Virtual Dinosaur Dig

24 Jan

The Smithsonian has a cool virtual dinosaur dig where students learn how fossils are uncovered, transported, and then assembled.  Neat stuff!

Chance, randomness, and evolution

2 Nov

Just read a really nice article over on Science Blogs entitled “Evolution: A Game of Chance?”  It helps clarify how evolution may be caused by random events (mutations in genes) while demonstrating that the processes of evolution are not random at all (selection).  There’s a nice poker analogy, too. 

Kudos to the author, Christie Wilcox.
