A Biologist's Mother's Day Song: Slightly more than half of everything I am is thanks to you

Happy Mother's Day!

Full lyrics (and guitar chords, for those of you so inclined) are below, but here are a couple of highlights: 
Just like two strands of DNA are spirally entwined
Your nature and your nurture are inspiringly combined
Scientists remind me and I find that it is true
Slightly more than half of everything I am is thanks to you
I got nutrients and transcription factors
and nearly everything that matters
plus my prenatal environment (transplacental inheritance)
mRNA, mitochondria,
That back in the day once belonged to ya...


Lyrics:

To make one me you just add
Half of mom and half of dad
That is what I once believed
But I know now that I was wrong
I got so much more from you mom
Than just half a set of genes

I got nutrients and transcription factors
and nearly everything that matters
plus my prenatal environment (transplacental inheritance)
mRNA, mitochondria,
That back in the day once belonged to ya (theyre cytoplasmic)
and I just want to thank for supplying them

Just like two strands of DNA are spirally entwined
Your nature and your nurture are inspiringly combined
Scientists remind me and I find that it is true
Slightly more than half of everything I am is thanks to you

Mitochondria power my cells
and they have DNA as well
Transcription factors modulate transcription
And since theyre in the cytoplasm
The eggs the only one that has em
and sperm I guess they dont have much ambition

My sex determination gene means that Im a guy
From you I got my X chromosome, from Dad I got my Y
X has over a thousand genes, Y has less than 92
Thats why more than half of everything I am is thanks to you

I roomed in your womb for nine whole months and never paid the rent
Your glucocorticoids shaped my hypothalmic development
I took in your blood and sucked it dry of every nutrient (its gross but true)
Sometimes I wonder where the time went (where did it go)
Sometimes I wonder where it went

I know Ill never understand all you have done for me (I'm not that smart)
But since you paid for college I'll get my B. S. degree (bachelor of science)
And I have learned its not BS but absolutely true
Slightly more than half of everything I am is thanks to you.

"It's not an even 50/50 split you get a disproportionate share of your DNA coming from your mom. Really important." - Robert Sapolsky

James Barrie was born on May 9, 1860 - here's the Dark Side of Peter Pan

Sir James Matthew Barrie, 1st Baronet, OM was a Scottish novelist and playwright, best remembered as the creator of Peter Pan. He was born on May 9, 1860, educated in Scotland, and then moved to London, where he wrote a number of successful novels and plays.

When the first baby laughed for the first time, the laugh broke into a thousand pieces and they all went skipping about, and that was the beginning of fairies.

~ James Barrie, Peter Pan

Every time a child says, "I don't believe in fairies," there is a little fairy somewhere who falls down dead.

~ Id.

Fascinating story about James Barrie, the author of Peter Pan, over at Neatorama - read the whole thing. Some excerpts:

"All of James Barrie's life led up to the creation of Peter Pan," wrote one of his biographers. 

A pivotal point came in 1866 when Barrie, the youngest in a Scottish family of ten children, was six: his brother David, the pride of the family, died in a skating accident. Barrie's mother was devastated. To comfort her, little James began imitating David's mannerisms and mimicking his speech. This bizarre charade went on for years… and only got weirder: when James reached 13, the age at which David had died, he literally stopped growing. He never stood taller than 5', and didn't shave until he was 24. He always had a thin, high-pitched voice... 



In 1899, while still unhappily married, Barrie befriended young George, John, and Peter Davies and their mother, Sylvia, in London's Kensington Park. The boys' father, Arthur Davies, was too busy tending to his struggling career as a lawyer to spend much time with the family. So childless Barrie was only too happy to play with the Davies boys. He became a frequent caller at their home, and even rented a cottage nearby when they went on vacations in Surrey. 

Barrie idolized the children's beautiful mother. But it was with the children that he could truly be himself. He met with them daily in the park or at their home. They played Indians together, or pretended to be pirates, forcing each other to "walk the plank." Barrie made up stories for the boys, featuring talking birds and fairies, and acted them out.

Barrie always acknowledged that the Davies boys' free-spirited youth was the inspiration for Peter Pan. "I made Peter by rubbing the five of you together, as savages with two sticks produce a flame," he wrote on the dedication page of the printed version of the play. More than that, however, the Davies family - loving mother, impatient father, and adorable sons - served as Barrie's model for the Darlings in the play. He even used their names:

* Mr. Darling was named after the eldest boy, George Davies.

* Jack Davies became John Darling.

* Michael and Nicholas became Michael Nicholas Darling.

* Peter Davies' name went to Peter Pan.

As for the author, he appears as Captain James Hook, whose right hand is gone. Barrie suffered paralysis of his right hand from tendonitis.

But this story has no happy ending. Arthur Davies died of cancer, which left Barrie and Sylvia free to marry. Barrie went so far as to give her an engagement ring, but then she, too, died of cancer. Suddenly Barrie was the legal guardian of five boys, ages 7 to 17. George, the eldest Davies child and Barrie's favorite, died in World War I in 1915. Michael drowned in a pool at Oxford while being taught to swim by a close friend; there were rumors of a suicide pact. John married and distanced himself from Barrie. Peter Davies committed suicide as an adult in an attempt to escape, some say, from forever being called "Peter Pan."
