Doesn’t everyone like sex? Of course they do — and the designer made the sexual organs of angiosperms, namely, flowers, to be the most spectacularly beautiful structures in biology, so he evidently likes sex too.  An invited review (open access) in Genome Biology and Evolution explores the “incredible diversity of sex chromosome systems,” but especially how their evolutionary origins refuse to fit any one theory. See, “Sex chromosome evolution: So many exceptions to the rules.” From the abstract: Despite many convergent genomic patterns exhibited by independently evolved sex chromosome systems, and many case studies supporting these theoretical predictions, emerging data provide numerous interesting exceptions to these long-standing theories, and suggest that the remarkable diversity of sex chromosomes is matched by a similar diversity in their evolution.

“Oh my God! Look at that picture over there! There’s the Earth coming up! Wow, that’s pretty!” These were the words William Anders spoke to the other two Apollo 8 crew members, Jim Lovell and Frank Borman, just before he took the now famous “earthrise” picture on December 24, 1968. Since then, other Apollo astronauts and even unmanned lunar spacecraft have taken similar pictures (see above). Notice how Anders reacted to the view of Earth rising over the lunar limb; these were obviously spontaneous reactions to something that caught him off guard. He expressed surprise and noted how pretty it looked. These are expressions of beauty. A beautiful thing surprises us. The fact that the earthrise pictures have been reproduced so many times speaks to their universal appeal. Probably most…
