1.) Consider the impact of global warming and other anthropogenic agents on the future diversity of life on Earth. How can the fossil record help us to predict the consequences of future climate change?

2.) What controlled the timing of the diversification of life on land? Why were some phyla more successful in this new setting than others?

3.) Jumping genes (transposons) seem to produce lots of extragenetic material. What is the significance of all of this extraneous inheritance in terms of evolution?

4.) Produce a source from the peer-reviewed literature that demonstrates codon usage bias. Be sure to authenticate your source–is it really peer-reviewed? Is it published by a reputable agency?
