Why Are New Generations Getting Taller?

The fact that the ceiling and door of the old village houses are shorter is also related to this situation. You may have to bow your head when entering these residences. This is because previous generations were shorter than today’s generation.

The average height of people one century ago was considerably shorter than today’s average height. People who could be considered tall for that period had a stature that could be regarded as short for today.

Length differences are affected by genetic variation, but of course, this is not the only reason.

Geographic distribution of the average height of people aged 18 years (2014)

The distribution of height by the measure of environmental diversity may also be affected. The main reason for this situation is related to this. A genetic variation would be the only factor affecting the length distribution in a population with identical health and nutrition rules. Still, these conditions are unlikely to be equal all the time.

Since the rules are not the same, wealthy individuals who can reach more proper nutrition and health rules are taller than poor individuals who are deprived of them. Genetic diversity is not the only determinant, and the effect of environmental diversity in the length distribution is felt to a significant extent.

If we give an example from the caste system in India; It has been determined that individuals in a high class are on average 4.5 cm taller than individuals in a lower class.

In a study conducted in Spain, it was determined that educated people are approximately 1 cm taller than uneducated people. Low-status workers (eg, agricultural workers) with less access to health and nutrition were found to be on average 3.6 cm shorter in length than higher-status workers (eg: lawyer, doctor).

Nutrition quality in childhood is very valuable, new generations are getting longer as the quality has improved in the last century.

Average length from 1800 to 1980 (top to bottom) of the Netherlands, Germany and France, respectively

And not just length quality The quality of intelligence also increases with a good diet.

It is customary that length has an end, of course, we will not turn into 5-meter creatures one day, and we will enjoy the privileges of adequate nutrition as much as our genetics allow.
