Was an Insect Ancestor Discovered?

There is nothing simple about an animal group called the euarthropods (phylum Euarthropoda), which includes insects, crustaceans, and extinct trilobites.

Evolutionists stated in a recent issue of Nature how complex these alleged early creatures were: “Sophisticated brains and specialized feeding appendages, which are elaborations of serially repeated organ systems and jointed appendages, underpin the dominance of Euarthropoda in a broad suite of ecological settings.”1

A fossilized larval stage of an alleged euarthropod that evolutionists are calling Youti yuanshi was discovered north of China by a team of scientists at Yunnan University.1 Later, researchers in England mounted the fossil on the head of a pin and scanned it with X-rays. The BBC reported, “Researchers generated three-dimensional images of miniature brain regions, digestive glands, a primitive circulatory system and even traces of the nerves supplying the larva’s simple legs and eyes.”2

Evolutionists then declared that this poppy-seed-sized “520-million-year-old” fossil is “one of the earliest ancestors of modern insects, spiders and crabs.”2 That is certainly open for debate.

Where did the Euarthropoda come from? What was their origin? According to Nature, “The origin of the euarthropod body plan from a grade of vermiform [worm-like] taxa with hydrostatic lobopodous appendages (‘lobopodian worms’) is founded on data from Burgess Shale-type fossils.”1 The Burgess Shale was allegedly formed between 505 and 510 mya. Could it be that the “data from Burgess Shale-type fossils” are subjective?

In fact, the Nature authors added a note of caution:

As this phylogenetic [evolutionary relationship] framework emphasizes adult morphology, the interpretation of Youti requires a degree of caution: the absence of features such as annulations, claws, setal blades, or compound eyes, or the location of its first appendages, may reflect its ontogenetic stage [the whole course of an individual’s development] rather than its phylogenetic position.1 (emphasis added)

Evidently this tiny fossil was formed by flooding, and creationists maintain such flooding occurred only thousands of years ago.

“It’s washed into the oceans when rocks erode on land,” [lead researcher Dr. Martin Smith] said.

“And that phosphorus seems to have flooded the tissues of our fossil,” essentially crystallising its tiny body.2

According to the creation model, this Youti fossil is not a half-billion years old, nor did it somehow evolve from simpler creatures. Various illustrations (anatomical overviews) in the Nature article1 display a highly sophisticated creature caught up and buried during the Genesis Flood.
