA analyses of woolly mammoths confirm the antiquity of the differentiation of the species Mammuthus primigenius, c. 600 000-800 000 years ago. They renew also the study of the “transition” between Mammuthus trogontherii and Mammuthus primigenius. The different ways of practicing multiple approaches in evolutionary biology are evoked, with the examples of the woolly mammoth and of the interrelationships of Mammalia.
