While I enjoy Hogan very much, I recently read the "Giants" trilogy and
was bothered by some of the biology.
  1--Why should Minervan biochemistry be compatible with Terrestrial,
  to the point of being able to eat each other's food. Are the terrestrial
  amino acids the only possible ones?

  2--The self-immunization system that is proposed as the reason only man
  developed intelligence is pure pseudoscience, unless Hogan is talking
  about autoimmunity. Also, how does he them explain large brain size and
  complexity in cetaceans and elephants?

Also, I wasn't happy with the closed temporal loop in "Giant's Star". Might
not such a loop be the temporal equivalent of a black hole?
