Human evolution is still happening - possibly faster than ever

Human Evolution

Evolution is a gradual change in the DNA of a species over many centuries, occurring by natural selection when traits created by genetic mutations promote survival or reproduction in an organism.


By looking at global DNA studies, it is evident that human evolution hasn’t stopped, but is happening at a faster rate than before.

Key Ideas

Stretch Genes

  • Human beings adapt to their environments genetically, over a period of time. 
  • Developing countries having populations with no access to proper health care continue to survive and thrive. 
  • In countries where infectious disease outbreaks have occurred in the past, survivors develop a natural resistance to the disease and pass it on to their offspring. 
  • People living in higher altitudes develop a mutated gene that increases blood oxygen content, resulting in better survival in the next generation.

Our Diet

What we consume or don't consume influences our genes. Example: Countries where milk isn’t taken commonly, develop lactose intolerance and other digestive problems.


Our Ultra-processed and super-unhealthy diets are also contributing to genetic adaptation, with studies showing changes in blood pressure and cholesterol levels. The upcoming result of this mutation of DNA is uncharted territory and will be more fully understood in the coming decades.

Biased Gene Conversion

Certain molecular repairs seem to be happening in a biased way in our bodies, according to recent scientific studies of the genome. Certain ‘fast-evolving’ genes are rapidly accelerating, causing a fast rate of evolution. 


This is currently being studied and is pointing towards new kinds of genetic problems for future generations.

Evolution: Shaping Up Humans

Processed food has aided the evolution of Homo Sapiens: As food became easy to eat and digest, our jaws and teeth became less powerful and smaller.

The shape of our brains and even the development of language resulted partially from our eating habits in our evolutionary path.

Changes in DNA
Processed food has changed our DNA and the way we look. 

The current crop of super processed foods is altering our insulin resistance, teeth, metabolism, brain chemistry, and internal organs.

Collaborative Interdependence

Hundreds of studies on plants and animal behavior in recent years reveal that living things, including humans, are in reality multispecies events of collaboration and interdependence.

This is seen in the way fungus helps nurture and connect trees, or the way algae and coral form a partnership to create colorful coral reefs.

Life is more complex and collaborative than previously thought.

The Climate Crisis

The recent findings which prove that competition is not natural, at least not more than collaboration, pave the way to think about our relationship with the planet, and the millions of species inhabiting it.

Environmentalists are tackling the climate crisis assume that people are by nature bound to harm ecology, and will consume and plunder the natural resources. This leaves them with a narrow set of solutions to control the crisis.

DNA tests are still considered estimates, due to imperfect data.

When a person wanting to give the test provides the DNA sample through the saliva, the company checks for variance in the saliva, as 99.9 percent of the DNA is the same in humans.
