The next episode I’ve heard directly from an anatomical technician

Mankind must wait at least tens of thousands of years for the final result..... When a young doctor was touching his lover’s breast, he found that she was already in the early stages of breast cancer. human cancer proliferated a certain number equal I’m not saying that all women should be intimately associated with doctors to prevent cancer. The little story I mentioned above is a quote from a novel I read, but it’s probably true. The next episode I’ve heard directly from an anatomical technician: In one study, cancer cells were artificially proliferated. The number of cancer cells in the beaker increased exponentially, but once a certain number of cells was reached, it stopped increasing. The number of cells was almost equal to the number of cells in our human body. Wow! This experimental report means that if cancer cells proliferate spontaneously without being resected in the early stages, all cells in the human body may be replaced by cancer...

Has a long nose, so dogs recognize things by smell

Now, who will sue who if evolution is wrong? .... “Dog has a long nose, so dogs recognize things by smell.” traits functions abilities evolution happened forced Someone said that. In short, the idea is that there are traits first, then functions, and then abilities. When I heard the above statement, I felt a little uncomfortable. Because it is inconsistent with evolution. We have acknowledged evolution as a legitimate reason. That’s the theory that when you ask for some ability, you spend several generations, the species gains function, and the traits change, right? If the dogs were to be explained by evolution, dogs sought a high degree of olfaction, amplified nasal function over several generations, and eventually “evolved” into a long-nosed trait. Hmmm, is that true? After all, it seems that the long-nosed creatures happened to have a high sense of smell, which forced them to recognize things by their smell. Similarly, the reason rabbits h...
