Define horizontal gene transfer. What problems does it cause for evolutionary biologists?
In the evolution of a new variant, explain the roles of genomic cytoplasmic gene factors, ecological variation, geographical isolation, climate change, hybridization and polypliodization.
What is horizontal gene transfer and how can this process potentially change how we view relatedness among the three Domains? Provide an example of a species with characteristics that results from horizontal gene transfer.
