The Saiga Antelope, which is currently threatened with extinction, used to be much more flexible in its habitat and food choices in the past than previously assumed, scientists have discovered. Based on carbon and nitrogen isotopes in the collagen from the antelopes’ bones, the scientists compared the diets of fossil versus modern-day Saiga. In their study, they reached the conclusion that today’s populations are not obligatorily bound to their current habitat. This insight offers new hope for this endangered species.
