Molecular 'Culprit' in Rise of Planetary Oxygen

Cool points include searching a database of small (single fold) proteins to find old axygen producing enzymes.

Extra cool features:
Enzyme works with single metal atom to function. (Maganese)

These small proteins that use single metal atoms (like zinc fingers) are to my mind a key piece of evidence of the way out of the RNA World into our current pattern of nucleic acid polymer for memory and amino acid polymer for enzymatic action. So many small proteins working as recognition motifs - connecting RNA and a protein, and themselves binding directly to the RNA. Small proteins templating on the nucleic acid sequence, it is one direct templating step from there to the modern genetic system.

I have used this in my paper debunking "Dissecting Darwin."

From Sean Carroll's Cosmic Variance  blog:

Toward a general theory of evolution: Extending Darwinian theory to inanimate matter  
Quote
Addy Pross

Though Darwinian theory dramatically revolutionized biological understanding, its strictly biological focus has resulted in a widening conceptual gulf between the biological and physical sciences. In this paper we strive to extend and reformulate Darwinian theory in physicochemical terms so it can accommodate both animate and inanimate systems, thereby helping to bridge this scientific divide. The extended formulation is based on the recently proposed concept of dynamic kinetic stability and data from the newly emerging area of systems chemistry. The analysis leads us to conclude that abiogenesis and evolution, rather than manifesting two discrete stages in the emergence of complex life, actually constitute one single physicochemical process. Based on that proposed unification, the extended theory offers some additional insights into life’s unique characteristics, as well as added means for addressing the three central questions of biology: what is life, how did it emerge, and how would one make it?

Quoting Sean:  
Quote
It’s a paper by a chemist, published in the Journal of Systems Chemistry, but doesn’t seem to require much in the way of specialized knowledge in order to read it, have a look. The central idea seems to be something called “dynamic kinetic stability.” A stable system is one that doesn’t change over time; a dynamic-kinetically stable system is one that doesn’t change in some particular features, but only by taking advantage of some other kind of change. The water in a river flows, but what we think of as “the river” remains fairly stable over time; an organism metabolizes, but maintains its structure for an extended period; individuals within a population come and go, while the population itself can be stable.


ETA: Also check the "comments" section, where Larry Moran and John Wilkins weigh in.

Added bonus: a dynamic hypothesis for the cause of speciation. Not new, but kind of cool to see it embedded in discussion of chemistry.

32,000-Year-Old Plant Reborn From Ancient Fruit Found in Siberian Ice
By Sarah Frier - Feb 20, 2012 1:00 PM MT

Researchers in Russia have revived a fertile plant from the remains of 32,000-year-old fruit that was found buried within the fossilized burrows of ancient squirrels deep in the Siberian ice.

I especially like the implication that the various splits of the hominid line interbred for a long time before a finally completely splitting.

Yeah, between the Patterson et al paper published a few years ago, the Denisova/Neanderthal/Human paper and this paper the evidence seems to be heading that direction.

I don't see the data as consistent with there being clean splits and a large effective population size after the split
from gorilla and before that between chimpanzee and human.  This doesn't mean that there was no later interbreeding, it is just not necessary to infer that.

Woke up a bit early this morning after falling asleep with the TV on. (SCI channel of course.) I was greeted by the beginning an hour of: "What Darwin Didn't Know", then followed by two hours of "Galapagos: Beyond Darwin." I can watch stuff like this for hours... and, in fact, I have. The Galapagos segments seem to be the best but that may be because the coffee had time to kick in. A good discussion of the human impact/ecological problems of the place.

Any relatedness, whatever? (My layman's guess: Yes.)

Must be exciting days for those lucky(?) guys in their labs.

if i understand correctly, they can't tell the difference between those two possible signals (incomplete lineage sorting and postspeciation contact)

In 2010, a federal judge ruled that genes cannot be patented. U.S. District Judge Robert Sweet said he invalidated the patents because DNA's existence in an isolated form does not alter the fundamental quality of DNA as it exists in the body nor the information it encodes.

But last year, a divided panel of the federal appeals court in Washington that handles patent cases reversed Sweet's ruling. The appeals court said genes can be patented because the isolated DNA has a "markedly different chemical structure" from DNA within the body.

The Supreme Court threw out that decision, and sent the case back to the lower courts for rehearing. The high court said it sent the case back for rehearing because of its decision in another case last week saying that the laws of nature are unpatentable.

This is cool! Unfortunately, I don't have access to Nature. At any rate, this is the interesting bit:

Quote
The partial foot is the first evidence for the presence of at least two pre-human species with different modes of locomotion contemporaneously living in eastern Africa around 3.4 million years ago. While the big toe of the foot in Lucy’s species was aligned with the other four toes for human-like bipedal walking, the Burtele foot has an opposable big toe like the earlier Ardi.
