Why Have Alligators Not Evolved?

Why Have Alligators Not Evolved?

These creatures were smaller and more adapted to their swampy habitats.” (Evolution of Modern Alligators). This is the standard teaching of mainstream science today. But what are the actual facts?   “The fossil record does support the evolution of reptiles, although it may not provide a complete and unbroken chain of transitional fossils for all reptile lineages.”—AI search   The Bible reports that, “God created the great creatures of the sea and every living thing with which the water teems and that moved about in it, according to their kinds, and every winged bird according to its kind, and God saw that it was good” (Genesis 1:21 NIV). God created all the creatures that make their home in the water, “according to their kinds”, that is, there are barriers as reproduction, or cross-breeding. 

“Alligators are often called “living fossils”, relatively untouched by major evolutionary changes for at least eight million years, with remarkably similar ancestors already hunting swamps alongside the dinosaurs. Yet, beginning in the 1850s, the arrival of rifle-wielding European settlers into the wetlands of Florida and Louisiana drove this evolutionary line to the verge of extinction.”-—How Alligators Are Breathing Life Into Florida’s Everglades, BBC Earth, April 19, 2025 read more

Macro-Evolution Theory Upset by ‘Revived 46,000 Year Old Worm’

Macro-Evolution Theory Upset by ‘Revived 46,000 Year Old Worm’

Macro-evolution theory is revised frequently as result of new discoveries

Macro-evolution theory is the gradual change from one species to another over that is asserted to take place long periods of time. But why does the the theory of Macro-evolution constantly get revised? Scientists report they have revived an ancient worm, and have discovered that, “some processes of evolution are deeply conserved,” as reported in a CNN ARTICLE, of July 28,2023. Here is the article:

“Scientists have revived a worm that was frozen 46,000 years ago — at a time when woolly mammoths, sabre-toothed tigers and giant elks still roamed the Earth.

The roundworm, of a previously unknown species, survived 40 meters (131.2 feet) below the surface in the Siberian permafrost in a dormant state known as cryptobiosis, according to Teymuras Kurzchalia, professor emeritus at the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden and one of the scientists involved in the research.

Organisms in a cryptobiotic state can endure the complete absence of water or oxygen and withstand high temperatures, as well as freezing or extremely salty conditions. They remain in a state “between death and life,” in which their metabolic rates decrease to an undetectable level, Kurzchalia explained.

“One can halt life and then start it from the beginning. This a major finding,” he said, adding that other organisms previously revived from this state had survived for decades rather than millennia.

Five years ago, scientists from the Institute of Physicochemical and Biological Problems in Soil Science in Russia found two roundworm species in the Siberian permafrost.

One of the researchers, Anastasia Shatilovich, revived two of the worms at the institute by simply rehydrating them with water, before taking around 100 worms to labs in Germany for further analysis, transporting them in her pocket.

After thawing the worms, the scientists used radiocarbon analysis of the plant material in the sample to establish that the deposits had not been thawed since between 45,839 and 47,769 years ago.

But still, they didn’t know whether the worm was a known species. Eventually, genetic analysis conducted by scientists in Dresden and Cologne showed that these worms belonged to a novel species, which researchers named Panagrolaimus kolymaenis.

Researchers also found that the P. kolymaenis shared with C. elegans — another organism often used in scientific studies — “a molecular toolkit” that could allow it to survive cryptobiosis. Both organisms produce a sugar called trehalose, possibly enabling them to endure freezing and dehydration.

“To see that the same biochemical pathway is used in a species which is 200, 300 million years away, that’s really striking,” said Philipp Schiffer, research group leader of the Institute of Zoology at the University of Cologne and one of the scientists involved in the study. “It means that some processes in evolution are deeply conserved.”

And, Schiffer added, there are other actionable insights which can be gleaned by studying these organisms.

“By looking at and analyzing these animals, we can maybe inform conservation biology, or maybe even develop efforts to protect other species, or at least learn what to do to protect them in these extreme conditions that we have now,” he told CNN.”
