Minute Foosals tell a big story about the arterous evolution

A small gems of a marine creature that lived more than half a billion years ago, sheds new light on the evolution of arthropids, which is the most common and successful group of animals to live in the ground, according to a research published in a research published Nature communications.

One of the last rest of the article around the arthroup -evolution is the division of the life tree, which is to separate the two largest groups of arthropids: mandilates, including insects, Christians, Milpades and centrifuges. And Chellasts, the group that includes spiders, scorpions and their relationships.

A new analysis of an endless creature of an endless creature, known as Jiangfiangia Multiwat, suggests that this pattern is very important in separating the initial mandels from challenges.

A team, led by Nicholas Strasfield at the University of Arizona’s Department of Neuro Science, revealed a minute of a minute of Jiangfenia’s gambling brain that it was not chelly, as previously assumed.

Jiangfiangia’s ranking as a native Chemistry was in the grip of his couple, spreading its head. This feature placed it in the collecting of an endless creature known as Megacherin – Grack for “big hands”.

Of the two highly reserved megacherin patterns, who lived about 525 million years ago, Jianfiangia, who also had compound eyes, and Allokinio, which had fewer classes and two couples single lenses. Both were traditionally combined with the assumption that their head supplements became the spiders and their relatives to the fungus.

According to the research team, the story is more proportional and complicated. Stragents Professor at the University of Arizona and Royal Society, Straussfield, called his discovery a potential game changer.

“There were no anticonols in these megachers, which are commonplace in crustesh, pests and centuries,” said Strasfield. “Instead, we see that these are strange, strong head supplements that specialize in reaching things and laughing.”

Experts have called the megacheren fossils “a” tremendous supplement “. Straussfield added that his pinsed heads suggested their resemblance with a laughing supplement of Lemols, commonly known as Horseshow Crab. For this reason, Megachara was classified as Chelsetes, which also belongs to Lemols and Arachinds.

This research has revealed that the Jianfiangia and Allokinius’ brain were not only morally separated from each other, but that they were not the only one to the ancestors of two major arthroup groups.

The small head of Jianfiangia, which is only two mm measurements, is defined by a short, shell covered like a shell, which has extended the couple into a “great supplement” pair.

They are just in front of the front, one side of the head, a small but obvious mixture of the eye, like insects and crustesians. In front of Jianfiangia’s head, there were at least three single lenses “eyes”, like the simple eyes found in many insects and crushes.

When the Straussfield team restructured the remnants of Jianfiangia’s nervous system in four ferocity patterns, his brain was found, which is equivalent to modern crab or curry fish. In addition, it also showed the elements of the easy arrangements shown in the small freshwater Christians, such as salty crabs, also known as the “sea monkey”, who provided many children with a real direct Christians.

Together, the results were concluded by the researchers that Jianfiangia had previously been rated as an early Chelstrate, while Allokinis had already been shown a brain like Lemols.

“Our results show that a close examination of nervous nerve remnants can provide powerful data, which shows that evolutionary relationships are impossible to achieve only with the characteristics of eczemin,” said Strasfield. “Someone needs to know what to find in the brain because it tells us a lot about the identity of the foam.”

Frank Herath, co -author and professor of Kings College of the University of London, emphasized an important aspect of the Jovashim: “His focus is completely straightforward with the alive arthropdis, which shows that his ancient genetic and developmental ingredients are unusual because of this.

In 1984, Zhengwang Ho, a professor at the Greek Cali Laboratory for Greece Laboratory for Greece, in the Chinese city of Kunmang, discovered Jianfiangia’s first gambling in 1984.

One of the most famous beds in the Cambrian era, which lasted about 540 to 480 million years ago, was once a shallow sea in the Kunmang province in Greece, China. The grace of his ancient life is rarely rarely showed evidence of soft tissues, especially neurological remnants. Since then, around a dozen additional samples have been found.

Straussfield pointed out that the nervous marks of Jovashim may be very subtle, but contrary to the darkest reservoir standing against the rocky rock, it can be enhanced by increasing the width in which Jovashim was embedded.

He said, “What we saw was unexpected: the brain looks really modern, compared to living Christians.” “In a sample, we could even peek into the compound eyes and see some aspects of it see the fossil ‘cone cells’ that supported photoshoppers.”

To further confirm the evolutionary location of Jianfiangia, David Andrew, co-author of Likoming College at William Sport, Pennsylvania used stats for the construction of so-called philosophical trees-which should make family trees based on nervous tracts, to determine the life of the Jianfia.

Andrew said, “Many of these comparisons have revealed that in the art of life, Jianfiaia was sitting at or near the root of all mandels, while its potato cousin, Allokinis, has the same status, but said in the life of the life of life.”

The team concluded that the “great supplement” belonging to Jianfiangia was later transformed into today’s essential antioxidants, while later the “great supplement” of alloominis was transformed as a Fungus -like Fengs like Today’s Chelsees.

“In the Chelseets, these” tremendous supplement “shrink, so they eventually become a spider’s feng, said Strasfield. “In the mandels, evolution turned them into class anticonols.”

According to Strasfield, living cooperation for this theory is from living astronauts, small maritime crusade sports antinals, which are indicated with laughter. “It appears that the ‘great supplement’ we see in our focus of a billion years ago were not completely eliminated.”
