How Humans Have Evolved in Just 150 Years and 7 Big Changes in Our Bodies

The origin and evolution of the human species are taught in classrooms as an event that took place thousands of years ago. The study of this process is addressed as if it belonged to history and not precisely as a biological question. We think that hominization, or human evolution, ended with our ancestors, the Homo rhodesiensis, and we ignore the fact that the human body of today has also undergone adjustments in recent years.

Virala Buzz will show you the evolution of the contemporary human body.

1. An increase in height

How Humans Have Evolved in Just 150 Years and 7 Big Changes in Our Bodies

There’s evidence that human height has risen over the past 200 years. A study from the scientific journal eLife showed that both men and women were seen to have height increases in various countries around the world, especially South Korean women and Iranian men, who became 20.2 cm and 16.5 cm taller on average.

2. Body temperature

While the planet’s temperature is on the increase, human body temperature is on a decline. Researchers from Stanford University have confirmed that men from the 21st century have decreased their body temperature by 1.06ºF, in comparison with data from the 19th century. Data from the 1800s shows that women have also experienced a decrease of .58ºF.

3. Early puberty

Boys and girls reach adolescence earlier than children from a century ago. This is due to good nutrition and health. According to a study from the University of California, 15% of girls start puberty at 7 years old. Puberty is estimated to be one to 2 years ahead of what early 20th century records state.

4. Longevity

The life expectancy of the human body has increased because of advancements in sanitation, nutrition, hygiene, and other factors. A report, published by the Santalucía Institute in Spain, predicts that longevity will continue to rise until it reaches 120 years by the end of the 21st century. If we compare data from the beginning of the 20th century, in which only 26.2% of the population survived to age 65, we can say that many millennials will become supercentenarians.
