Like tiny automatons, the cells that form a fish embryo's eyes are chemically programmed to individually amass at the site where the eyes will develop, according to a new study that contradicts traditional views of how organs develop before birth.
The study was done only on fish eyes and might or might not apply to humans.
"We think organs might be forming by the individual movement of cells," says Martina Rembold, of the European Molecular Biology Laboratory and the study's lead author.
Scientists previously thought that the eyes formed as cells at the sides of the tube-like structure that eventually forms the embryo's head and brain collectively bulged outlike blowing up the ears of a Mickey Mouse balloon, Rembold said. But she and her colleagues learned that the cells actually independently travel from the center of the tube out to the site of eye formation.

Of course not. Most people's limited thinking doesn't even compare with the genius of science.

Watches are complicated configurations of matter. They don't assemble themselves. They are assembled by a person.
The human body and the universe around us are complicated configurations of matter -- more complicated than any watch. They don't/did not assemble themselves. They are/were assembled by a Person.
1. For every work of art there exists an artist who created it.
2. The universe is a work of art.
3. Therefore, there exists an Artist who created it.
...at which you evidently sneer.
Well the title doesn't say "Fish Embryos." Thus it comes off sounding like a rather (if I may say so) UNSCIENTIFIC generalization.
Please prove assertion #2.
Please prove you aren't less art than a toad.

UC Riverside researchers have discovered a new way in which nature creates complex patterns: the assembly of molecules with no guidance from an outside source. Potential applications of the finding are paints, lubricants, medical implants, and processes where surface-patterning at the scale of molecules is desired.
Spreading anthraquinone, a common and inexpensive chemical, on to a flat copper surface, Greg Pawin, a chemistry graduate student working in the laboratory of Ludwig Bartels, associate professor of chemistry, observed the spontaneous formation of a two-dimensional honeycomb network comprised of anthraquinone molecules.
The finding, reported in the Aug. 18 issue of Science, describes a new mechanism by which complex patterns are generated at the nanoscale 0.1 to 100 nanometers in size, a nanometer being a billionth of a meter without any need for expensive processes such as lithography.
"We know that some of the most striking phenomena in nature, like the colors on a butterfly wing, come about by the regular arrangement of atoms and molecules," said Pawin, the first author of the paper. "But what physical and chemical processes guide their arrangement? Anthraquinone showed us how such patterns can form easily and spontaneously."
Over a span of several years, Bartelss research group tested a multitude of molecules for pattern formation at the nanoscale. The group found that, generally, these molecules tended to become lumps, forming uninteresting islands of molecules lying side by side.
Anthraquinone molecules, however, form chains that weave themselves into a sheet of hexagons on the copper surface, forming a network similar to chicken wire. The precise shape of the network is governed by a delicate balance between forces of attraction and repulsion operating on the molecules.
There is no question that the eyes form out of tissue that is already there. The question is whether the existing tissue is brain stuff or skin stuff or a lining between the two. This proposal is that the eyes form out of a combination, which seems likely since the eyes have both a direct connection to the brain and are structurally a connective tissue with cysts.
2. Some natural processes are not fully understood by humans.
3. Human brains, faced these phenomenon, 'filled in the gaps' with magic.
Ah, yes. Although I suspect that honeycombs are more comparable to crystals, with their regular shapes, than to a swarm like these proto-eye cells in the article. But the general point is the same: Complex patterns developing from relatively simple rules.
or are you suggesting that it took NO-intelligence to develop the "boids" computer models
The point is that complexity can arise out of simplicity. Organic chemicals have a high propensity to stick together in interesting ways, which are basically governed by relatively few chemical bonding rules.
The question is, is there enough complexity built in to organic chemistry's rules to generate the kind of dynamically organized - yet complex - systems that make up living organisms? I think it's intuitively obvious that there is, and so there's no compelling reason to postulate an extra intelligence that has to keep tweaking it to get it all to work.

One man's art is another man's pornography.
A little stronger: complexity is inevitable no matter how simple the start.
if its so "simple" an intelligent woman as yoursef surely could out create a complete lack of intelligence.
yes, funny these claims of "simple" yet the collective human intelligence, can come up with anything close yet.
can't
Rev Paley came up with many analogies besides the Watchmaker. But, proof by analogy doesn't fly anymore; might as well go straight to revelation. But, the Text is the word of revelation, and funny thing is it doesn't support some real basic dogma such as that the universe was created out of nothing. Not even 2 Eccl 7.28, if you have that book in your bound copy.
