Fossil spores on land pushed back 20 million years

The big story here isn’t about the disconnect between molecular and fossil data; it’s about how early on more complex life forms got started (all that complexity in such a short time isn’t looking good for random mutations). Read More ›

Botanist Margaret Helder asks: How can a “simple” or “primitive” sponge surprise engineers with its optimal physics?

Helder: A team of Italian and American scientists researching this topic declared that the sponges display “exceptional structural properties” which enable them to thrive. In fact, their study reveals “mechanisms of extraordinary adaptation to live in the abyss.” Read More ›

What we have learned from ancient brains is that evolution did not happen to them

Researchers: Even to the untrained eye, a comparison of the fossil’s nervous system with that of a modern horseshoe crab (below) leaves little question that the same structures are found in both species, despite them being separated by 310 million years. Read More ›

Oldest continuous human habitation pegged at Wonderwerk, 1.8 million years ago

ScienceAlert: "the new findings are now thought to be the earliest sign of continuous prehistoric human living inside a cave – with the use of fire and tools in one fixed location indoors." Funny how our ancestors get smarter every time we look at them. Read More ›

Researchers: Microbes have been “at an evolutionary standstill” for 175 million years

Researcher: "The best explanation we have at the moment is that these microbes did not change much since their physical locations separated during the breakup of supercontinent Pangaea, about 175 million years ago," Stepanauskas said. "They appear to be living fossils from those days. That sounds quite crazy and goes against the contemporary understanding of microbial evolution." Read More ›

Researchers: Huge coelacanth fish is “not a living fossil”

For all practical purposes, the coelacanth is a “living fossil,” in the sense that it is an example of stasis. It wanders a bit genetically over millions of years but doesn’t change much over hundreds of millions of years. Could we say the same of most vertebrates? Read More ›

Has the Smithsonian converted to creationism about crocodiles?

At the Smithsonian: Surviving crocodiles did not change throughout millions of years because they arrived at an equilibrium where they were efficient and versatile enough that they did not need to evolve to exist, reports the Conversation. Read More ›

Primate visual systems “totally indistinguishable” after 55 million years

"55 Million years of separation on different continents is a very long evolutionary path to travel. I would have expected some mix of general similarity and characteristic differences between species in these neural modules. But the fact of the matter simply is: It is practically impossible to tell them apart." … It sounds a lot like a designed system. The basic core of the hardware and software hasn’t changed in 55 million years. Read More ›

A University of Arizona prof works hard to make Darwinism coincide with the history of life

She does a good job of pointing out how much of the history of life is really stasis. But then what about Darwin's claim about nature daily, hourly adding stuff up, subtracting the bad, retaining the good... Apparently not. Read More ›

Trilobites at 429 mya had eyes like bees

Note that we are told that the find “helps track the evolution of eyes and vision in arthropods over time” but in this case, it appears that their wasn’t much evolution: They “developed apposition compound eyes during the earliest evolutionary stages of the group and stuck with this design throughout their history.” No matter the history, Darwin must be placated.

It turns out that we all need those zombie microbes that live indefinitely and don’t really evolve

In the words of one researcher, “Our concept of how cells evolve goes out the window for this incredibly large biosphere.” And yet, we are told, “these almost-but-not-quite-dead cells play an important role in the production of methane, the degradation of the planet’s largest pool of organic carbon, and other processes.” Read More ›
