What is the research value of the discovery of new insect species hundreds of millions of years ago

An amber who sealed the "stinky big sister" 100 million years ago was exhibited at the Beijing Stone Exploration Museum on the 21st. The huge horns and long and slender body create a clear gap - this monster in Amber is the insect with the largest number of tentacles found at this stage, and biologists call it the Great Horned bug. Mites, that is, the "sister of bed insects" that everyone in the Northeast put it bluntly.

According to the research of Professor Chen Rui of the Institute of Zoology of the Chinese Academy of Sciences, this kind of amber platinum should come from the Hugang Valley in Kachin State in northern Myanmar, and its generation age is in the middle and late Cretaceous, about 99 million years ago. The insect body preserved in the amber leaf has exaggerated and delicate flexion and extension tentacles, which can accept a large number of organic chemical data signals and improve the perception of potential host plants and their surrounding environment. The bighorn bug in the amber is most likely a mimic branch, with leaves growing on the branches.

It is a distinctive and reasonable defense, much more elaborate than simply emulating deciduous and tree techniques, and perhaps it can cope with many carnivores of the Cretaceous period. This discovery is expected to provide direct evidence for the evolution of the plurality of individual insect behaviour under the theory of natural selection.

Oversized tentacles offer many benefits to insects, but why haven't they been picked for millions of years? Huang Dawei, an expert professor at Nankai University in Tianjin, said that although large tentacles can give insects the upper hand in accepting chemical information, mimicking personal behavior, sexual selection, etc., because of excessive consumption of kinetic energy, slow and dull posture, and excessive exaggeration of appearance design, it will also limit the ability of individuals and species to adapt to the transformation of work, especially when the natural environment produces major changes, and will eventually have a great adverse impact on insects.

The results of the research have been published internationally. The team said they would again look for individual nymphs of the Great Hornworm to further confirm the hypothesis of the role of this particular trait and its associated role. The collection of the amber specimen will be exhibited in Beijing.

In addition, the collection of ** specimens such as shrimp-shaped amber, annular amber and Tyrannosaurus rex feathered amber is also exhibited.

On March 20, an amber sealed with hundreds of millions of years ago "bed bug" was unveiled at the Stone Exploration Museum in Beijing, with huge horns and a slender body, forming a strong contrast - it is the largest class of insects with antennae found by human beings, and is called the great horned bug by scientists. Bugs, which are what I call bed bugs. This discovery can help biologists explore and improve the structure of genes and food chains in nature hundreds of millions of years ago, and can make people better understand the environment and the changes behind it, which has the research value of humanistic exploration and biological exploration.

This has great research value, not only for people today to understand the species of insects hundreds of millions of years ago through this new species of insects, but also for scientists to further understand the earth hundreds of millions of years ago.

This value is very great, and it can be used to study the evolutionary laws of insects in depth, which has a great development for biology.

Amber, as a work of art by nature, preserves the true appearance of many ancient creatures for us, so what is the obvious difference between the insects of 100 million years ago and the insects of today?

As the name suggests, the so-called worm amber is the amber that wraps the worm. In ancient times, insects and other creatures were wrapped in amber, and after a long time, they were discovered by humans now, but the flies in the worm were still very different from the flies of today.

100 million years ago, the fly in the worm was different from the current fly structure, the ancient fly head had an obvious protrusion, similar to an extra horn on the head, and above this horn, there are other sensory organs, because the position of the sensory organ on this horn is higher than the horizontal line of the fly, so it can better monitor the surrounding environment. And ancient flies, their antennae are also very peculiar in shape. Instead of having a linear antennae of the current fly, it has several branches, like the tentacles of an octopus in the sea, and the jaws of ancient flies are more delicately shaped, allowing for better ingestion of food.

According to the speculation of root calendarists, another obvious difference between insects from 100 million years ago and today's insects is that the insects of 100 million years ago were even larger because of the higher oxygen content in the earth in ancient times. One of the most critical limiting factors is the amount of oxygen in the air, and in ancient times, the oxygen content was much higher than it is now, and the harsh natural environment gave rise to larger insects. As for why these insects have not been preserved, it may be that the size is too large for amber to wrap, or it may be that those insects do not have hard bones, and their flesh and blood have been slowly worn away over time, and there is no way to preserve them.

So after talking about the obvious difference between insects 100 million years ago and now, let's take a look at the species that did not change between 100 million years ago and now, that is, sea turtles. Foreign biological researchers have found that the ancient turtle structure of 100 million-year-old sea turtle fossils, or sea turtle amber, is not much different from that of modern sea turtles, which may indicate that the marine environment has not changed much, so that the species has little chance to evolve.

There has been a noticeable evolution, and it looks very similar, and there has been a reduction in size, and there have been changes in color.

Their habits and ways of capturing will be different, and they have changed a lot, and their body size is relatively large.

The two are very similar in appearance, but they are not identical. Biological evolution is a process that is more adapted to the environment, and there are definitely local changes.

Scientists have discovered new species of insects in the age of dinosaurs, which is of great help to the study of species evolution. In his theory of evolution, Charles Darwin said that we are where we are today is largely due to the evolution of species. In this world, the environment is constantly changing, and species are constantly evolving.

Natural selection, survival of the fittest is the rule for every species to survive and evolve in this environment. In the change of times, many species have died out because they did not adapt to the environment, and many new species have evolved to adapt to the environment. Therefore, Chinese scientists were able to discover new species of insects in the age of dinosaurs, which also means that we can better develop the evolution of species.

There are still relatively few species that evolved in the age of dinosaurs, so if there is this discovery, it can better help to study the evolution of species. <>

As we all know, dinosaurs were very large in size, and the reason for the extinction of dinosaurs is still unknown to us. Therefore, the discovery of new insect species can greatly help us understand the environment in which dinosaurs lived and why dinosaurs became extinct. We can better compare it with modern insects by studying the insect's living environment and lifestyle, and even by extracting DNA.

This is because different DNA pieces exhibit different characteristicsThe environment in the age of dinosaurs may not be the same as the environment now, and the way the genes in the DNA are expressed is also different. <>

The discovery of new species can first of all be a good way to carry out a more in-depth understanding of the theory of species evolution, and at the same time, it can also better understand the environment in which dinosaurs lived through the relevant conditions of insects, and to understand the reasons for the extinction of dinosaurs. <>

In our lives, it is precisely because of the diversity of species that our entire ecological environment tends to a stable state. Therefore, species diversity is very important for our ecological environment.

The discovery of ancient new species by Chinese scientists has a positive role in promoting the discovery of the origin of human beings and other species, and is conducive to better research.

Personally, I think that the discovery of a new species of insects in the age of dinosaurs is likely to be of great significance to our study of the age of dinosaurs, and it is also very likely that we will learn more about the past era of dinosaurs.

This is of great significance for scientists to study the history of the age of dinosaurs. Moreover, it has greatly improved the level and status of scientific research in this regard in China.

There are giant shrimp, giant pythons, bell snails, giant squid, giant scorpions, etc., but they have gradually evolved over time, and their size is much smaller than before.

There are many kinds of insects, as early as ancient times there are traces of insects, the ancient insect family includes praying mantis, crickets, grasshoppers, cicadas, beetles, dragonflies, etc.

Spiders, scorpions, centipedes, horses and worms. Insects are very fond of eating everything, wood, nectar, comfrey, and other insects.

Foreword: Trilobita is an extinct class of arthropods.

They first appeared in the Cambrian period, peaked in the early Paleozoic, and then gradually decreased to extinction. The latest trilobite (Scallopidae) disappeared during the extinction of the biomass at the end of the Permian period 100 million years ago. Trilobites are very well-known fossil animals, probably second only to dinosaurs in their popularity.

The extinct trilobite hemiecantha subgenus, red moss, hemiecanthidae, 163 mm, from Morocco, grew in the middle Cambrian period.

The trilobite gets its name from its transverse division into a middle lobe and two symmetrical lateral lobes.

Elrathia (scientific name: Elrathia) is a genus of trilobites that live in the Cambrian ocean, living on the bottom of the continental shelf. The head of this type of trilobite is smaller than the chest.

The glabellum is small and pot-shaped, with small eyes and short triangular cheek spines growing in the center. The thorax is divided into 13 segments, with a narrow central axis and broad lateral plates, ending with a short, spiny distal. The tail is medium in size and twice as wide as it is long.

Insects are of great variety and morphology, belonging to the arthropods of invertebrates, and are the most abundant animal group on the planet, accounting for more than 50% of all biological species (including bacteria, fungi, and viruses), and their traces are found in almost every corner of the world.

Until the beginning of the 21st century, there were more than 1 million species of insects known to humans, but there are still many species yet to be discovered. Insects are the most diverse and abundant in the animal kingdom and have a significant impact on agricultural production and human health [1]. The most common are locusts, butterflies, bees, dragonflies, flies, grasshoppers, cockroaches, etc.
