Ya think this could be the true moment of life?
Gastrulation: the moment when the hollow ball of cells called the blastocyst form their first recognizable, functional feature. I did not realize that something so important was created in us deuterosomes at such an early stage. Two opposing points on the surface of the ball indent toward the center, eventually forming a hole. This hole in the blastocyst (called a blastopore) becomes the anus. See? Choobus has been right all along. (Back to reading Dawkins) |
So, then.... we ARE all assholes!

That's the lead-in for the current scientific explanation for homosexuality, especially in those males who have an obvious physical femininity. The genome isn't a blueprint, it's a recipe. If the subsequent expressions of genes that give the brain and body "maleness" are inhibited, then... well... John Basedow. |
Tenspace, if you're still reading 'An Ancestor's Tale,' have you come to that common ancestor of ours (I believe it was a shrew-like creature) whose poopshoot and Cave o' Creation was one in the same? It occurred to me that therein lies *some people's* preoccupation with anal -- it has an evolutionary antecedent.
[Not for the first time, I thought 'An Anecestor's Tail' might have been the more apropos title.] |

I am thankful to find that the molecular divide between crab and spider is long and deep. I wasn't about to give up tasty crab legs in a nod to my arachnophobia. |

I stopped getting non-fiction books at the library because I ended up with an empty reference shelf. Now, I'm buy all the science books so I have something to refute Salty with. :) |
