My Lab: Plant Genome Evolution and Diversity 1) What is the relative role of natural selection vs. genetic drift in governing genome evolution and structuring diversity? 2) What is the rate and genetic basis of positive and negative selection?
Background image of page 2
The Course So Far: Processes of Evolution -mutation, selection, drift, recombination and gene flow all cause evolutionary change -These processes provide basic foundation for all evolution -Evolution as changes in allele frequencies over time

Evolutionary processes and large-scale evolution •Natural selection, genetic drift, mutation, migration sources of MICROEVOLUTION, but can these processes explain taxonomic diversification (MACROEVOLUTION)? • left nagging doubts for early researchers studying evolution vs.
Background image of page 4
Nagging Doubts by Early Researchers 1) How and why do organisms diverge and diversify? 2) How can we explain patterns of variation across species? 3) Can the evolutionary processes of mutation, selection, drift explain how we got millions of diverse species on earth?
