Evolutionists Try to Solve Darwin’s Dilemma By Invoking Cancer Growth

The Cambrian Explosion was an enormous dilemma for Darwin, and it still baffles evolutionists, and, as evolutionary biologist Matthew Wills acknowledges, it can give them a real headache.

Recent research has suggested that a dramatic increase in Earth’s oxygen level cannot explain the sudden diversification of animal life in the Cambrian.

A new paper published in the journal Nature Ecology and Evolution attempts to find an alternative explanation. Drawing from cancer research, they propose that the same principles that are seen in multicellularity are also seem in tumours.

As geobiologist Emma Hammarlund of Lund university puts it, “tumours are successful versions of multicellularity.

This is the basic premise of their approach.

Specifically, they tested whether the same molecular tools exploited by many tumors -- to maintain stem cell properties -- could also be relevant to the success of animals in the Cambrian explosion.
Cells with stem cell properties are vital for all multicellular life in order to regenerate tissue. For example, cells in the wall of human small intestine are replaced every 2-4 days, through the division of stem cells.

‘Hypoxia is generally seen as a threat, but we forget that oxygen shortage in precise periods and settings also is a prerequisite for multicellular life. Our stem cells are the ones that form new tissue, and they are extremely sensitive to oxygen. The stem cells therefore have various systems for dealing with the effects of both oxygen and oxygen shortage, which is clear in the case of tumors,’ explains
[professor] Sven Påhlman.”

However, even this approach fails to tackle to basic question of why animals diversified so rapidly and dramatically. Oxygen can’t explain it. And neither can tumours.

Some Cambrian animals were very complex, and some had a complex brain.

And some, for instance tardigrades, haven’t changed in “half a billion years.”

Killer Solar Flares May Have Kickstarted Life, New Naturalistic Scenario Suggests

Solar flares can certainly kill, but scientists who subscribe to the naturalistic worldview are setting their hopes on them.

Avi Loeb at Harvard University and his colleagues simulated a solar flare that hit Mars with high-energy protons. They believe this might create the building blocks of life.

Here we have a speculative scenario in which raw energy magically turns into life, as long as they are given a few billion years to sort things out.

It has the same problem as all other naturalistic origin of life hypotheses, regardless of what they invoke or rely on, for instance, meteorites, Saturn’s moon Enceladus, Jupiter’s moon Europa, a synthetic enzyme, cosmic rays or molecular midwives.

The problem is that they cannot produce life.

New Origin of Life Hypothesis Invokes Meteorites

Joel Kontinen

Naturalistic origin of life enthusiasts have set their hopes on meteorites as a likely breeding ground for the ingredients needed for life.

A paper published recently in the journal Science Advances examines the chemical composition of two meteorites that fell to Earth.

They … contain both liquid water and a mix of complex organic compounds such as hydrocarbons and amino acids,” a news release issued by Berkeley Lab says.

It might be an understatement to say that the Berkeley folks are exited:

“[The paper] provides the first comprehensive chemical exploration of organic matter and liquid water in salt crystals found in Earth-impacting meteorites. The study treads new ground in the narrative of our solar system’s early history and asteroid geology while surfacing exciting possibilities for the existence of life elsewhere in Earth’s neighborhood.

However, they might probably need to consider the lesson provided by a can of sardines, which has all the ingredients that life needs, but for some reason the contents are as dead as dead can be.

Much more than just the necessary ingredients are needed for life to suddenly pop up.

The latest scenario is no more credible than the previous (failed) ones, including those that invoke Saturn’s moon Enceladus, Jupiter’s moon Europa, a synthetic enzyme, cosmic rays or molecular midwives, or a plethora of other suggestions.

After all, life only comes from life, and it has to be created.

Duck-Sized Dino-Era Bird Found in China

It has asymmetrical feathers like modern birds. It is iridescence and colourful, just like today’s hummingbirds.

And Caihong juji ('rainbow with the big crest'), made public yesterday in a paper in the journal Nature Communications, is assumed to be 161 million years old but as its preservation is “incredible” the age might well be nothing more than wishful thinking.

Modern pigment has previously been reported in a ”150-million-year” old bird fossil, and birds are known to have flown over the heads of dinosaurs.

The authors describe C. juji as a dinosaur, though it probably looked even less like a dino than Archaeopteryx, the “earliest” true bird, which is believed to be or “10 million years” younger.

There is something fishy about its recent past. Discovered by a farmer in China's Hebei Province, the Paleontological Museum of Liaoning bought it in 2014.

In biblical archaeology, objects found by amateurs are almost always dismissed as frauds.

But when it has to do with evolution, the standard is obviously much lower.

C. juji has some mosaic-like features and some unique ones, such as asymmetrical feathers in its tail.

However, these would hardly make it into a dinosaur.

DNA Repair Mechanism Challenges Darwinian Orthodoxy

Joel Kontinen

A new paper published in the journal Genome Research challenges Darwinian orthodoxy.

Organisms are programmed with a feature called “DNA mismatch repair (MMR). It corrects mutations that arise during the replication of the genome during cell division.

While studying the plant Arabidopsis thaliana, University of Oxford researchers found out that the MMR prefers to repair genes rather than other areas of the genome.

A news release published by Oxford University states:

The study has important implications for human health, and is particularly useful for understanding the changes that occur in cells during the development of the tumors that underlie cancers. MMR-deficiency predisposes cells to become tumorous, presumably because MMR-deficient cells lack the gene protection that reduces the risk of mutation in the genes that normally suppress tumor formation.

Basically, DNA correction mechanisms falsify Neo-Darwinism. There are too many intelligent solutions in cells.

"Perfectly Preserved" Scales Show the Non-Evolution of Butterflies


Butterflies have resisted evolution for aeons.




Joel Kontinen

Butterflies are amazing creatures. While they tend to be tiny, they have superbly designed features that cause them to be excellent navigators.

What is more, the are a real headache for evolutionists, due to their non-evolution.

Darwinists used to believe that butterflies appeared “130 million years” ago, along with flowering plants but new research pushes back the date by “70 million years.”

Scientists found fossilised butterfly scales the size of a speck of dust inside ancient rock from Germany,” BBC News reports.

They used acid to dissolve ancient rocks, leaving behind small fragments, including ‘perfectly preserved’ scales that covered the wings of early moths and butterflies.”

And there were more surprises for evolutionists:

Intriguingly, they show that some of the moths and butterflies belonged to a group still alive today that have long straw-like tongues for sucking up nectar.”

Soft Eye Tissue Found in "120-Million-Year-Old" Bird

Joel Kontinen

A sparrow-sized dino-era bird found in the Liaoning Province in China could most probably see in colour.

An analysis of the 120-million-year-old bird revealed that the creature's eye tissues — more specially, its rods and cones — had fossilized in remarkable condition,” an article on Live Science suggests.

The article goes on to say:

These oil droplets are located on the tip of the color-sensing cone cells and act like a color filter on a camera lens. For example, red-colored oil droplets would cover red-sensing cone cells, allowing birds (as well as turtles and possibly dinosaurs) to see the color red.”

What is more, the “oil droplets were similar in size to those seen in living birds,” i.e. no evolution has occurred in “120 million years,” prompting Baochun Zhou, an associate professor of paleontology at the Shanghai Natural History Museum, to say the discovery "indicates that the complex optical system of cone cells had already been achieved by 120 million years ago."

There are serious problems with radiometric dating, so it might be wise not to be too dogmatic about dates that go into millions of years.

Some dino-age birds looked like today’s birds, and previous research has shown that an early bird preened its feathers, just like modern ones.
