Are we products of nature or nurture? Science answers age-old question

A group of researchers stated that human characteristics can be answered by ancient questions determined by nature and cultivation. What is their conclusion? This is a draw

By tidying up most twin studies around the world over the past 50 years, researchers believe that due to genetic factors, the average variation in human traits and diseases is 49% and environmental factors are 51% .

Beben Benyamin, a researcher at the Queensland Brain Institute in Amsterdam and a researcher at the VU University, cooperated with 2,748 studies involving over 1,450 twins.

"Twin studies have lasted over 50 years, but there are still some debates as to whether mutations are caused by genetic factors and environmental factors," Benyamin says.

He showed that the research showed that the conversation should be separated from nature and nature, not the way the two work together. "These two are an important cause of interindividual fluctuations," he said.

Although these studies averaged approximately equally between nature and cultivation, there were significant differences between 17,800 different traits and diseases studied by the study.

For example, due to genetic factors, the risk of bipolar disorder is 68%, but the environmental factor is only 32%. Due to genetic factors, the weight maintenance rate was 63% and the body weight maintenance rate was 37% according to environmental factors.

By contrast, the risk of eating disorders is known to be 40% of the inheritance, 60% of the environment, but the risk of mental and behavioral impairment caused by alcohol is 41% genetically, 59% is.

Benyamin said genetic factors are more important than environmental factors in psychiatry, ophthalmology and skeletal characteristics. However, the opposite can be said about social values ​​and attitudes.

However, Benyamin said that the contribution of genetic factors does not have a single feature. "Genetics contributes to all the features - how much is the difference?"

These studies published between 1958 and 2012 compared the similarity between identical twins that share the whole gene and non-twins that have half genes using "classical twin design" .

More closely related features in non-identical twins show greater impact of environmental factors than identical twins

More than half of the studies relate to psychiatric disorders, metabolism and cognitive functions such as depression, anxiety, psychological and behavioral disorders associated with alcohol and tobacco use, weight to height ratio

Studies of these bodies are part of a twin large-scale multicenter study. Researchers hope that twin studies will also light on ancient nature and cultivation issues - these characteristics and features are caused by heredity and may be influenced by the environment. For example, since twin telephone bodies are very similar, studies have shown that even novices can take 10 double brain MRIs into view. Therefore, researchers assumed that this part of the brain is primarily controlled by genes. However, another neuroanatomy, the cerebellum behind the head behind the neck is not very similar in the twins, so Giedd makes it presume that the cerebellum is environmentally sensitive that it is not genetically controlled.

The story of Mozart (and the story of many other planners and gangsters) shows answers to ancient nature and fostering debate. We are all products of genes and environment. So even if you look at the calm face of the newborn you are asleep, his brain is constantly developing, almost equally affecting the genetic code you and your partner acquired and the experience you provided to him It will be. Expression of these genes

In her masterpiece of 1818, Frankenstein, Mary Sherry is a story of Dr. Victor Frankenstein and the monster he created. Sherry is exploring the ancient nature and child rearing problems. In other words, we are due to genes that grew to them thanks to their growing experiences. Is our role integrated into our existence? Or was it formed by the way we raise and the way we teach us in the most mature year? The most obvious example of nature and cultivation is the relationship between Victor Frankenstein and his monsters. Victor is an excellent scientist who is excited about the prospect of using the spark of life. In his excitement, he rarely takes into account the results of his actions.
