From the Ted Talk by Daniel Wolpert: The real reason for brains


Unscramble the Blue Letters


And so it turns out we're so stereotypical, our brains have got dideaectd neural circuitry to decode this stereotyping. So if I take some dots and set them in motion with biological motion, your brain's circuitry would uendsnatrd inntstlay what's going on. Now this is a bunch of dots moving. You will know what this person is doing, whether hppay, sad, old, young — a huge amount of information. If these dots were cars going on a racing circuit, you would have abeloulsty no idea what's going on.

So why is it that we move the particular ways we do? Well let's think about what really happens. Maybe we don't all quite move the same way. Maybe there's variation in the population. And maybe those who move better than others have got more cchnae of getting their children into the next generation. So in evolutionary slaces, movements get better. And perhaps in life, movements get better through learning.

Original Text


And so it turns out we're so stereotypical, our brains have got dedicated neural circuitry to decode this stereotyping. So if I take some dots and set them in motion with biological motion, your brain's circuitry would understand instantly what's going on. Now this is a bunch of dots moving. You will know what this person is doing, whether happy, sad, old, young — a huge amount of information. If these dots were cars going on a racing circuit, you would have absolutely no idea what's going on.

So why is it that we move the particular ways we do? Well let's think about what really happens. Maybe we don't all quite move the same way. Maybe there's variation in the population. And maybe those who move better than others have got more chance of getting their children into the next generation. So in evolutionary scales, movements get better. And perhaps in life, movements get better through learning.
