Language doesn't precisely reflect reality when describing change. Is birth a process or a result? How about reproduction in general?

What is the *result* of speciation? Absolute reproductive isolation? Probabilistic reproductive isolation?

That is an interesting way of arriving at an answer to the original question.

If speciation is the process, isolation is the result.

If X is the process, speciation is the result.

I have trouble filling in X, so I prefer the first version!

OK, but couldn't it just as easily be

Isolation is the process and speciation is the result?

Where isolation equals physical, anatomical, behavioral, etc?

How about incremental change is the process; isolation is the result; speciation is the applied term?

How about look at the definition of "speciation", and see if it describes the process or the result.

Of course, if there are multiple definitions of "speciation", both answers might be produced depending on which definition is selected.

(Whether that selection is natural or artificial doesn't matter here.)

Well, in a scientific sense, speciation is divided into 'types' (like sympatric speciation and allopatric speciation) by the process that results in the speciation.

That's why my thought was the 'speciation' by itself should be a result instead of a process.

13% of H.S. Biology Teachers Advocate Creationism in Class
 
Quote
The majority of high-school biology teachers don't take a solid stance on evolution with their students, mostly to avoid conflicts, and fewer than 30 percent of teachers take an adamant pro-evolutionary stance on the topic, a new study finds. Also, 13 percent of these teachers advocate creationism in their classrooms.

This is sad.  Not unexpected, but sad nonetheless

Last week in Science is a sweet phylogeny that suggests CTVT mitochondrial capture events have happened multiple times, even in house dogs, wolves and coyotes.  What a freak show

This is really cool! A novel resource–service mutualism between bats and pitcher plants. Here is the abstract:

Quote
Mutualistic relationships between vertebrates and plants apart from the pollen and seed-dispersal syndromes are rare. At first view, carnivorous pitcher plants of the genus Nepenthes seem to be highly unlikely candidates for mutualistic interactions with animals, as they form dimorphic terrestrial and aerial pitchers that trap arthropods and small vertebrates. Surprisingly, however, the aerial pitchers of Nepenthes rafflesiana variety elongata are poor insect traps, with low amounts of insect-attractive volatile compounds and low amounts of digestive fluid. Here, we show that N. rafflesiana elongata gains an estimated 33.8 per cent of the total foliar nitrogen from the faeces of Hardwicke's woolly bats (Kerivoula hardwickii hardwickii) that exclusively roost in its aerial pitchers. This is the first case in which the faeces-trapping syndrome has been documented in a pitcher plant that attracts bats and only the second case of a mutualistic association between a carnivorous plant and a mammal to date.

I always thought the "pitchers" looked like elongated chamberpots.  Apparently the bats do as well.

You're correct. I live across the street from my uni in Wilmington, NC, so it's a bit attenuated here, but my son still lives in Jacksonville, home to the largest Marine Corps base in the world and lots and lots of seriously deranged Christians.

Let's talk planets!!

http://www.nasa.gov/mission_pages/kepler/news/kepler_data_release.html

5 near Earth-like planets in their habzones! Extrapolating from our own solar system, at least one of those should be closer to an Earth than a Venus or Mars.

Can someone tell me which way Kepler is pointed? Is it looking inwards toward the galactic center, or along a tangent to Sol's radius from the galactic center?

The mean velocity of -57.16 kms-1 is measured relative to the Solar System barycenter; compared to the local velocity dispersion of ~30 kms-1, this Galactic velocity suggests that Kepler-11 is a member of the thick disk of the Milky Way.

Here's a non-paywalled .pdf of Supplementary Data on the Kepler-11 system that might help.

If you liked the Cold Spring Harbor subject collection on the origins of life, this collection on RNA World topics will also make you happy.

For the KrisBob trolls out there, here's a quote from Steven Benner's article "Setting the Stage: The History, Chemistry, and Geobiology behind RNA"

 
Quote
No community-accepted scientific methods are available today to guide studies on what role RNA played in the origin and early evolution of life on Earth. Further, a definition-theory for life is needed to develop hypotheses relating to the “RNA First” model for the origin of life. Four approaches are currently at various stages of development of such a definition-theory to guide these studies. These are (a) paleogenetics, in which inferences about the structure of past life are drawn from the structure of present life; (b) prebiotic chemistry, in which hypotheses with experimental support are sought that get RNA from organic and inorganic species possibly present on early Earth; ( c) exploration, hoping to encounter life independent of terran life, which might contain RNA; and (d) synthetic biology, in which laboratories attempt to reproduce biological behavior with unnatural chemical systems.


Science, he's doin it rite.

Howdy people,


I ran into this: "Trisha Gura, "Bones, Molecules or Both?" and when I typed it in to get a search, holy deep quote mine batman, in addition to the site of the magazine, Nature, that published it, it seems that this is a "major find" for every ID or Creation website out there.

Even though I am not a biologist, after reading what the writer stated and then what the ID sites think she said there's is a reach. I think that the ID and YEC sites are in the words of the great philosopher Inigo Montoya

Yes, the YEC sites are grasping at straws. IMHO, Gura's article (science journalism, not peer reviewed research) exaggerated issues that existed at the time.

Gura's article was taken up almost immediately by the ID crowd. If you go a page or two down into the Google search, you'll find an NCSE site hit. The DI had referenced the Gura article in a bibliography they submitted to the Ohio State BOE, back in 2002. The NCSE site shows that Gura responded to their request for answers to a questionnaire asking if the author agrees that their article questions evolution. (Gura is not quoted by the NCSE, however.)

The ID crowd (Casey Luskin, for example) is never going to engage on the level of incongruence in phylogenies vs the overwhelming level of congruence in those same phylogenies. Its not like one method groups dogs and starfish, while the other doesn't. The incongruences are at the twig level compared to the overall tree of life. Places where the data is spotty on both the molecular and morphological sides.

And in the end, what is the scientific response to incongruences?

The problem with GM crops is not biological. If GM crops could be wrested away from the seed and chemical conglomerates (yeah, we're looking at you, Monsanto), there would be some real benefits (salt-tolerant plants, for one). Sadly, that seems very unlikely.

Clay-Armored Bubbles May Have Formed First Protocells: Minerals Could Have Played a Key Role in the Origins of Life

http://www.sciencedaily.com/releases/2011/02/110207073744.htm

We've all heard for donkey's ears about montmorillonite, a common clay, and how helpful it can be as a catalyst and tethering spot for long chain molecules. Now it appears that scientists have found a way for it to form vesicles that may help concentrate longer molecules. Short precursors enter the clay shell through pores. This happens more easily than long molecules escape, leading to a natural buildup of long biologically useful molecules.

Darwin was wrong (again) (about something he couldn't have known about) (again)!!1!

http://www.plosgenetics.org/article....1001284

The real story, of course, is that Darwin was right. Since Darwin didn't know anything about how traits were passed down, evolution is not the RM+NS creationist shorthand meme. Variation and selection, yes, but variation has many sources. HGT means that even an asexually reproducing bacteria can have two parents.

We can now make the exciting prediction that Lenski's E. coli cultures aren't going to change in any exciting ways, but if you started with a dozen species of archaea, bacteria, and virus, the results would be very different.

Paging Roger Penrose...

http://spectrum.ieee.org/biomedi....roscope

A very cool experiment in which flies are shown to differentiate between two versions of a chemical, one normal, the other where the hydrogen atoms have been swapped out for deuterium. If smell equalled the molecular shape and charge surface, they shouldn't be able to do that.

I put the shout out to Penrose up top because he has speculated that free will arises from quantum fluctuations in the human brain. This study is about a quantum phenomena in an extension of the brain. I can't wait for this to be picked up by the Spiritual Brain Drain herself.

From another site:

Quote
Binding is a function of molecular shape, polarity and the strength of interactions like hydrogen bonding. On H/D substitution neither shape nor polarity change noticeably, but the hydrogen bonds involving deuterium could indeed vary in energy from those based on normal hydrogen.
Cf. "Effect of Deuterium on the Strength of Hydrogen Bonds", by Melvin Calvin, Jan Hermans Jr., Harold A. Scheraga J. Am. Chem. Soc., 1959, 81 (19), pp 5048–5050
