The presence of oxygen in the Earth’s atmosphere is a critical component to life as we know it. But how did our atmosphere come into existence? What events created the oxygen rich air that we breathe? Scientists think that the answer lies in the lowliest of creatures; creatures that we don’t even notice unless we pull back the muck and ‘dig deep’.
The Netherlands is officially the tallest country on planet Earth. For the most part, scientists believed this was due to wealth, a rich diet and quality health care. But a new study suggests that the overall height of Dutch people may actually be human evolution in action.
Scientists have identified 180 genes that influence your height. Individually, all account for a very small effect, but combined, may explain up to 80% of the variation in height of a population.
