According to the American Life Science website, in the near future, scientists hope that the news of cultivating "human-animal chimeras" is very controversial, and it is easy to remind people of the horror experiment of Frankenstein. However, in fact, chimeras are not always artificial products. There are some examples of human chimeras in real life, which are mainly divided into three categories: fraternal twins, bone marrow transplants and fetal micro-chimeras.
Essentially, a chimera is an organism composed of two or more "individuals" that contain two sets of DNA whose codes constitute two different organisms. The chimera can naturally appear in the human body, and the fetus can absorb his twins. This phenomenon occurs in fraternal twins. If an embryo dies earlier in pregnancy, some of its cells will be "absorbed" by his twin brothers.
The fetal residue will have two sets of cells, its own set of primitive cells, plus the cells of the twin brothers. Such individuals often do not know that they are chimeras. For example, in 2002, a woman named Karen Keegan, she needed a kidney transplant and had a genetic test with her family to see if the family could donate organs. But genetic testing shows that Karen is not the mother of her son from a genetic perspective. The scientists eventually discovered that Karen was a "chimera" with different DNA groups in Karen's blood cells compared to other tissues in her body.
A person may also become a chimera when undergoing a bone marrow transplant. In such a leukemia bone marrow transplant operation, his own bone marrow will be destroyed and replaced with another person's bone marrow. The bone marrow contains stem cells that can develop into blood cells, which means that patients who receive bone marrow transplants will have blood cells. In the latter half of his life, from a genetic point of view, he is a donor and his body is not his original blood cell.
The latest research report points out that there are three kinds of "chimeras" in human real life, and perhaps "chimera" is not as terrible as people worry.

What are the benefits of eating a vegetarian diet on a regular basis?
1. People who eat vegetarian food regularly will live longer than those who eat meat regularly, as Indian tribesmen live longer because of their regular vegetarian diet and many monks live longer because of their regular vegetarian diet. The fat content of sweet corn is 2 grams of fat per 100 grams, making it a low-fat product.
A single cob pack of sweet corn from Jilin Province Agricultural Sister-in-law Food Co., Ltd. is at least 220g and will provide you with at least 6.38g of protein and 4.4g of fat.
2. Corn as a vegetarian food is lower in calories than other foods of the same quality, and its fat content is almost non-existent. It provides the body with the nutrients and vitamins it needs and has no energy stores.
3. Reduces cholesterol levels. Vegetarians have less cholesterol in their blood than meat eaters. If cholesterol levels in the blood are too high, it often causes blood vessels to become clogged.
4. It reduces the burden on the kidneys. Once meat eaters eat meat containing animal blood, the burden on the kidneys is even heavier".
