When evaluating population drift/evolution one must keep in mind a pattern/process distinction.
- To be explained: A pattern of a sequence of ancestors to present (a phylogenetic sequence)
- Explanation: High random mutation rates + high selection coefficients –> Incremental genetic change over time (“evolution”)
We now know that the majority of anatomical changes unique to fully aquatic cetaceans (Pelagiceti) appeared during just a few million years.

The argument from junk DNA suggests that a designer would be maximally efficient in his use of information. There appears to be some information that does not execute or have any meaningful coding. Darwinism takes this issue and uses it as the result of the prediction that there would be left over information not being used due to natural selection and random mutation. However, it doesn’t appear that all junk DNA is actually junk.

The following objection to intelligent design is from observing the natural data and claiming that it could not have been designed because there are some things that lack proper function or there could have been a better way for a certain [i.e. organ] to function. This objection is often made by many theistic evolutionists, though, still non-theists object as well, is based on an inappropriate and misconceived understanding of design. The design hypothesis merely states that there is intelligent causation that permits the existence of life (a probability factor). Optimality of what has been designed is not a criterion for design. Motor vehicles break down and computers crash. With comparing motor vehicles to design, there is a natural decay and effects of heat, friction, and weather decay. What is interesting about the comparison to malfunctioning software is that a frequently known cause of malfunction is an intentionally designed malware or virus, which has been designed for the primary purpose of malfunction, it is designed to break down or decompose a previous design.

The following is the abstract from a recent paper (“Life Before Earth,” 28 March 2013) published in arXiv by Alexei A. Sharov, Ph.D. (Staff Scientist, Laboratory of Genetics) and Richard Gordon, Ph.D. (Theoretical Biologist, Embryogenesis Center). What’s quite startling and significant about this paper is that it compares to the complexity found in biology and compares it to Moore’s Law, which is a computer/computational complexity. What’s important is not the mere issue of complexity but the specific coding elements required for specific function in conjunction with complexity. Thus, the information content is very complex, robust, and specified.
An extrapolation of the genetic complexity of organisms to earlier times suggests that life began before the Earth was formed. Life may have started from systems with single heritable elements that are functionally equivalent to a nucleotide. The genetic complexity, roughly measured by the number of non-redundant functional nucleotides, is expected to have grown exponentially due to several positive feedback factors: (1) gene cooperation, (2) duplication of genes with their subsequent specialization (e.g., via expanding differentiation trees in multicellular organisms), and (3) emergence of novel functional niches associated with existing genes. Linear regression of genetic complexity (on a log scale) extrapolated back to just one base pair suggests the time of the origin of life = 9.7 ± 2.5 billion years ago.

I attended the Discovery Institute’s Summer Seminar on Intelligent Design (Social Science) in 2010. My thoughts and comments will be general since we were asked not release specifics concerning information being shared (some of it was yet-to-be published and I don’t know if it has been published yet so I’ll remain silent) and I do not want to “out” any other attendees in their academic endeavors. Once you’re labeled as an ID proponent your academic career is potentially slowed down or halted. I’ve already outed myself and I’m pretty vocal about my advocacy of design (I’m a philosopher so it’s not as academically persecuted).
I have no negative comments concerning the DI’s seminar. In fact, I have more respect for the institute and fellows. There were two concurrent seminars (natural and social sciences) that interacted with each other on a regular basis and combined on many occasions. I participated in the social science seminar and being philosophy graduate student I’m not as adept in biology, chemistry, and physics as many others are. I certainly received a welcoming abundance of science in presentations, which I thoroughly enjoyed. Some of the lecturers included Stephen Meyer, Michael Behe, William Dembski, Doug Axe, Jay Richards, Jonathan Wells, Richard Sternberg, Ann Gauger, Bruce Gordon, Jonathan Witt, John West, and Casey Luskin.

Reblogged from Jonathan M. at Evolution News and Views…
I’ve been reading the recently published book Microbes and Evolution: The World that Darwin Never Saw, which combines my two primary areas of interest: microbiology and evolution. Chapter 38 of the book is written by Kelly Hughes and David Blair of the University of Utah, two of the world’s leading experts on bacterial flagellar assembly. Having followed the work of Kelly Hughes and his colleagues for a few years, I hold their work in the highest regard. I myself have a deep fascination with the subject of bacterial gene expression. I was intrigued, therefore, when I discovered the title of Hughes and Blair’s chapter: “Irreducible Complexity? Not!”
Following a very basic overview of flagellar structure and function (also described in my own detailed review of the subject), Hughes and Blair ask, “Is the flagellum irreducibly complex, or just complex?” They write,
It is clear that the flagellum is a complex structure and that its assembly and operation depend upon many interdependent components and processes. This complexity has been suggested to pose problems for the theory of evolution; specifically, it has been suggested that the ancestral flagellum could not have provided a significant advantage unless all of the parts were generated simultaneously. Hence, the flagellum has been described as “irreducibly complex,” implying that it is impossible or at least very difficult to envision a much simpler, but still useful, ancestral form that would have been the raw material for evolution.

Reblogged from Clara Moskowitz.
The findings are detailed in a paper to appear online in [the Feb. 28] issue of Astrophysical Journal Letters…
Astronomers have captured what may be the first-ever direct photograph of an alien planet in the process of forming around a nearby star.
The picture, which captured a giant alien planet as it is coming together, was snapped by the European Southern Observatory’s Very Large Telescope in Chile. It shows a faint blob embedded in a thick disk of gas and dust around the young star HD 100546. The object appears to be a baby gas giant planet, similar to Jupiter, forming from the disk’s material, scientists say.
“So far, planet formation has mostly been a topic tackled by computer simulations,” astronomer Sascha Quanz of ETH Zurich in Switzerland, leader of the research team, said in a statement. “If our discovery is indeed a forming planet, then for the first time scientists will be able to study the planet formation process and the interaction of a forming planet and its natal environment empirically at a very early stage.”
The star HD 100546, which lies 335 light-years from Earth, was already thought to host another giant planet that orbits it about six times farther out than the Earth is from the sun. The new potential planet lies even farther, about 10 times the distance of its sibling, at roughly 70 times the stretch between the Earth and sun. [Giant Planet In the Making Spotted? (Video)]
