The message from the study, appearing online ahead of publication in Ecology Letters, says lead author Hélène Morlon, is that evolutionary diversity -- the millions of years of evolutionary innovations contained in present-day species -- is more sensitive to extinctions or loss of habitat than long thought. And that, she adds, means conservation efforts really need to take into consideration how species are evolutionarily related.
