Can open the origin of a 150 -year -old old -fashioned non -cutting pests with a single adaptation

An international team of scientists, led by the Dwana Biological Station (EBD-CSIC), has described a new generation of depression from the Australian Jurassic period, which is estimated at about 151 million years old. It represents the oldest famous member in the southern hemisphere of the Chironeomy Family. The focus shows a unique evolutionary adaptation: a procedure that allowed it to be firmly anchored on the surrounding rocks. Until now, this procedure was considered special for marine species.

The remnants of Gwashim were found in the beds of New South Wales in fish. Research published in the Journal Gondwana ResearchThe Australian Museum Research Institute, University of New South Wales, Munich University, and Messi University, New Zealand’s partnerships.

Bees from stagnant waters

“This fiancée, which is the oldest registered in the southern hemisphere, indicates that this group of freshwater animals began on the southern Super Contract of Gondwana,” a researcher at the Dwana Biological Station and the first author of the research, Victor Barnov.

The new species is named talmetomia talbrograika, which reflects the lockstrine nature of the residence in Talbaragar.

Current research includes analyzing six fossilized specimens. This mechanism, which works in maize -affected residences, was believed to be special to marine species. However, the sesame and palionological evidence from the beds of the tallage fish shows a freshwater yellow environment, highlighting phenotypic plastics shown by chironeumides.

New insights about the beginning of the family

Podonomini has long been used as a model system for the biographical study, which offers an ideal medium for describing and interpreting general patterns that rule the biological diversity and rule.

Initial views suggested that Podonomini bees originated in northern Gondwana and later spread to the Super Content Lorasia in the northern hemisphere. However, his foam record is very low due to tifamic bias and lack of studies focused on Jovash from the southern hemisphere. Later, the discovery of the old fox in Eurasia, Jurask, led to new interpretations, which shows that their origin is in Lorasia.

Now this new study provides compulsive evidence that the Podonomini sub -family may have begun in the southern hemisphere and later spread globally and spread globally.

Modern podunomy is almost completely found in the southern hemisphere and represents a classic case of vicarial distribution in South America, Australia, South Africa, and New Zealand. This biological phenomenon occurs when a geographical barrier – such as a mountain range or stream – eliminates the population of a species, forcing isolated groups to go through free evolution, resulting in new species formed. According to Swedish expert Lars Brandon in 1966, the Podonomini population experimented with the ancient superstar in Gondwana.

Limits due to lack of foam in the southern hemisphere

Although this discovery removes a significant difference in the fossil record of the lineage, a comprehensive understanding of the evolutionary history of this group is still limited due to the lack of fossils in the southern hemisphere. The majority of Podonomini fossils begin in the northern hemisphere, with only two former exceptions with documentary documents from the southern hemisphere: one from Australia’s Evosine sample and a Palosian record from India.

The Australian Museum and the University of New South Wales specialist Matthew McCarey explains, “There is a strong bias in the northern hemisphere to find and study the gems.

Messi University Professor Steve Trewk claims, “There are long -standing questions about the way and changed the geological time of the southern hemisphere by the geological time. Fossil species, such as small, delicate fresh water bugs, such as talibagar fly are fragile and our planet is fragile.”

The analysis of the fossil samples, combined with genomics, will help determine whether to disperse these pests after the breakup of Gondwana was basically inactive or dynamic. Understanding and protecting the biological diversity of modern times, the data will certainly be important.
