Anyone who has been the Netherlands, especially those of us who are average UK height, will have noticed just how tall the Dutch are! Well it is well known across much of the western world that people are getting taller. I am 10 cm taller than my mum and she is 10 cm taller than her mum. This increase in height with younger generations has been tied to improving environmental conditions (more nutrition). Well a new study now suggests that natural selection may also be a contributing factor: taller Dutch women have a higher infant survival rate.
