    I know that crossbreeding with closely related species will introduce new genes into an organism - most economically used plants are hybrids anyway. Plants in general seem to be quite forgiveable when it comes to hybridization, differently than for instance mammals, which mostly don't even generate viable offspring if you try to crossbreed, and if they do, then the offspring ist almost ever infertile even after crossbreeding closely related species.

    It is still a different mechanism at work than GM. A hybridized plant, while often fertile, will not yield seeds that produce the same hybrid again, it will mostly produce something similar to the wild plants the hybrid comes from. You can't grow a Golden Delicious apple tree from the seeds in a Golden Delicious. What you will get is a crap apple tree. Hybrids are a mixture of chromosomes from different species, and if you try to breed them, they will split up into their original species again. Getting hybrid seeds out into the wild thus is quite unproblematic.

    GM is different. The new gene is directly inserted into the DNA. And it will survive further breeding at its place, if the designer of the GMO has not added Terminator functionality to prevent breeding. The piece of DNA that was introduced via the gene vector can get loose again (the retro virus which carried it into the DNA is still embedded there), and then infect other organisms - not necessarily of the same species. This does not happen with crossbred organisms. You could create superweeds just by having several different strains of GM plants in the same region which are genetically modified to be resistant against different types of weedkillers.

    I don't say GM is bad (you seem under the impression I would, which explains the tone of your reply), I just want to point out that putting crossbreeding and GM in the same camp is a fundamentally flawed argument - because they are fundamentally different.

    But the Archaeopteryx is a theropod (actually, it is a paravus, which makes it a maniraptor, which in turn are theropods). Thus your argument does not hold.

    And yes, the Archaeopteryx is not a bird, but an extremely close relative to the first bird. The paraves include the aviales, which are "the birds".

    There is a small but important difference between crossbreeding and GM. In general, crossbreeding does not affects the genes, just the allels (the actual expression of a gene). Crossbreeding shuffles allel combinations, and you then can select from the filial generation the ones most close to your breeding goal and continue. But you introduce no new genes into the living. Even crossbreeding between species does not affect genes too much, as two releated species have more than 99% of all genes in common (e.g. the chimpanzee and the human have 99,7% of all genes in common).

    GM introduces genes which come from completely different strains of life. Mainly, one introduces genes from bacteria into plants or animals or vice versa. The most common technique to achieve this are gene vectors. A retro virus acts as a DNA shuttle. It gets the bits of DNA which should be introduced into the host, and then the host's cells are infected with this retro virus. It unloads its DNA freight into the genome of the host by introducing all its own viral genome and the DNA bits into the host's DNA. Then it starts to replicate using the normal DNA replication mechanism of its host, which then produces identic copies of the retro virus including the additional DNA. The normal immune answer of the host kills off the virus, but hopefully the bits of DNA it introduced into the host cell's DNA stay there and get replicated when the cell multiplies, producing the same protein(es) it did in its original organism.

    One could thus compare crossbreeding roughly as editing config files and fiddling around with parameters, and GM with actually patching the binaries.

    I don't know how the GM luddites come into play here, as there is no GM at work. It's just cells multiplying, and no single gene gets modified in the process.

    If we really want to be pedantic, the operating system is the kernel and the drivers, and everything else is an application. In my CS course (long, long ago), an operating system was defined as "the program that manages all computing resources and makes them available to the applications". There are some special applications coming with most operating systems, and they are called "shell" (and can be a command line or a GUI or whatever you want to use), whose task it is to allow a user to start, control and stop applications, but they are not part of the operating system.

    Non-traditional houses means you don't have any experience how this construction will be in shape in five, ten or fifty years time. But normally, houses exists that long. And the regulations in place try to make sure of that. Constructing houses is a complex problem, and each new construction might have hidden problems which only appear after a few years. I remember the breaking down of the roof of a ice skating hall here around, where several factors contributed to the accident (which left about a dozen people dead).

  18. Re:IT the bottleneck? on Software-Defined Data Centers Might Cost Companies More Than They Save · · Score: 1

    It's not that easy. Each road that addresses traffic congestion somewhere and is really able to ease it, actually lowers traffic costs on this relation. And if traffic cost decreases, transports that where inefficient and/or too costly before now become economically feasible. Thus more traffic occurs, until the costs due to additional traffic congestion rise high enough to stop further traffic increases. That's the Jevons Paradox, that was mentioned in the article, applied to traffic: adding new roads to ease congestion problems might cause more traffic congestion.
