A study into the brooding behaviour of birds has revealed their dinosaur ancestors shared the load when it came to incubation of eggs.
Research into the incubation behaviour of birds suggests the type of parental care carried out by their long extinct ancestors.
The study aimed to test the hypothesis that data from extant birds could be used to predict the incubation behaviour of Theropods, the group of carnivorous dinosaurs from which birds descended.
