No, it is simple. Data mining has nothing to do with databases because you can practice it without using a database.
>That's true (I read that data mining was designed to find patterns in data across enterprises of databases most structured some unstructured); however, you still need data.
You guys are being very superficial when you talk about data mining. You have to look at what you're actually doing, it does not matter where you get your data.
>Good point. Again you need data.
However, when you practice data mining, you could also use a database, but they are seperate. As data mining really has nothing to do with a database.
>Data mining needs data to produce information.
As for the DNA business, the genetic code at this point has no structure. So I would say you're assuming too much about the evolutionary business.
> Sure it does. That's why species replicate into species of the same species for example.
I think what you meant is that these organisms may share 50% of the same genes etc. From a molecular stand point, the creationist have already been blown out of the water. When we share 99.99% the same genes as a chimpanzee and now they are cracking down on this evolutionary business in genes.
> The "99 % genetic similarity" has been enshrined as a cultural icon and used as a "proof" evolution. Presumably, the 99 percent sequence overlap for proteins and DNA proves that humans and chimps arose from a common ancestor some time in the relatively recent past. According to this view, the small genetic differences arose after the human and chimpanzee lineages split as a consequence of mutational changes within each species' genetic material.
Studies that reveal a 99 percent genetic similarity between humans and chimpanzees have stacked the deck in a way that guarantees a high degree of likeness. Until recently, evolutionary biologists have looked for only a single type of difference between human and chimpanzee DNA sequences, namely
substitutions of one nucleotide for another. When researchers expand the comparison to include differences that involve insertions and deletions (called indels), marked dissimilarities between human and chimpanzee genomes become evident.
Another study that used this type of approach found a much more
limited genetic similarity when a 1,870,955-base-pair segment of the chimpanzee genome was compared with the corresponding human genome region. When only substitutions were considered, the sequence similarity proved about 98.6 percent. Including indels in the comparison dropped the similarity to 86.7 percent.
In the spring of 2004 the International Chimpanzee Chromosome 22 Consortium affirmed this initial observation when they generated a detailed sequence of chimpanzee chromosome 22 and compared it to human chromosome 21. They discovered a 1.44 percent sequence difference when they lined up the two chromosomes and made a base-by-base comparison.
But they also discovered 68,000 indels in the two sequences, with some indels up to 54,000 nucleotides in length. Another study achieved similar results. This work compared a 1.8-million-base-pair region of human chromosome 7 with the corresponding region in the genomes of several vertebrates. Only a third of the differences between humans and chimpanzees involved substitutions.
Indels accounted for roughly two-thirds of the sequence differences between these two primates. Of these indels, about one-half were greater than 100 base pairs long. As for mitochondrial DNA, a 91.1 percent sequence similarity was seen when the entire sequence was compared, not a 99 percent similarity. This factor promises to be significant because mitochondria play a role in energy metabolism. Several neurodegenerative and muscular degenerative diseases actually stem from mutations in mitochondrial DNA.
Honestly I could write a book on this issue but the bottom line is that although human and chimpanzee genomes display great similarity, that similarity has been magnified to some extent by research methodology. Researchers are starting to uncover significant differences. Results of large-scale comparisons must be considered preliminary, as it's not yet clear what the genetic differences mean in terms of anatomical and behavioral characteristics. However, greater clarity will likely come as research progresses. Already the newly recognized genetic differences between humans and chimpanzees complicate the picture for biologists who view the high degree of genetic similarity between humans and chimpanzees as proof of shared ancestry. If 99 percent genetic similarity represents a close evolutionary connection, what does the more recently measured 86.7 percent genetic similarity mean? And in this discussion small is significant my friend as several recent studies demonstrate that even subtle genetic differences can manifest themselves dramatically in terms of an organism's anatomy, physiology, and behavior.
Sure researchers are beginning to gain knowledge of gene expression patterns in humans and the great apes. Yet these initial studies already indicate that anatomical, physiological, and behavioral differences between humans and chimpanzees (as well as the other great apes) result much more from differences in gene expression than from DNA sequence disparities. In many instances, it's not the genes present that are important but the way they function. What does it mean to be 98 percent chimpanzee? In terms of evolution: essentially nothing.
The most comprehensive genetic comparisons indicate that humans and chimpanzees share a genetic similarity closer to about 85 percent than to 99 percent. From an evolutionary perspective, if a 99 percent genetic similarity reflects a close evolutionary connection, then an 85 percent genetic similarity distances humans from chimpanzees.
Other recent studies demonstrate that even small genetic differences (such as the presence or absence of a single gene or an altered gene structure) translate into significant biological differences. These help explain why humans stand apart from the great apes. Additionally, studies now show that gene expression patterns in the human and chimpanzee brains (and other tissues and organs) also differ. In other words, the difference between human biology and behavior and chimp biology and behavior likely depends to a large extent on the difference in gene usage, not the types of genes present. These discoveries are just the iceberg's tip. Based on the trend line, future work will likely identify other important genetic differences between humans and chimpanzees. Recent studies, for example, identified recombination hot spots in the human genome that are absent from the chimpanzee's genetic makeup." Differences in recombination affect mutation rates and biological variation within a species. Another recent study determined that the human genome has 200 times more copies of a class of noncoding DNA (referred to as Alu Yb8) than does the chimpanzee genome. I would like to get into this further but room doesnÂ’t allow.
Such discoveries may not necessarily invalidate human evolution, but they do make evolutionary explanations for human origins less plausible and more difficult to accept. From an evolutionary perspective, the scientific data indicate that substantial genetic change must have occurred within an exceptionally short time frame (5 to 6 million years at most). More problematic are the growing number of instances in which small differences in human genes produce the just-right biological effects necessary to account for profound biological and behavioral differences between humans and chimpanzees.
The complexity and the intricacy of biological systems, especially those in the brain, underscore the improbability that random mutations could bring about the exacting changes in gene structure necessary to support new biological functions, particularly when structure-altering mutations to single genes more often result in devastating diseases and disabilities. The same is true for changes in gene expression. As indicated by the data, differences in gene usage play an important role in generating the differences between humans and chimpanzees. The intricacy of gene-to-gene interactions and the biological effects manifested when gene expression is altered make it difficult to envision how coordinated and extensive changes in gene expression could occur to generate the anatomical and physiological characteristics that define humanity.
Changes in gene expression are frequently harmful and play a role in the etiology of many diseases. Each new discovery coming from genetic comparisons between humans and chimpanzees seems to weaken the case of evolution.
IÂ’m not saying evolution doesnÂ’t occur. Of course microevolution occurs. IÂ’m just pointing out the facts here with a naturalistic macroevolutionary model in the arena of research dealing with chimpanzee and human similiarities.
Evolution started very early as the genetic code has evolved several times before creating the life we know today.
