Not sure what you mean by «genetic information», but evolution requires changes in the genes of the next generation of organism, which is exactly what happens with gene duplication, transposition, etc..
better yet why not hold Medel in highest esteem as his work in genes lays the true foundation for the Modern theory of Evolution, which owes much more to gene theory than Darwin's.
Biologists define evolution as a change in the gene pool of a population over time.
(insert your own, southerners backwoods joke here) So Mendel fails, in my mind, to adequately account for the very narrow gene pool (read single - celled organism) that the theory of evolution begins with.
@DOC in addition to what we know about immunology in animals and humans, what you described concerning bacteria is precisely the definition of adaptation and not evolution, the gene already exists!

Focusing on schizophrenia as a particular exemplar of this change, Luhrmann examines the evolution of psychiatry from psychoanalysis (mental illnesses are caused by emotional conflict) to a purely biomedical scheme (mental illnesses are caused by genes) to present theories, which incorporate both the biological and the social causes (and treatments) of mental illness.
(Answers: 1) because they lived and died millions of years before humans and extant forms; 2) because humans and dinosaurs never coexisted; 3) this simply didn't happen, but the creationist response is apparently, and ironically, «hyper - evolution» from severely bottle - necked gene pools; and 4) because we share a common ancestor with egg - laying organisms)
All the theory of evolution says is that life forms adapt to changes in the environment over time; that there are global changes in the gene pool of a given population of animals over time.
The real point of evolution is HOW these differences allow the individual to have more success at passing on thier genes (getting laid) which in turn creates lineage of those traits.
A common way to use the term evolution is simply to describe the change in the gene pool of a population over time; that this occurs is an indisputable fact.
And like Evolution, the Theory of Mechanics has been supplanted by more complex and more accurate theories (in the case of Mechanics, both Quantum Mechanics and Relativity have arisen to deal with its flaws; in the case of Evolution, the technical theories - such as gene borrowing and virus - guided genetic drift - do not have catchy names).
A) Technically yes, since evolution includes breeding and the passing of genes.
From the progressive order of the fossil record, phylogenetic analyses confirming these relationships, to observable instances of speciation and molecular artifacts like our gene for egg yolk protein, the evidence firmly supports evolution.
Furthermore, despite the claim that evolution has no application, phylogenetic comparisons of humans and other organisms allows us to identify the precise location and putative function of genes responsible for developmental disorders.
Perhaps the most significant distinction between evolution and ID / creationism is evolution's ability to explain poor design features, e.g. male nip - ples, the recurrent laryngeal nerve, the presence / location of endogenous retroviruses, and (one of my personal favorites) the presence of a defunct gene for egg yolk protein in our placental mammal genomes.
What I'm really going to do is to rid the gene pool of its 10,000 worst contributors, in an effort to speed up the evolution of the human race (yes: I made the system automatic, so that I didn't have to bother diddling with it at every moment: Darwin was right, but the process turned out slower than I expected, and I got bored, hence the urge to speed things up a tad).
Very well, Chad, be the former and lay out your explanation for how theistic evolution works, including the mechanisms by which God intervenes in the world of gene frequencies, the physical process by which God «orchestrates» the universe, and the observations that this understanding is based upon.
A number of time I have offered Chad the opportunity to present his explanation for how theistic evolution works, the mechanisms by which God intervenes in the world of gene frequencies, and the physical process by which God «orchestrates» the universe.
If Chad and others argue that naturalistic evolution must be dismissed because we don't know exactly what happened with gene mutation and transmission frequencies during particular periods of rapid change, then how can we accept a replacement argument in which we don't even know what happens at all?
If you search the Coursera website on «evolution», you will see that «Evolution: A Course for Educators» taught by instructors from the American Museum of Natural History» and «Genes and the Human Condition (From Behavior to Biotechnology)» taught by professors at the University of Maryland both startevolution», you will see that «Evolution: A Course for Educators» taught by instructors from the American Museum of Natural History» and «Genes and the Human Condition (From Behavior to Biotechnology)» taught by professors at the University of Maryland both startEvolution: A Course for Educators» taught by instructors from the American Museum of Natural History» and «Genes and the Human Condition (From Behavior to Biotechnology)» taught by professors at the University of Maryland both start in June.

Evolution deal directly with change in gene pools of a population.
Evolution was not of major interest to most of these biologists, but insofar as they had a theory of it, it was a theory in terms of mutations of individual genes, carried by individual organisms and submitted to natural selection.
Through cultural evolution we take charge of much of our environment and that in turn changes the direction of natural selection of genes.
But still most people would tend to agree that a program of controlled eugenics that involved exterminating humans with defective genes is immoral even though it could accelerate evolution an better the species.
You see evolution is defined as «change in the gene pool of a population from generation to generation by such processes as mutation, natural selection, and genetic drift.»
I think that the theory of evolution is all the more solid for continually routing out fossil hoaxes, accounting for uncomfortable facts, and withholding rash speculation as the genetic map adds the proof of gene tracking through the species.
At the heart of your Behe article are two concessions which simply don't support ID: 1) the ability of evolution to produce functional novelty via gene duplication / mutation and exaptation exists; and 2) that evidence of «new information» in the form of «new Functional Coded elemenTs, or «FCTs»» also exists.
So no, such a scenario does not refute evolution, but can be explained only by evolution, once we understand that the relation ship of genes to traits is not one to one, but many to many.
In this paper, I tried to interpret evolution as a continually shifting balance, spatially and temporally, among what I called the pressures of mutation, selection, and migration on gene frequencies, in conjunction with the effects of random drift composed of random variations in these pressures and of local accidents of sampling.
Swift maintains that evolution occurs, but is limited; that many cases of evolution of species have been observed, but these can be explained by gene segregation guided by natural selection.
For instance, one admits that in much of evolution (probably all above the bacteria), evolutionary changes involve enormous numbers of genes, rather than a selection of one or two particular genes (although that occurs in a few instances, possibly, for instance, in industrial melanism).
Evolution occurs at the microscopic level by changes in genes as a result of the survival of the most adapted organisms for the environment in which they live.
In 1953 with the discovery of the double helix of the DNA molecule, which led to the eventual decoding of our genes, we now have access to what would seem to be the basic mechanism through which evolution occurs.
If the young are threatened, evolution was claimed to make more of them to pass on the genes, or make them bigger, better....
It is a term used by people grasping at straws to continue dismissing evolution even as the evidence builds faster than ever at the gene sequencing level (ie, most of you agree that drug resistant bacteria have evolved but the term MACRO evolution is misused intentionally so you could continue to dismiss science to save faith; pun intended).

As Schlötterer explains, «Some genes last for a long time through the evolution of species: these are known as conserved genes.
«Identifying which of these candidate genes actually causes variation in responses to cold snaps will give us the potential to understand whether evolution to climate change can occur in both wild and domesticated animals, allowing us to better predict which species or breeds will be «winners» and «losers» and to better mitigate the effects of anthropogenic climate change on a wide range of organisms from beneficial pollinators to invasive pests,» said Theodore Morgan an associate professor of evolutionary genetics in the Division of Biology at Kansas State University and senior author of the study.
It appears the vertebrate src gene has survived long periods of evolution without major change, implying that it is important to the well - being of the species in which it persists.
The spontaneous appearance and disappearance of genes enables organisms to adapt rapidly to their environment and helps drive evolution.
