The Dhaka Times Desk A new mystery has emerged in the history of mankind around the 16 fossils recovered from inside the cave. A strange matching of early and modern humans has also been found in the jawbone characteristics of human bodies!
After the research, the scientists claimed that this is a new species among the human species. Scientists are shaken after the recovery of such fossils from a cave in eastern China.
The findings, published in the Journal of Human Evolution, indicate that these bones are 300,000 years old. They belong to the ancient human race. However, they have not been identified as distinct species so far.
Scientists excavated the remains of at least 16 humans in a cave called Hualongdong in Anhui province in eastern China where the species lived. They were on earth about 3 million years ago. Among them is a teenager.
The first skull was described in 2019 by Jabei Wei, a paleontologist at the Institute of Vertebrate Paleontology and Paleontology in Beijing, and his colleagues. However, they were able to identify a fragment from several animal bones found the following year. It was the lower part of the jaw.
After further analyzing the discovery, they found that the Hualongdong species actually existed on Earth at some point in human history. These bones have a mixture of features of both modern and ancient species. The jawbone was thick, a feature common to the early human species Homo erectus. The upper jaw joint is slightly narrower, which is similar to the main features of modern humans, Homo sapiens.
However, Songdong University anthropologist Yameng Zhong expressed doubts about this new claim. He said, Eurasia was inhabited by many early humans. They lived there during this period from 8 lakh to 1 lakh 26 thousand years. However, there are doubts whether these newly discovered bones are of the original human species or not. -News from Nature Journal.

How to prevent dengue
Dengue is a mosquito-borne viral fever. This fever is different from other viral or bacterial fevers. However, this fever is not contagious in any way. This viral fever can occur alone or in combination with other viruses (chikungunya, yellow fever, Burma forest, flu, respiratory syncytial) and bacteria (pneumococcus).
Dengue fever is divided into two categories depending on the severity of symptoms and fever.
1. Common dengue fever
2. Dengue fever with bleeding.
In the case of common dengue fever, the following symptoms are mainly seen-
1. Sudden high fever lasting 2 to 7 days.
2. Severe headache.
3. Pain behind the eyes.
4. Along with the fever, red rash appears all over the body.
5. Severe pain in whole body as well as back pain.
6. Nausea or vomiting.
7. A rash or red bumps on the skin.
In case of dengue fever with bleeding:
1. Bleeding from nose, mouth or vomiting with high fever within 2 to 48 hours.
2. Fluid accumulation in chest or abdomen along with fever.
If any of these symptoms appear, seek medical attention immediately.
On the other hand
Wait at home for the first 3 days of fever. On the other hand, sponge the whole body with water every now and then. This will reduce the level of fever. Drink enough water and rest. After that, if the fever does not decrease or if it continues to increase after some time, consult a doctor immediately.
Things to do to prevent Dengue:
1. Try to keep the surroundings of the house as clean as possible.
2. If there are flower tubs or broken plastic bottles, can shells, tires or polythene inside the house, clean them quickly and drain the accumulated water from the flower tubs.
3. Spray or fog at least 3 times a week to kill mosquitoes.
4. You can keep mosquito repellent cream with you while going out.
5. After evening, younger and older members of the household should use mosquito nets.
6. Clean up any accumulated rain water, as this is the time when Aedes mosquitoes lay their eggs.
7. On the other hand, you can use mats along with mosquito nets to avoid mosquito infestation.
8. Since Aedes mosquitoes bite during the day, it is important to avoid sleeping with mosquito nets while sleeping during the day. Source: https://dmpnews.org
