Answer: 1. Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
2. The changes in our behavioral patterns and adaptations that are caused by these technological advances could prove to be the primary driving forces behind the next stage of evolution for our species. These members of the species are more likely to reproduce and pass their genes on to their children.

Ok, so I'm not sure if the man affected with fh has Ff alleles or FF alleles. However, I think by the question that he has Ff alleles. So there is a 50% chance that the offspring will be affected by fh.
