My next sac is on this content of the bio study design...I'm feeling really stressed out understanding the concepts. Could someone give some advice and web links to study this content. Thanks
• a qualitative treatment of changing allele frequencies in a population and the consequences:
– the concept of the gene pool
– environmental selection pressures, gene flow, genetic drift (founder and bottleneck effects)
– natural selection as a mechanism for biological evolution
• evidence for biological evolution over time:
– the geological time scale; relative and absolute dating techniques
– the fossil record; biogeography; comparative morphology; molecular homology
• determination of evolutionary relationships: comparison of DNA sequences; comparative genomics; mitochondrial DNA; phylogeny
• patterns of biological change:
– allopatric speciation
– divergent and convergent evolution
– extinctions
