Monday Science Links

This weeks links to Science! (science science science...):

• Greg Laden from Greg Laden's Blog gives us a good lesson on The Three Necessary and Sufficient Conditions of Natural Selection (When you are done reading this post you should be able to: Make erudite and opaque comments to creationists that will get you points with your web friends. Write really tricky Multiple Choice Exam Questions if you are a teacher. Evolve more efficiently towards your ultimate goal because you will be more in control of the Random Evolutionary Process (only kidding on this third one...))


• Brian at Clastic Detritus shows us some cool photos of trace fossils - Rocks and Life. (Trace fossils are not body fossils; they are simply tracks and traces of organisms preserved in the rock record.)
  


• John at John Hawks Anthropology Weblog interviews Mica Glantz, who's in Kazakhstan "working on a reanalysis of Teshik-Tash [who] more closely resembles Upper Paleolithic modern humans from Central Europe than European Neandertals." Fascinating stuff.
  


• Prometheus at A Photon in the Darkness talks about "mild" hyperbaric oxygen therapy for autism and whether it works, and why.


• Chris at Highly Allocthonous talks about how the air we breathe became, well, breathable.


• And because it's Thanksgiving, a bonus: Brian at Laelaps on sexual dimorphism and why some have it and some don't - strategies for reproduction.

Enjoy!
