Egg
The first amniotic eggs appeared about 340 million years ago, while the first chicken appeared only about 58 thousand years ago.
The first chicken appeared as a result of a genetic mutation that occurred in a zygote created by two near-chickens. So the two proto-hens mated, fusing their DNA to form the first cell of the first true chicken.
What came first - the chicken or the egg: the answer to the riddle of the century is found

Can a PCR test detect coronavirus?
2023-04-14 14:37:03
Yes, a PCR test detects the presence of viral material in the body, but does not determine how contagious a person who has the virus is
In general, there are a number of factors that can cause PCR tests to be less accurate than under ideal conditions. Also, the accuracy depends on the PCR test itself - its design and quality. Therefore, of course, false positive and false negative results can occur. But if the test is given in a professional laboratory, this rarely happens. And, of course, the clinical picture of the patient is also important and is always taken into account. Doctors don't rely solely on test results. PCR tests are not perfect, but they are considered the gold standard in diagnosing many viruses. Together with an antibody test, this is the best that humanity has so far.
Everywhere they talk about PCR tests, but nowhere does it say what happened to the DNA samples taken during the PCR tests.
