This is a delayed post. I’ve sequestered myself for the weekend to work on The Lilith Quotient. No internet access except to Thesaurus.com and various dictionaries online.
I’ve even allocated specific blocks of time for Playtime With Kate. I really have to conquer the procrastination and undiagnosed ADHD so I can make some progress on my book, or I’ll be a little old lady before it’s done.
With that in mind, I thought I’d find something interesting in the archives to re-post for your perusal.
Help! My Vitamin C Gene Is Broken!
Ok, sorry ’bout that post mistake. All better now.
So I’m looking into this broken Vitamin C gene because of Bourgeois Rage’s comments on The Science Thread. Yes, I’m aware I’m breaking my own rules. My Blog, My Rules, My Prerogative, Behold the Door.
This makes sense to me. It’s a very strong argument for common descent. If I understand this correctly, and thanks to Kate and BR I think I do, here’s how it goes.
Each of those children are different, and each of them is a combination of Mr. S and Mrs. S., and each of them potentially has some slight genetic mutation that neither Mr. nor Mrs. S. has.
For instance, Yorick, William, and Tara all have a mutation that gives them some better nerve connections in their brains and makes them a little smarter.
Zack, Xavier, William, Tara, and Samuel have longer legs than either of their parents, enabling them to run faster.
Yorick wound up with much shorter legs.
Rachel got different colored eyes and thicker fur, and Tara, Uhura, and Horatio got really attractive Snuffleupagus genes.
Now, because his legs were so short, Yorrick wound up getting eaten by the mean ol’ Sabretooth Tiger. He was eaten before he could have kids, and thus, that mutation will not carry on to the next generation.
William, because of his larger, better brain waxes poetic “Alas. Poor Yorrick. I knew him, Horatio.” But Horatio is kinda dumb, so he doesn’t get it.
Now, Zack, Xavier, William, Tara, and Samuel all live to make babies, because they can out run the Sabretooth Tiger.
Horatio joins Yorrick in the victims column, ’cause he didn’t run at all.
Tara and Uhura are very, very pretty, so they make lots of pretty babies. All the boy Snuffleupagi want to jump their bones. Tara has an advantage, though because her legs are longer, so all her babies survive, while some of Uhura’s babies get eaten and some don’t.
Rachel’s babies have thicker fur and pretty eyes, and she’s smart enough to at least stay in the trees if she can’t out run the Sabretooth Tigers. (I made a slight change here because it was brought to my attention that it may have undertones that I did not intend. Thank you.)
Eventually, all the babies that grow up have babies of their own, and these babies inherit the traits of their parent. Plus they inherit some of the traits of their other parent. Plus, they have mutations of their own.
Down the road, Rachel’s descendants are so different from William’s descendants that they can’t mate anymore between them.
At this point, we have two different species. The broken Vitamin C gene would be like the long legs or the different eyes. It gets passed down to some of the descendants of Mr. and Mrs. Snuffleupagus, but not all. That’s why it shows up in primates, but not other mammals.
Am I all good so far?
