Fossil tintinnids from 635-715 mya “could have been floating about hundreds of millions of years earlier”

Here’s Physorg on those recently found tintinnids from 635-715 million years ago. In “New fossils reveal oldest known ciliates” (November 16, 2011), Jennifer Chu reports, Anyone who has taken high school biology has likely come into contact with a ciliate. The much-studied paramecium is one of 7,000 species of ciliates, a vast group of microorganisms […] more

Why do some life forms never really die?

“Foraminifera estimated 715 million years old that had to endure the so-called “Snowball Earth” period when the Earth was covered in ice ” more

David Tyler: Rodents evolve – but does the evidence suggest phenotypic plasticity?

Where stasis is an exception, not a rule, “adaptive evolution” is not a convincing explanation. more

Cycads are not living fossils? As often claimed?

“Although the cycad lineage is ancient, our timetrees indicate that living cycad species are not much older than ~12 million years.” more

Can a creature be a living fossil if it was never a fossil?

If the suggestion to reclassify living fossils as “durable species” were followed, it might be harder to justify this decision. more

Tiger skull from 2.5 mya: Evolution “got it right”? Actually, unacknowledged stasis

“The National Evolutionary Synthesis Center’s Meachen said the skull’s similarity to those of living tigers and jaguars is more striking than the differences.” more

Bacteria thrive on land 100 million years earlier than thought? Oxydizing minerals, just like today?

“The researchers say the modern analogue for that first primitive oxygen-dependent life form on Earth is still with us.” more

Older than thought: Lacewings at 120 million years ago

“Seems that at this rate of evolution, we’d need trillions of years, maybe lots more, to see any substantial change.” more

Oldest found insect is – are you ready? – 400 million years old

And you’re not tired of hooting at Darwinism yet? Nor are we. more

We need a new name for living fossils like this

If it’s living, it’s not a fossil, or anyway, we don’t know it as one. We know it as a living organism. How about “durable species”? more

A handy guide to the evolution that never happened much

Some people wonder why life forms just appear and then nothing much happens for hundreds of millions of years. That’s a key reason there is a controversy around evolution. more

300 mya Harvester: “The fossil record is proving to be less and less Darwinian as we examine the details.”

Most significant is the pattern of animal and plant radiation that we find in the fossil record. Darwin predicted a branching bush or tree – but this is not what we find! more

For daddy longlegs, evolution never happened, it seems

Evolutionary biologists have been engaged in defending Darwin for so long that most of the picture of evolution is missing – because most of evolution isn’t really about Darwin or his theory. more

800 million year old shelled fossil found in Yukon, Canada

In “Yukon fossils reveal oldest armoured organism” (CBC News, Jun 13, 2011), we learn, … 800 million-year-old fossilized evidence that organisms were trying to protect themselves by forming their own shield-like plates.It is the oldest evidence ever of biomineralization, the use of minerals by a living thing to form a hard shell, similar to the […] more

Remember those primitive people who had no words for numbers?

Which shows how number sense evolved? Forget them. In “Geometry skills are innate, Amazon tribe study suggests,” (BBC News , 24 May 2011), Jason Palmer reports , Tests given to an Amazonian tribe called the Mundurucu suggest that our intuitions about geometry are innate.Researchers examined how the Mundurucu think about lines, points and angles, comparing […] more

Three foot killer shrimp of the Cambrian surprise scientists

At MSNBC (5/25/20), Charles Q. Choi tells us “Bizarre shrimp-like predators grew larger and survived longer than thought”: The creatures, known as anomalocaridids, were giant predators (ranging from 2 to possibly 6 feet in length) with soft-jointed bodies and toothy maws with spiny limbs in front to snag worms and other prey. [ ... ] […] more

Living fossil birch mouse

In “Birch Mouse Ancestor Discovered in Inner Mongolia Is New Species of Rare ‘Living Fossil’”, we learn that tiny fossil teeth (ScienceDaily May 25, 2011)” found in Inner Mongolia are “a new species of birch mouse, indicating that ancestors of the small rodent are much older than previously reported”:17 million years old as opposed to the previous […] more

Spider in amber is 49 million-year-old member of living genus

Further to “Recent Uncommon Descent posts reveal starkly different standards of evidence out there” (Uncommon Descent, 18 May 2011), this ScienceDaily story (May 18, 2011) about a trapped spider is instructive: Imaging Technology Reveals Intricate Details of 49-Million-Year-Old SpiderScientists have used the latest computer-imaging technology to produce stunning three-dimensional pictures of a 49 million-year-old spider […] more

If it ain’t broke: Lamprey unchanged after 360 million years

This blast from the past is still a source of ruinous commercial fish losses. Because lampreys do not have bone or any substantial cartilage, they are extremely rare as fossils. This fossil not only reveals a nearly complete soft tissue impression, but it also pushes back their fossil record another 35 million years. File under: Someone […] more

New book: Evolution has to happen!

This point is apparently made in Cameron M. Smith’s The Fact of Evolution: Walking the reader through the steps in the evolutionary process, Cameron uses plenty of real-world examples to show that not only does evolution happen, it must happen. Cameron analyzes evolution as the unintended consequence of three independent facts of the natural world […] more
