innate mathematical ability
Where does our ability to do abstract maths come from? A new study sheds some fascinating light on the question. 
You don't need to count to see that five apples are more than three oranges: you can tell just by looking. That's because you were born with a sense for number. But is that sense related to the mathematical abilities you develop later on?

Human reasoning is biased and illogical. At least that's what a huge body of psychological research seems to show. But now a psychological scientist from the University of Toulouse in France has come up with a new theory: that logical and probabilistic thinking is an intuitive part of decision making, only its conclusions often lose out to heuristic considerations. 
People as well as animals are born with a sense for numbers. But is this inborn number sense related to mathematical ability? A new study suggests that it is. 
How did we evolve our capacity for maths? Does maths piggyback on our ability for language, or is it a completely separate faculty? Is it dependent on culture? Plus spoke to the cognitive psychologist Rosemary Varley to find some answers.
