Killer dino 'turned vegetarian'
The "mass graveyard" of a bird-like dinosaur has been uncovered in Utah, US, Nature magazine reports this week. Scientists believe the previously unknown species was in the process of converting to vegetarianism from a rather more bloodthirsty diet.
This is very sloppy wording. There is no pre-destined path to evolution; Natural Selection works on individuals, not lineages. It is wrong, therefore, to say that the species was "in the process of converting to vegetarianism from a rather more bloodthirsty diet". What they should have said is that it had a mixed diet (and was adapted accordingly).
Still, it's a fascinating find.
