Sentences with phrase «gene evolution in»

Not exact matches

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.

How can evolution be reasonable when genes lose information when it mutates, even when they are deliberately manipulated in labs, under controlled environments?

(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.

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).

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?

Evolution deal directly with change in gene pools of a population.

``... when there is a systematic increase or decrease in the frequency with which we see a particular gene in a gene pool, that is precisely what we mean by evolution.»

Mutations are indeed not, so far as we know, selected by any overall purpose favoring evolution; but this is compatible with there being short - run and very naive purposes, desires, or feelings in the atoms and molecules constituting the genes, as well as in every cell and every metazoan with a nervous system.

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.

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.»

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.

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 samplinIn 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 samplinin conjunction with the effects of random drift composed of random variations in these pressures and of local accidents of samplinin these pressures and of local accidents of sampling.

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.

«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.
