Content: Keep in mind the internal causes of heredity.
Golden sentence:
The difference between people is actually decided at the moment when sperm and eggs combine.
Many differences between people are related to heredity.
The child has been born, everything has been done, change what can be changed, and accept what cannot be changed-don't be too hard on life!
Feeling:
On the topic of heredity, most parents think that children can't lose at the starting line, so where is the starting line? The starting line of life is the moment when sperm and egg combine.
Parents each give a germ cell, each germ cell has 23 chromosomes, and each chromosome contains thousands of genes. The differences between people are determined by these genes, and each of us carries embryonic characteristics from two families: father and mother.
There are two main influences of genes on people: physiological inheritance and psychological inheritance.
Behavior is also hereditary, and personality is also related to heredity, but what is more important is the acquired parenting style and parents' attitude.
The brain structure will also be passed down. For example, some children in life look particularly smart and can talk in class, but they make mistakes in exams. Is it because children don't study hard? Still no head to read? By measuring EEG, we can know that there are α waves, β waves and θ waves in the left and right hemispheres of the brain, mainly depending on whether the θ waves are symmetrical. If it is symmetrical, then the child is not diligent, negligent and lazy; If the left and right are completely asymmetrical, no matter how hard the child studies, it is impossible to do well. Then why is it asymmetrical? Many of them are related to heredity. There are 10 children whose θ waves are asymmetrical in the left and right hemispheres, and 8 children whose parents are asymmetrical in the hemispheres. Also, because the child is born with the aid of a sucker, the cerebrospinal fluid around the brain will be sucked out when the sucker sucks, and the intracranial pressure will be in a negative pressure when the cerebrospinal fluid comes out. At this time, there will be some very slight changes in the brain structure, leading to brain dysfunction.
After investigating the genealogy of 977 British prime ministers, generals, writers and scientists with superior intelligence, British scientist Gao Erdun found that there are 89 fathers, 129 sons and 1 14 brothers, a total of 332 outstanding figures, and one celebrity can be recreated for every three celebrities on average; Among ordinary people, every 4,000 talents produce an outstanding person-it follows that "ordinary ability" is hereditary. When investigating 30 families with artistic ability, it is found that 64% of the children in these families also have artistic ability, while in 150 families with artistic ability, only 2 1% of the children have artistic ability, so it is concluded that "special ability" is also inherited; He also used the data of 80 pairs of twins to prove that people's hearts are completely inherited by examples of psychological characteristics of twins relative to other brothers and sisters.
The first rule of eugenics: to find a partner, we should "choose a good spouse" and finally "improve the race". However, the growth of children is shaped by heredity and acquired experience. Genes will provide a grand blueprint for the development of the brain, and determine the timetable for the increase, pruning and shaping of neural pathways, while early experience and acquired education will determine the formation, pruning, retention and strength of neural pathways, providing a basis for future study, behavior and health.
