"Human Variation"

xkcd: Dilution

Tags: ,

Roughly 8 percent of your DNA isn’t really human. (How’s that for a morning wake-up call?) Instead, it’s the de-activated remnants of ancient retroviruses. All viruses hijack host cell machinery to replicate themselves, but retroviruses are a little more invasive than most. These viruses trick cells into turning viral RNA into DNA—the reverse of the normal DNA to RNA transcription process—and then snuggle that DNA right into the rest of the host’s genome. They mutate frequently and, sometimes, accidentally deactivate themselves—in which case the “dead” viral DNA just ends up hanging out in the human genome.

Resurrecting ancient viruses – Boing Boing

Science is fucking cool. Keep your jebus and your arks and unicorns, reality is pretty damned interesting.

Oooooohh, SUCK IT, creationists!

Scientists are about to create life from non-living matter. How can anybody still believe in creationism?

“We’ve made more progress on how the membrane of a protocell could grow and divide,” Szostak said in a phone interview. “What we can do now is copy a limited set of simple [genetic] sequences, but we need to be able to copy arbitrary sequences so that sequences could evolve that do something useful.”

By doing “something useful” for the cell, these genes would launch the new form of life down the Darwinian evolutionary path similar to the one that our oldest living ancestors must have traveled. Though where selective pressure will lead the new form of life is impossible to know.

Forgive me (or don’t – fuck you) for sounding like a sore winner here, and I’m obviously being a bit premature, but the fact is the abiogenesis of life has been a feather in the cap of the ignorant for too long. It’s nice to see that the rationalists may soon be plucking that one for themselves.

And Fuck You Very Much, Louisianna

Do you fuckers want to know why the civilized world makes fun of the South? Well here ya’ll go!

The text of the LSEA suggests that it’s intended to foster critical thinking, calling on the state Board of Education to “assist teachers, principals, and other school administrators to create and foster an environment within public elementary and secondary schools that promotes critical thinking skills, logical analysis, and open and objective discussion of scientific theories.” Unfortunately, it’s remarkably selective in its suggestion of topics that need critical thinking, as it cites scientific subjects “including, but not limited to, evolution, the origins of life, global warming, and human cloning.”

There is no debate within the scientific community, nor any other realm in which relatives refrain from procreation with one another, on any of these topics.

We should have let the South secede back in 1860.*

Real Time Evolution?

This could help evolution drop its “theory” status and move on up to a law.  Scientists have observed the development of a new trait after approximately 44,000 generations of e. coli in the lab.  Twelve populations, but only one of them exibited the ability to metabolise citrate, a compound in their nutrient solution.  A compound that e. coli normally cannot use.  Maybe the imaginary man did it.
