Chickenosaurus: Building a Dinosaur from a Chicken

As long as DP'ers are talking about dinosaurs and humans living together, it should be pointed out that modern birds are decedents of dinosaurs.

Furthermore, scientists have identified that there is an "on/off switch" within genes that can activate or repress previous physical traits.

As an organism evolves over time, they do not "lose" previous physical traits. Instead, those traits stay within the genes, but somehow the switch is turned off.

Scientists have figure out out to turn back on some of those traits. At least, when it comes to chickens.

They have been able to switch on certain traits so that chickens start to grow teeth, long tails, and scales. In other words, they revert back to their dinosaur physical traits.

This video explains the science of evolution, and is also funny and entertaining:

P.S. Yes, humans live with dinosaurs -- not back in the day with T-Rex, but today with birds.

Chickenzilla , feed the world with foul.

Then it will be a "foul world". I love these TED talks it`s kinda like listening to a mocking bird with his foot hung.

It is hard to imagine a more stupid or more dangerous way of making decisions than by putting those decisions in the hands of people that pay no price for being wrong.

Can you provide a source for that? From the reading I've done, I have determined this will be attempted. But up til now, they haven't even produced a very sick chicken, let alone a dinosaur.

But up til now, they haven't even produced a very sick chicken, let alone a dinosaur.

They've found a that can cause chicken embryos to start growing alligator-like teeth, although the mutation is fatal. Perhaps that qualifies as getting to the sick chicken stage?

Yes I read about this when

Yes I read about this when trying to verify the OP's sensational claims.

It is interesting but doesn't demonstrate that it's possible to revert an organism to a previous state in its ancestral past by destructively "knocking out" genes.

Whether prior states in an organisms ancestral past are contained in its current genetic information and subject to ordered tweaking in a corporate way seems highly speculative at this stage.

It is surely not demonstrated by the presence of teeth in a chicken with a fatal mutation. To present that to the public as proof positive of the ability to create dinosaurs from chickens is just hype and sci fi marketing.

Of course not everyone jumps to the conclusions of the OP, but probably many do jump to such conclusions by the misleading phrasing and imagery of those doing the marketing.

A lot of hype

I doubt that the scientists doing it believe they'll produce a chickensaurus simply by tweaking a few chicken genes. The fact that birds have dinosaur ancestors doesn't mean that the chicken genome and the dinosaur genome differ just in turning some genes on and off.

But having dinosaur ancestors means that chicken genes are adapted from dinosaur genes, so discovering a dormant mechanism for making dinosaur-like teeth is a great start, not for making chickensaurus but for understanding how birds evolved. I assume the chickensaurus hype is an attempt to attract funding and stir up interest.

On Darwinism, all creatures

On Darwinism, all creatures share a single or a few single celled organisms for their common ancestor. Naturally the details are murky. So postulating common ancestry does nothing to indicate a continued presence of genetic information to any specific degree. Or the ability to recreate or extract it. It has no bearing on the feasibility of producing ancestral traits in purported descendants.

Marsupial wolves have a common ancestor with marine sponges, right? So shouldn't this method work to produce traits of the common ancestor? Not if the information is lost. The fact that birds might have genetic information for teeth tells us precious little about dinosaurs, without adding heaps of speculation.

My guess is scientists are hoping to get a mutant with enough of reptilian exterior to get their names in some journals.

Who knows, maybe in a few decades they'll be able to get dogs with scales. Until they understand the mechanics of what's happening in the gene they have no right to be claiming this is demonstrative of how bird ancestors or dinosaurs teeth were.

Don't get me wrong, I find this stuff very interesting and have a strong layman's interest in epigenetics and new developments in genetics. I just also know that, like you said, disreputable and gimmicky marketing methods are being used to popularize this stuff among the public.

And since in their appeals to a befuddled democratic public with low intellectual propensities, they are often making or support philosophical and metaphysical claims beyond their paygrade, it is good to sometimes just say stick to what the science shows and stop making statements beyond the science, whether to dazzle the populace or to ingratiate your science with ideological orthodoxy.

Stick to the science, geeks.

Cool

Something to think about.

Birds are not cold blooded yet dinosaurs are said to be? Not that I am saying anything against it, but its not something thats really mentioned much or at all.

To climb the mountain, you must believe you can.

Recent research

Evidence that dinosaurs were warm blooded has been accumulating since 1870.
