In a new study, published in the journal Animal Behaviour, scientists from the University of Oxford discovered that when a duck gathers visual information with one eye, that short-term information is not available when the other eye controls behavior. How did they find out? By observing how newly hatched ducklings that are shown a substitute mother object with only one eye do not recognize it when they have only the other eye available.
A recent study has discovered that newborn ducklings can process abstract thoughts without the help of training from parents and other external forces. The study disproves John Locke's statement that abstract reasoning separates human beings to all other animals.
