How Intricate Patterns Grow in Flowers, Feathers花和羽毛如何长复杂的图案 • How does a growing flower bud or feather follicle know where to put the intricate colors and patterns on a mature flower or feather? Scientists are beginning to get partial answers. • Flower art: Imagine you’re a flower bud. You are blind, deaf, and dumb, but somehow you know how to create beautiful artwork. Through your efforts, a lovely rose, petunia or orchid will result. How would you do it? An article on Live Science suggests an amazing, though partial, answer: the bud has a map of the finished product. “The shape of a flower’s petals and leaves are dictated by a biological map hidden inside the flower’s growing bud,” according to a new study from the John Innes Centre and the University of East Anglia, both in the UK. 11/11/2014 2

How Intricate Patterns Grow in Flowers, Feathers花和羽毛如何长复杂的图案 • “They discovered that concealed maps within the flower buds are made up of patterns of arrows that act as instructions for how each cell in the bud should grow. As such, the maps essentially influence a flower bud’s cell polarity, or the functions of the cells. • The study’s findings not only shed light on why geranium petals are unlike rose petals, they also explain why an individual flower’s petals and leaves are different shapes.” 11/11/2014 3

How Intricate Patterns Grow in Flowers, Feathers花和羽毛如何长复杂的图案 • The “arrows” are made up of proteins called PIN proteins that migrate to the tips of cells. When they concentrate, a pointed leaf results. When they fan out, a rounded shape, like a flower petal results. Other proteins follow the “arrows” to cause growth in those areas. PLoS Biology discussed the paper in a little more detail. The original paper in PLoS Biology described how the growth proteins follow the “polarity field” set up by the PIN proteins. 11/11/2014 4

How Intricate Patterns Grow in Flowers, Feathers花和羽毛如何长复杂的图案 • Feather art: Bird feathers are vastly different from flower petals, but another amazing “mapping” mechanism controls their development. Feathers can contain stripes, spots, and nano-patterns that play tricks with light; see examples in PhysOrg’s coverage of a paper in Science Magazine. What turns on the dark and light patterns? The new research paper by Lin et al., “Topology of Feather Melanocyte Progenitor Niche Allows Complex Pigment Patterns to Emerge,” offers the beginnings of an answer: 11/11/2014 5

How Intricate Patterns Grow in Flowers, Feathers花和羽毛如何长复杂的图案 • “Melanocyte progenitors are distributed as a horizontal ring in the proximal follicle, sending melanocytes vertically up into the epithelial cylinder which gradually emerges as feathers grow. Different pigment patterns form by modulating the presence, arrangement, or differentiation of melanocytes. A layer of peripheral pulp further regulates pigmentation via patterned agouti expression. Lifetime feather cyclic regeneration resets pigment patterns for physiological needs. Thus, the evolution of stem cell niche topology allows complex pigment patterning via combinatorial co-option of simple regulatory mechanisms.” 11/11/2014 6

How Intricate Patterns Grow in Flowers, Feathers花和羽毛如何长复杂的图案 • By “evolution,” the authors cannot assume that blind, undirected processes create the patterns any more than they create intricate feathers themselves. They merely mean that stem cells are regulated to generate the patterns. But what tells the stem cells to differentiate according to a predetermined pattern? What created the pattern in the first place that these mechanisms execute? The explanation begs even deeper questions. 11/11/2014 7

How Intricate Patterns Grow in Flowers, Feathers花和羽毛如何长复杂的图案 • Speaking of feathers, how would you like to dive into a feather on the wing of a red-tailed hawk and see its microscopic structure? You can live this adventure, along with many others, in a new film just released in May from Illustra Media entitled, Flight: The Genius of Birds. (Click the link for trailer and ordering information.) With cutting-edge science, stunning photography, an original music score and a thoughtful narration aided by the insight of biologists, the film makes a convincing case for intelligent design. Along with the previous release Metamorphosis: The Beauty and Design of Butterflies, this new entry forms the foundation to Illustra’s new series of high-quality nature documentaries, The Design of Life. Both were produced in High-Definition Blu-ray with 5.1 surround sound. 11/11/2014 8

How Intricate Patterns Grow in Flowers, Feathers花和羽毛如何长复杂的图案 • We are very happy to co-sponsor Flight: The Genius of Birds and will be drawing attention to it all month. CEH Editor David Coppedge worked closely with the producer on scientific research and proofing, but it was the genius of the production team led by Lad Allen, with his editor Jerry Harned, working with the biologists, the animators, the composer Mark Lewis and the sound technicians, and others, who made this film a masterpiece. 11/11/2014 9

How Intricate Patterns Grow in Flowers, Feathers花和羽毛如何长复杂的图案 • The DVD is great, but if you have a good home theater, this is a film to enjoy in an immersive environment, with a Blu-ray player, a large screen and a surround sound system. Flight is the equal of secular nature documentaries—but without the Darwinism that is merely assumed by the others. It includes several incredible true stories about particular bird species. After being amazed by what you learn, and how beautifully it is presented, we are sure you will want to order extra copies of Flight to pass around. Order today! DVD ships May 14, Blu-ray on June 11. 11/11/2014 10

How Intricate Patterns Grow in Flowers, Feathers花和羽毛如何长复杂的图案 • And by all means, if you haven’t yet watched Metamorphosis, order them both! Readers delighted with the exceptional work of Illustra Media should support them financially. They have plans to augment The Design of Life series with more superb documentaries on the wonders of the living world. Nobody does it better than Illustra! Their films are reaching around the world. Be part of a team that is dismantling Darwinist materialism with clear, powerful, convincing evidence for design. 11/11/2014 11

Intact Dinosaur Skin Found找到完好的恐龙皮肤 • Some material that flaked off a fossil in Alberta was not stone; it was dinosaur skin. Discoverers were excited and puzzled: how could it last so long? • Here’s how Mauricio Barbi of the University of Regina described their discovery, according to PhysOrg: • “As we excavated the fossil, I thought that we were looking at a skin impression. Then I noticed a piece came off and I realized this is not ordinary – this is real skin. Everyone involved with the excavation was incredibly excited and we started discussing research projects right away.” 11/11/2014 14

Intact Dinosaur Skin Found找到完好的恐龙皮肤 • The reports on PhysOrg and on Nature World News focused on figuring what color the skin was. Readers who go all the way to the end of the article, though, find out the really big question: • “But perhaps the greatest question Barbi is trying to answer at the CLS is how the fossil remained intact for around 70-million years. • “What’s not clear is what happened to this dinosaur and how it died,” he said. “There is something special about this fossil and the area where it was found, and I am going to find out what it is.” 11/11/2014 15

Intact Dinosaur Skin Found找到完好的恐龙皮肤 • The fossil was found in an area described as a “robust bone bed.” Barbi claimed it’s the only 3-dimensional dinosaur skin fossil in the world. According to the articles, the skin was preserved “almost intact,” with tissues that can be analyzed: • “For the experiment, the sample is placed in the path of the infrared beam and light reflects off of it. During the experiment, chemical bonds of certain compounds will create different vibrations. For example, proteins, sugars and fats still found in the skin will create unique vibrational frequencies that scientists can measure. 11/11/2014 16

Intact Dinosaur Skin Found找到完好的恐龙皮肤 • “It is astonishing that we can get information like this from such an old sample,” said Tim May, CLS Mid-IR staff scientist. “Skin has fat and lots of dead cells along with many inorganic compounds. We can reflect the infrared beam off the sample and we can analyze the samples to give us very clear characteristics.” • They will be studying melanosomes (pigment cells) in the skin to try to determine what color the hadrosaur was. 11/11/2014 17

Intact Dinosaur Skin Found找到完好的恐龙皮肤 • Barbi promised he is going to find out what is so special about his fossil and the area in which it was found. His only hope is to abandon the millions-of-years Darwinian story. The reason the skin is intact, and its tissues can still be studied, is that it is recent—not 70 million years old. If he were to propose that explanation, though, his career would be over. So strong is the bias against Darwin skeptics (even stronger against old-earth skeptics), truth no longer matters. The primary goal of evolutionary geologists and paleontologists is to defend Charlie’s quaint Victorian myth against all the evidence the world throws at it. 11/11/2014 18

Bug-Eye Camera, Fly Robot and other Bio-Inspired Tech臭虫眼睛相机，飞仿生机器和其他技术 • Incredible advancements in technology are coming from the imitation of nature, but engineers cannot yet attain animal performance. • Look like a bug: “New Camera Inspired by Insect Eyes,” announced Science Now. If you thought insects with their compound eyes had inferior vision to ours, think that no more: • “An insect’s compound eye is an engineering marvel: high resolution, wide field of view, and incredible sensitivity to motion, all in a compact package. Now, a new digital camera provides the best-ever imitation of a bug’s vision, using new optical materials and techniques. This technology could someday give patrolling surveillance drones the same exquisite vision as a dragonfly on the hunt.” 11/11/2014 21

Bug-Eye Camera, Fly Robot and other Bio-Inspired Tech臭虫眼睛相机，飞仿生机器和其他技术 • In the Illustra film Metamorphosis, Dr. Thomas Emmel notes that butterflies have better color vision than humans. They can see from infrared to ultraviolet. And in the Illustra film Darwin’s Dilemma, we see that compound eyes existed in the Cambrian multicellular animals, including trilobites and anomalocaridids. • According to PhysOrg, the new camera has an “unmatched field of view.” Part of the challenge for engineers at the University of Illinois was to develop flexible electronics and optics that could accommodate curved surfaces. Even so, their “low-end insect eye” mimic does not reach the performance of the design that inspired it: 11/11/2014 22

Bug-Eye Camera, Fly Robot and other Bio-Inspired Tech臭虫眼睛相机，飞仿生机器和其他技术 • “Eyes in arthropods use compound designs, in which arrays of smaller eyes act together to provide image perception. Each small eye, known as an ommatidium, consists of a corneal lens, a crystalline cone and a light-sensitive organ at the base. The entire system is configured to provide exceptional properties in imaging, many of which lie beyond the reach of existing man-made cameras.” 11/11/2014 23

Bug-Eye Camera, Fly Robot and other Bio-Inspired Tech臭虫眼睛相机，飞仿生机器和其他技术 • It would appear difficult to rephrase that paragraph in Darwinian terms, since it depends on the use of concepts like design, configuration, and exceptional properties. The project caught the attention of Nature, and Science Dailytwice. The engineer’s paper was published in Nature, which noted that arthropods differ in the number of facets or ommatidia. Some ants have about 100 facets; praying mantises have about 15,000, while some dragonflies have up to 28,000. They ended by saying, “Biologically inspired schemes for adapting to different light levels are also of interest.” 11/11/2014 24

Bug-Eye Camera, Fly Robot and other Bio-Inspired Tech臭虫眼睛相机，飞仿生机器和其他技术 • Fly like a fly: A biomimetic robot that flies like a fly was reported in Science this week. It caught the attention of Nature and Science Daily. “RoboBee” doesn’t look anywhere near as sophisticated as an actual fly (and lacks digestive, neural, and reproductive systems), but Nature called it a “manufacturing marvel.” One of its designers said, “This is a major engineering breakthrough, 15 years in the making.” The little robot, weighing only 80 milligrams, has thin membranes for wings that it can flap 120 times a second, similar to a fly’s flapping rate (the engineers admitted it is only “modeled loosely on the morphology of flies”). Building a lightweight battery was one of the biggest challenges, so they had to tether it to a power source and computer with thin wire. Still, it’s “pretty fantastically cool,” an observer said for Science Now. 11/11/2014 25

Bug-Eye Camera, Fly Robot and other Bio-Inspired Tech臭虫眼睛相机，飞仿生机器和其他技术 • The engineering team faced many challenges. For instance, if the wings weren’t exactly symmetrical, it failed to fly. It “took many rounds of tweaking the design before it finally worked,” but when the team had their “Kitty Hawk moment,” they were really proud. RoboBee can only fly for 20 seconds, and wears out after 15 minutes of use. But it’s “the smallest flapping wing aircraft that has ever been built and made fully functional,” they said. The goal is to get the power supply, flight control computer and everything else on board. 11/11/2014 26

Bug-Eye Camera, Fly Robot and other Bio-Inspired Tech臭虫眼睛相机，飞仿生机器和其他技术 • They envision making swarms of these robots for search and rescue. “When you scale things down, smaller is better,” they said. That speaks volumes about the actual living fly, which not only has everything on board, but also contains digestive, neural, and reproductive systems. A fly or bee is comparatively large for insects, too (consider gnats and mosquitoes, for instance). Recently, a microscopic fairyfly dubbed Tinkerbella nana was discovered with a body length of 155 micrometers (see Science Daily for picture). That’s packing a lot of systems into a very tiny space. 11/11/2014 27

Bug-Eye Camera, Fly Robot and other Bio-Inspired Tech臭虫眼睛相机，飞仿生机器和其他技术 • Sea horse armor: In other biomimetics news, scientists at UC San Diego have their eyes on seahorses for ideas. According to Science Daily, “Sea horses get their exceptional flexibility from the structure of their bony plates, which form its armor.” The plates slide past each other. The plates can be compressed to half their size without damage. The principle behind the UCSD project is broader than one particular animal: 11/11/2014 28

Bug-Eye Camera, Fly Robot and other Bio-Inspired Tech臭虫眼睛相机，飞仿生机器和其他技术 • “The study of natural materials can lead to the creation of new and unique materials and structures inspired by nature that are stronger, tougher, lighter and more flexible,” said [Joanna] McKittrick, a professor of materials science at the Jacobs School of Engineering at UC San Diego. • McKittrick and Meyers had sought bioinsipiration [sic] by examining the armor of many other animals, including armadillo, alligators and the scales of various fish. This time, they were specifically looking for an animal that was flexible enough to develop a design for a robotic arm. 11/11/2014 29

Bug-Eye Camera, Fly Robot and other Bio-Inspired Tech臭虫眼睛相机，飞仿生机器和其他技术 • Mr. Clean cicada: The 17-year locusts are emerging from hibernation in some parts of the south this year. Live Science reported on work to understand how the bugs can stay so clean. They don’t need to stand in the rain; the structure of their exoskeleton allows the bugs to be self-cleaning, researchers at Duke University have found. “Apparently, grime can simply leap right off them, given dew.” When dewdrops merge together, they literally leap off the bugs, carrying grime with them. This also happens on lotus leaves and other “super-hydrophobic” surfaces. 11/11/2014 30

Bug-Eye Camera, Fly Robot and other Bio-Inspired Tech臭虫眼睛相机，飞仿生机器和其他技术 • “These findings not only can help explain the mystery of how cicada wings keep clean, but could also lead to improved artificial self-cleaning materials. Jumping droplets could also help remove heat from power plants, Chen said.” 11/11/2014 31

Bug-Eye Camera, Fly Robot and other Bio-Inspired Tech臭虫眼睛相机，飞仿生机器和其他技术 • Protein origami: Science Magazine published a paper about the use of proteins for self-assembling materials. A “Perspective” piece in the same issue about the project said that synthetic biology “aims to push natural biological systems in novel directions or to generate biomimetic systems with new properties.” The team from University of Bristol learned how to control the self-assembly of proteins to generate simple “cages” and patterns out of coiled-coil elements of proteins. “The assembly properties of the peptides are governed by how their folding results in the projection of chemical functional groups into space.” 11/11/2014 32

Bug-Eye Camera, Fly Robot and other Bio-Inspired Tech臭虫眼睛相机，飞仿生机器和其他技术 • Short bows: Nature mentioned the “worm-inspired adhesive” that came from following how a spiny-headed worm embeds itself in the tissues of its host. A bandage built on the principle is “more than three times as adhesive as surgical staples for affixing skin grafts.” Live Science posted “Seven Clever Technologies Inspired by Animals.” Entrants include butterflies, sharks, worms, cockleburs, beetles, geckos, and spiders. 11/11/2014 33

Bug-Eye Camera, Fly Robot and other Bio-Inspired Tech臭虫眼睛相机，飞仿生机器和其他技术 • As usual, evolution was useless in all these stories. It was only mentioned occasionally as an ideologically-driven afterthought, such as “Nature has developed and refined these concepts over the course of billions of years of evolution” (PhysOrg). Nature is not a developer! Nature is not a refiner. Nature knows nothing of concepts. Those are terms from intelligent design. The Nature paper on the compound eye begins, “In arthropods, evolution has created a remarkably sophisticated class of imaging systems, with a wide-angle field of view, low aberrations, high acuity to motion and an infinite depth of field,” but then says nothing further about evolution. 11/11/2014 34

Bug-Eye Camera, Fly Robot and other Bio-Inspired Tech臭虫眼睛相机，飞仿生机器和其他技术 • Evolution is not a creator! Evolution does not design sophisticated imaging systems with desirable properties! Tanya Lewis at Live Science dreamed, “Over time, evolution has led to some incredible developments, from the photosynthetic machinery in plants to the human eye.” She needs to awake from her dogmatic Darwinian slumbers. 11/11/2014 35

Bug-Eye Camera, Fly Robot and other Bio-Inspired Tech臭虫眼睛相机，飞仿生机器和其他技术 • The lingo that predominates in biomimetics is design, inspiration, exceptional performance. Darwinians, pack up your snake oil wagons and get out of the way of this new, popular I.D. parade. 11/11/2014 36

Detecting Panic in Evolution Articles 检测到进化文章的恐慌 • Some claims by evolutionists sound cool, calm and collected until you see them in context. • An example appeared in Science Daily and Astrobiology Magazine – a claim that life may have originated in salty, icy stalactites under the sea ice. Need “clues to the origin of life”? The article says, “Life on Earth may have originated not in warm tropical seas, but with weird tubes of ice — sometimes called ‘sea stalactites’ — that grow downward into cold seawater near Earth’s poles, scientists are reporting.” 11/11/2014 39

Detecting Panic in Evolution Articles 检测到进化文章的恐慌 • That’s a major shift toward further implausibility. From Darwin’s own speculations about a “warm little pond,” origin-of-life researchers have long claimed that heat is necessary to drive the reactions for life. That’s why some have imagined life’s origin at a hydrothermal vent, or lakes near a volcano, or at least in the open ocean exposed to sunlight. But “sea stalactites” of ice in the coldest oceans on earth? 11/11/2014 40

Detecting Panic in Evolution Articles 检测到进化文章的恐慌 • Even more desperate is the analogy the researchers of the American Chemical Society posed: these “brinicles,” as they have been dubbed, look like “chemical gardens” kids play with. They look like “children’s chemistry sets, in which tubes grow upward from metal salts dropped into silicate solution.” Being made of the wrong stuff, those structures have absolutely nothing to do with the origin of life. • From there, the article descended into rank speculation: 11/11/2014 41

Detecting Panic in Evolution Articles 检测到进化文章的恐慌 • “The analysis concluded that brinicles provide an environment that could well have fostered the emergence of life on Earth billions of years ago, and could have done so on other planets. “Beyond Earth, the brinicle formation mechanism may be important in the context of planets and moons with ice-covered oceans,” the report states, citing in particular two moons of Jupiter named Ganymede and Callisto.” • It’s safe to assume that if origin-of-life researchers had something better than this to propose, they would have proposed it long ago. 11/11/2014 42

Detecting Panic in Evolution Articles 检测到进化文章的恐慌 • NASA’s Astrobiology Institute is a worthless boondoggle that accomplishes nothing. Where is their evidence? They study planets, rocks, and possibly oceans, but there is still no evidence for life beyond Earth’s biosphere. It’s an enterprise built entirely on faith in a Darwinian ideology. Astrobiology Magazine publishes almost nothing original. Day after day they re-post press releases from other sources that say, “maybe this” and “maybe that.” Did you see the government seal of approval on the webpage? 11/11/2014 43

Detecting Panic in Evolution Articles 检测到进化文章的恐慌 • When “astrobiology” was born as a “new science” back around 1990 because of a rush to celebrate possible fossils in a Martian meteorite (since debunked), then-NASA-chief Dan Goldin convinced Congress to fund research into life on other worlds. Since then, nothing has been accomplished to find life elsewhere, and now they are so desperate they propose cold icicles “could” be environments for the “emergence” of life on other planets. Good grief. One of our readers should research how many millions of tax dollars the government has spent on this Darwinian fantasy trip. 11/11/2014 44

Detecting Panic in Evolution Articles 检测到进化文章的恐慌 • This is not to imply that many astrobiologists are not intelligent, highly-educated scientists. It’s just that their astronomy has nothing to do with biology. Detecting extrasolar planets, studying planetary atmospheres, and characterizing the nature of living creatures at deep-sea vents is all fine and good, but to imply that life “emerged” from non-living environments is supported by no evidence whatsoever. The legitimate studies of planets could have been funded without inventing a new word. Astro-biology is a fabrication, spliced out of two legitimate sciences, astronomy and biology. It is no more legit than geo-psychology or planetary sociology. Without evidence to justify its existence, it should be called astro-bio-mythology. 11/11/2014 45

Cosmologists Use Natural Selection to Explain Fine-Tuning of the Universe宇宙学家使用自然选择来解释宇宙的微调 • In a mathematical tour de farce, two Oxford evolutionists have applied Darwinian natural selection to the multiverse to try to explain why it looks designed. • A press release from the University of Oxford tells how evolutionary theorist Andy Gardner and theoretical physicist Joseph Conlon figured that universes give birth to other universes through black holes. The ones with the “fittest” parameters of physics get better at it and survive: 11/11/2014 48

Cosmologists Use Natural Selection to Explain Fine-Tuning of the Universe宇宙学家使用自然选择来解释宇宙的微调 • “Cosmological natural selection proposes that, if new universes are born inside black holes, a ‘multiverse’ of many possible universes could be shaped by a process similar to natural selection so that successive generations of universes evolve to become better at making black holes.… • ‘This idea of cosmological natural selection is controversial, and physicists have pointed out all sorts of problems with it. But we were interested in seeing if its basic evolutionary logic actually works,’ said Dr Andy Gardner of Oxford University’s Department of Zoology, lead author of the paper. 11/11/2014 49

Cosmologists Use Natural Selection to Explain Fine-Tuning of the Universe宇宙学家使用自然选择来解释宇宙的微调 • ‘We found that a general equation from evolutionary genetics, Price’s theorem, can help us to model how selection can work not only at the scale of genes and organisms but also at that of something as unimaginably vast as multiple universes,’ said Dr Gardner. ‘Our model uses maths similar to the mathematical theory underlying Darwinian adaptation in biology, which explains how the dynamics of natural selection leads to organisms appearing designed to maximize their fitness.’ 11/11/2014 50
