Evolution in isolation

Biological evolution takes a long time. Scientists claim that the evolution of Humans from the common ancestor shared with apes has taken around 1 million years. Ever thought if a pocket of humans were isolated whether they would have different features from us.

Would we seem normal to these humans? What would we call these mutations?

A group, who live in Salinas, an isolated village in the south-western Dominican Republic, suffer from a genetic deformity that has stunned scientists. Despite appearing to be girls at birth, they are biologically male and only when they approach puberty do they develop male organs.

It is not until puberty, when another large surge of testosterone is produced, that the male reproductive organs emerge and their voices deepen. What should have happened in the womb, happens around 12 years later.

For many centuries it seemed obvious that since people look like they are designed they must be designed. Life is an illusion of design. Evolution works by copying high accurate information from generation to generation through genes. As generations go by the genes get passed on by reproduction.

Imagine if Humans had evolved to only reproducing at the age of 50. Life would be very different. Only the humans that would live up to 50 would survive to reproduce. The average age would go up among other things. Would the population of the planet be smaller?

All life on Earth evolved from a single-celled organism that lived roughly 3.5 billion years ago, a new study seems to confirm. The study supports the widely held “universal common ancestor” theory first proposed by Charles Darwin more than 150 years ago. A question asked by most people is how can Humans evolve from a single cell to what we are today. A simple answer is 9 months. Think about it!

Have you ever thought of the fact that nature played a low-down trick with those who were born and developed in isolation? Currently, there are a great number of scientific discoveries on this issue. They mention the general negative consequences of isolation for  humans such as decreased memory abilities, lower concentration, damage of neurons in the brain, and even serious psychological disorders.

It may be pointed that children who were raised in specific conditions and happened to be brought up by animals suffer from the lack of adaptation for the rest of their lives. For instance, children who were born in the isolated villages of Dominican Republic suffered from strange transformations of their bodies.

All babies in the womb, whether male or female, have  internal glands known as gonads and a small bump between their legs called a tubercle. At about eight weeks, male babies who carry Y chromosome start to produce testosterone in large amounts, which turns the tubercle into male genitals. This condition can be explained by the fact that a lot of villages in Dominican Republic have been isolated for years. And this example is not a unique one.

The human raised without the social contacts would necessary be free of the time frames. Isolation distorts the notion of time and disturbs the natural cycle of ‘wake-sleep’. Medical innovations cannot assist in helping these people adapt to the normal rhythm of life. The thing is that the feeling of time can be developed only with the help of specific social processes such as feeding, breastfeeding, walking, playing and other social activities.

If the child did not come across these procedures in his childhood, he would be raised with the distorted vision of time and never get used to the usual daily routine. The consciousness of the isolated person is distorted to such an extent that it is impossible to revive the normal state of things.

The isolation can be harmful even for adult people. People who experience lack of sunshine for a long period of time, experience so-called time shift. A brave man Michael Siffre decided to research the underground icebergs in the Alps. Spending about a month under the Earth, he pointed out that his teeth became bigger, he got much hair on his face and he could calmly live without sleep for about 48 hours.

When returning to his normal life, researcher found that he could no longer spend time in the open sunshine and sleep every night. Moreover, he started hearing strange sounds might be regarded as hallucinations similar to those he experienced under the Earth. Michael concluded that his armchair seemed to be moving around when he stayed seated. He could never return to the normal state of things and experienced hallucinations from time to time.

Researcher Anna Ludoviko is dealing with those children who were brought up in isolation for more than five years from birth. She claimed most children were raised alongside with wolves, bears and even hyenas. Anna had to work with a 4-year-old girl Kamala brought up by animals in the forest.

She had very long and calloused hands, sunken cheeks, large and flat ears. When she sniffed, her nostrils narrowed and expanded. She was almost insensitive to heat and cold. The girl ate only raw meat and drank milk. In addition, she had extremely powerful lower jaw and sharp teeth. Kamala lived with people for several years and died. In all cases, children who have returned to the people after living among the animals did not survive long.

In 2003, the world was shocked with the real story of children raised in the family of New Yorkers. This story became the documentary movie The Wolfpack. The head of the family closed the children in the room as he was afraid to let them out.


When they were not being home schooled by their mother, the Angulo siblings were allowed to watch movies nonstop. Their story is told in “The Wolfpack,” directed by Crystal Moselle

After 14 years the children were able to escape. They never saw the city, and had to study the surrounding world themselves. All children were suffering from paranoia and physiological instability. Moreover, any bacteria coming to their organisms caused the disease. However, they were able to survive and adapt to the society. Perhaps, this is the only story with happy ending.
