Why Are Trees Shaped Like That?

Series : Zeste de science

  • Description
 
  00:04:10  2018  HD 16/9  Color  Sound

The Youtube channel Zeste de science explores all aspects of scientific research, proving that even the most complicated scientific facts can be explained in less than 5 minutes, and that even the most seemingly trivial events of everyday life, if thoroughly studied, can contribute to the biggest technological advances.
Episode 12: How come all trees have more or less the same shape? Through a virtual simulation of the evolution of a forest, a cross-disciplinary research group revealed that trees compete for the access to sunlight, and that the diameter of tree branches depend on the wind. These two factors, light and wind, explain the shape of trees.
