Revision as of 14:28, 13 September 2010
It basically starts from this blog post. The question is: why are Insecta the most diverse group of arthropods, if not of living beings, on Earth's land, while Arachnida and other arthropod groups aren't?
Here I collect some material for further posts on the subject.
Evolution of Arthropoda
- Marine evolution of Arachnida: "The oldest known scorpions lived around 430 million years ago in the Silurian period, on the bottom of shallow tropical seas.[15] These first scorpions had gills instead of the present forms' book lungs." ( Scorpion )
- Recent evidence for Pancrustacea hypothesis based on nuclear genes phylogenies: Regier et al. 2010
