Lizards vs Hurricanes ZdS#23

Series : Zeste de science

  • Description
 
  00:04:49  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 23: A team of researchers compared the physical features of a population of Caribbean lizards before and after the passage of Hurricanes Irma and Maria in 2017. They found that hurricanes have a part in the natural selection of that species: only individuals with larger toepads and shorter hind legs survived. An experiment with a leaf blower helped them understand why those lizards survived and not the others.
