Glowing Marmoset Feet!

Quite understandable how this can be done if evolution is correct, but it becomes a bit more problematic under a creationist scheme of things.

What man can do with some difficulty, but in very short time frames in a small laboratory opens a window (not that one is needed for most of the world... only the young earth creationists!) to show what nature, genetics and natural selection can do over geologically long time spans with the whole world as a laboratory.

NEW YORK – Scientists gave marmosets a gene that made their feet glow green, and one of the animals passed it along to its offspring — the first time that an added gene has been inherited by a monkey. It was a milestone, experts said, that should make it easier to produce animals with versions of human disease for medical research.

Animals that get added genetic material are called transgenic. While researchers have long created transgenic mice and other animals by giving them extra genetic material, monkeys offer a promising avenue for medical studies because of their similarity to humans.

Researchers have added genes to rhesus macaques before by injecting embryos, but the new work is the first documentation that such genes can be passed along to future generations of monkeys. That's important because it opens the door to creating colonies of transgenic monkeys by breeding, which would be far simpler than the cumbersome process of making each animal from scratch by injecting a gene into an embryo.

The work is reported in Thursday's issue of the journal Nature by scientists at the Central Institute for Experimental Animals in Kawasaki, Japan, and elsewhere in that country.

The researchers plan to use transgenic marmosets to study such conditions as Parkinson's disease and Lou Gehrig's disease, or ALS.

Anthony Chan of the Emory University School of Medicine in Atlanta said the result boosts his confidence that his transgenic macaques will also pass along their added genes to offspring, once they become old enough to reproduce.

For the study, the researchers used a gene that makes tissues glow under ultraviolet light, as an easy way to see where the gene is present. They put the gene in a virus that would insert it into the DNA of cells, and then injected the virus into marmoset embryos. From these embryos, five healthy marmosets were born. All showed evidence of having inherited the gene.

Later, one of those animals fathered a male by test-tube fertilization. The gene was shown to be active in the offspring's skin.

"The birth of this transgenic marmoset baby is undoubtedly a milestone," Gerald Schatten of the University of Pittsburgh School of Medicine and a colleague wrote in a Nature commentary.

Transgenic marmosets could be useful for studying infectious diseases, immunology and neurological disorders as well as some genetic disorders like muscular dystrophy, they wrote. But marmoset biology differs enough from humans to prevent study of other disorders like AIDS and tuberculosis, which can be approached instead through other monkeys that are more closely related to humans, they wrote.

Been reading about the glow-in-the-dark monkeys!

I suppose it could be argued this is not "true" mutation since genetic material is initially transferred. But as I understand it many such transfers occur in nature, with genetic matierial gained from bacteria and viruses.

Makes not a whit of difference whether it's a "true" mutation or not, Chris. The creationists are stuck with a massive "mutation" of a marmoset's DNA yet the animal is apparently doing well as an individual AND breeding true.

There is nothing in creation handwaving that can account for this.

Which is why they have never attempted to state creationism as a formal scientific theory because they KNOW... right down to the tips of their little creationist toes and fingers... that such a theory would not stand up under any sort of rigorous investigation. Hell, kids would be turning in 10th grade science projects overthrowing "The Theory of Creationism!"

I would hardly relate this to the theories of evolution. But it is an interesting experiment.

Whether you so relate it or not is irrelevant, don't you think?

Why do you think the experiment worked? And how does it not relate to the definition of evolution?

Way I see it is the only difference between evolution and this is man did it purposely. But he could not have done it with out the explanatory power and predictability attained through evolutionary theory.
